Abstract:

T
he flow field at the outlet of impeller in the designed axial
-
flow pump was measured
by using the five
-
hole probe. Three

velocity components and circulation curves were
obtained. The measured results show that the flow field at the outlet of impeller is a
spiral movement. Under the optimum condition, the rotary kinetic energy occupies
34% of the total outlet kinetic energy and decreases with the increase of the flux.
Accompanied by the small radial velocity, the axial velocity increases with the flow
intens
ifying. The velocity circulation decrease from the hub to the flange, wherefore
the more circular velocity at the flange and the less at the hub are needed. The 3
-
D
velocity distribution of flow field can be measured accurately by the probe. This
method ha
s the merits of simple operation and well applicability.

Abstract:The drive screw was simplified as a rotating Timoshenko beam bearing the pre
-
tension
force and moving forces, and the frequency equation of the screw with the elastic end
supports was

derived under considering the effect of gyroscope, the pre
-
tension force,
the moving forces on the screw vibration, and the bearing stiffness. The dynamic
model of the drive screw was established using Lagrange equation, and was analyzed
adopting the mode

superposition and Runge
-
Kutta method to calculate the transient
response. Eventually, the effect of the system parameters on the whirl speed and lateral
vibration was studied to supply a base for designing the drive system.

Abstract:

Due to the

characteristic of non

linear dynamic, time
-
delays, external disturbance and
parameter uncertainty, the automated clutch is difficult to be controlled precisely. A
sliding mode controller was introduced to control the automated clutch effectively. The
slid
ing and global stability conditions were formulated and analyzed in terms of
Lyapunov full quadratic form. The rapid control prototyping of automated clutch was
built based on dSPACE. The experiment results show the controller is effective and
robust to th
e parametric variation and external disturbance.

Abstract:To improve the grafting rate of 2JSZ600 vegetable grafting machine and the survival
ratio of vegetable seedling grafted, a high
-
speed vegetable grafting machine with
double manipulators was developed based on the
essential structure of the old machine
with a set of manipulators for transporting stock and scion added and the geometrical
parameter of cutting mechanism optimized. The key structural parameters were
determined by mechanism analysis and experiment. The c
utting effects of stock and
scion were best when angular velocity of cutter was 210 r/min. The experimental
results indicate that the average grafting rate of the machine is 854 seedlings per hour
and the survival ratio is 93.3%, compared with the old mach
ine, under the condition of
the same grafting success rate and adaptability to seedlings. The grafting rate and the
survival ratio are increased respectively 42.3% and 3.3%.

Abstract:In order to implement the parametric optimization design of centrifugal pump blade
, the
partial differential equation was used to design the impeller meridian plane and the 3
-
D
blade surface. Firstly, quartic Bezier curve was employed to design the meridian plane,
and then the partial differential equation was introduced to produce the
original
streamline and meridian quasi
-
orthogonal lines. Secondly, the partial differential
equation was used to generate the centrifugal pump blade surface. According to the
blade streamline equation, the angular coordinates of dispersed points on pump bl
ade
boundary was calculated from the distributions of blade angle on boundary.
Consequently the boundary
-
value of the partial differential equation was determined.
The blades geometries was controlled by adjust the distribution of the blade angle
along hub

and shroud. The relation between the 3
-
D model of pump blade and the
pump design parameters was built, to achieve the parametric design of pump blade.
The gradient optimizing method was introduced to realize the optimization of pump
blade. The calculation

result of the flow field was used to renew the shape of pump
blade. The calculation case shows that the presented inverse method of centrifugal
pump blade is rational.

Abstr
act:

Using three parameters (the change of accelerator aperture, the vehicle speed, the
accelerator) shift control in AMT vehicle, the vehicle speed response lagged to the
change of accelerator aperture for the large inertia of the automobile, and the
phen
omenon of shifting frequently occurred when accelerator aperture varied
extensively. The fuzzy control method was proposed on the base of three parameters
into which the change of accelerator aperture was added. Meanwhile, aimed at the
problem of excessive

input parameter and rule, the method of double fuzzy rule was
proposed which reduced the amount of rule, improved the processor operation ability.
The simulation results verify the validity of control strategy.

Abstract:

In order to solve the problem of the high cost and long period of ABS calibration and
matching using threshold control method, the theory of brake decay power was applied
to ABS calibration. The shortages of conventional method of matching ABS

were
analyzed. Utilizing the advantages of threshold method and brake decay power theory,
the ABS calibration and matching method for vehicle based on brake decay power
theory was put forward. According to theory that the slip rate by max of brake decay
p
ower approaches slip rate by peak of adhesion coefficient very well, the

slip rate by
max of brake decay power can be used for ABS control. The curve of relations
between slip rate and brake decay power can be obtained simply relatively, so the
period of A
BS calibration can be shortened. Vehicle test proves that it can enhance
matching efficiency observably and economize calibration cost largely.

Abstract:

In order to understand the effect of condition and design parameters on trapped oil
pressure in external spur
-
gear pump, based on the geometrical relationship of gear
transmission of external spu
r
-
gear pump and relative position with relief groove, a new
dynamic trapped oil model including equation of trapped oil pressure and dynamic
coupled equation of gear pair was derived from the calculations of trapped volume and
it's first derivative and exc
hange flux from inside to outside of trapped volume and
dynamic backlash value. Thereby simulation results of trapped oil pressure were
produced and compared with tested results published in a literature. All results
indicated the simulation results from d
ynamic trapped
-
oil model were greater in value
than static trapped
-
oil model with trapped
-
oil pressure p2 exceeding p1, besides, all
involved parameters discrepantly influenced trapped
-
oil pressure, accordingly
optimization of operate parameter was necessi
tated. Finally, the validated trapped
-
oil
model was thought to be right and reliable for forecast on trapped
-
oil pressure as well
as vibration analysis along with vibration evaluation and optimization of entire design
of gear pump.

Abstract:The simulation of cavitating flows in hydraulic runner for the hydraulic optimal design
was presented by using the two
-
phase flow method through the solution of the
time
-
average Navie
r
-
Stokes equations based on the mass transport equation. The
results show that the efficiency apparently increases from 93.4% to 94.7% when the
wrap angle of the blade enlarges and the trailing edges of the blade extend. The
pressure on the blades is well
distributed and the critical cavitation coefficient at
optimum operating condition is lower than unmodified, 0.03, and the cavity domain
are also decreased. Finally, the cavitation performance of runn
er is

improved. The
computational results, which agree w
ith experimental data, provide a correct direction
for further optimal design for the runner.

Abstract:

The hardware system of an intelligent detection for growing crop

was developed based
on multi
-
sensor information. The stable light source was obtained from the detection
chamber, and the temperature, humidity and lighting levels could be set in the system
that could be used to simulate some growing environment of crops
. The information
including the spectrum information, multi
-
spectral image, canopy temperature and
canopy lighting level for crops and ambient temperature, humidity information was
collected by multi
-
sensor information acquisition system by which the crop
growth
information could be monitored effectively. Then, the system was used to detect the
spectral and the multi
-
spectral image characters for the rape nitrogen level and the
water content. Meanwhile, the influence of the light intensity was investigated
for the
detection system. The results showed that the influence of the environment factor on
the results can be eliminated. The exact and quantitative analysis about the rape
nitrogen content and the water content can be carried out by means of the multi
-
s
ensor
information technology. The linear relationships between nitrogen content and spectral
reflectance value is 0.92, with the RMSE of 0.53.

Abstract:

Emulsified fuel from biomass pyrolysis derived
bio
-
oil and diesel was prepared and
fueled to a laboratory diesel engine tester. The experimental bio
-
oil was obtained from
the pyrolysis of corn stalk powders in a fluidized bed reactor. The emulsified fuel was
produced by mixing the bio
-
oil with commerci
al No. 0 diesel oil as well as surfactants
using a homogenizer. The performances of bio
-
oil/diesel oil emulsified fuels with two
different bio
-
oil/diesel oil ratios were tested on a ZS1110 diesel engine. Consequently,
the load characteristic and exhaust em
ission characteristic curves of diesel engine were
determined, and the specific fuel consumption and effective thermal efficiency of the
engine fueled with the emulsified fuel were analyzed in comparison with that of the
pure No. 0 diesel oil. The experime
ntal results show that, when the engine is fueled
with the emulsified fuel at bio
-
oil concentration of 15%, the specific fuel consumption
is lower and the effective thermal efficiency is higher than that of the pure No. 0 diesel
oil. The highest fuel savin
g rate reached 10%. Moreover, the NO and CO emissions are
lower than that of the pure No. 0 diesel oil.

distribution and vortex's structure and evolution characteristics of wake region and
other flow message were captured. The results showed that static pressure is
asymmetr
ic in impeller. And the reason for vortex forming in separation chamber was
analyzed. The gas fraction distribution shows that gas phase mainly centers on the
blade suction interface zone in the impeller. Performance prediction was carried out
and performa
nce curves were gotten. The performance experiment results was
conducted and compared with prediction results. Large eddy simulation was accurate
in predicting performance and interior flow characteristics.

pressure and film height were listed. In addition, the structure and key technological
problem
s for the dynamic test device, with the film height feedback by
electrohydraulic control, were introduced. Test results of film height at several points
on sealing area of plane pairs, leakage flow, and frictional torque and so on, show that
supply pressur
e greatly affects lubricating the height and its figuration of film, and that
the cylinder block surface wear mainly resulted from destruction of film.

Abstract:

In electrostatic charged spray, the electrostatic and polarization forces produced by
high electrostatic field coupled with fluid forces act on the droplets which has a
marked effect on th
e motion characteristics of the droplets. To analyse the charged
twin
-
fluid spray structure, the effects of electrification on spray structure and
aggrandizement of heat and mass transfer were discussed. Furthermore, PIV
technology was employed to measure
the gas
-
liquid twin
-
fluid electrostatic spray, and
the collected flow image was send to the computer via data line by the image grabber
card. The spray images data were analyzed by using Insight 3. 3 software and then
flow velocity and streamlines were gai
ned. The experiment results indicated that the
twin
-
fluid electrostatic spray has the special spray flow structure. The distinctly
different structures with main jet flow section, up convolution section, down
convolution section and influence section in th
e spray flow field were formed. The
complicated eddy current effect comes into being in the twin
-
fluid electrostatic spray
from single convolution phenomena, which could make the droplets contact with gas
medium easy, and enhance the droplets absorbency.

Abstract:

An L9(3)4 orthogonal test was carried out to evaluate the storage quality of Agaricus
bisporus unde
r active modified atmosphere packaging with different temperature,
packaging material, O2 and CO2 volumetric concentrations. Weight loss, fructification
firmness, degree of browning, the respiration rate, membrane permeability, soluble
solid content, polyp
henoloxidase (PPO) and peroxidase (POD) activity of Agaricus
bisporus were determined on the 3th day, 5th day, 7th day, 9th day, 11th day after
storage, respectively. Study results suggested that, storage temperature was the most
important factor affecting

the storage quality of Agaricus bisporus, and a low storage
temperature was essential to the preservation of Agaricus bisporus; the optimum
treatment of active modified atmosphere packaging for Agaricus bisporus was that
storage temperature 2°C, packaging

material PVC2, 15% O2 volumetric concentration,
10% CO2 volumetric concentration.

Abstract:

Based on Matlab, BP neural network model for efficiency and head of centrifugal
pu
mps with compound impeller predicting was established. Seventy
-
three groups of
experimental data were selected as samples for BP neural network training with
Levenberg Marquardt law. Then twelve experimental data extra was random selecting
to test the trai
ned BP neural network. The main parameters for experimentation are
flow rate Q, the number of blade z, outlet angle of blade β2, inlet diameter of splitter
blade Di, outlet width of impeller b2, efficiency η and head H. Select Q, z, β2, Di, b2
as input lay
er, η and H as output layer. The results show the predicted value favourably
accorded with experiment. So it is possible to use BP neural network for predicting
performance of centrifugal pumps with compound impeller. BP neural network can be
applied to co
mpound impeller designing, which can shorten experimental time and
reduce cost.

porous material on the base of the
relationship between the shrinking volume and average moisture content of particle.
The changes of boundary radius, shrinkage displacement and the tissue shrinkage of
every element layer of the pea at 40°C were cal
culated. As suggested in the result, the
external of the pea firstly appeared contraction due to water loss, rather than
synchronous contraction from the outside to the inside with the wet sub
-
external
migration and humidity decrease during the drying proc
ess for the pea. There is no
shrinkage of parts of no loss water. Furthermore, the external shrinked more greatly
than the internal due to more water loss in the external of the pea.

Abstract:

The effects of temperature on anaerobic digestion for biogas production were
investigated. The tests were carried out in self
-
made anaerobic fermentati
on devices,
with cabbage leaves as raw materials. Results showed that the value of VFA, NH+4
-
N
and pH values at mesophilic fermentation ((35±1)°C) was in normal range superior to
thermophilic ((55±1) °C) and room temperature. The total yield of biogas at
m
esophilic fermentation was 42.5% higher than thermophilic fermentation. The CH4
content at mesophilic fermentation was 7.6% and 19.1% higher than thermophilic and
room temperature fermentation, respectively. Therefore, mesophilic fermentation
condition is
considered suitable for biogas production from cabbage leaves.

Abstract:In order to understand the kinematic properties of the tripod sliding universal joint, its
ki
nematic model was established. First, the relation between the input and output
angles and the relative displacements of the slide
-
rods to the input shaft and to

the
tripod were obtained by using coordinate transformation technology. And then, the
expressi
on of the fluctuation of the joint angle was derived from the cross product of
the centerlines of the input and output shafts. The numerical results show that the
output angle error, the angular velocity error of the output shaft, the joint angle and the
r
elative displacements of the slide
-
rods to the input shaft and to the tripod are all
periodic and similar to a sinusoid. In addition, the output angle error, the angular
velocity error of the output shaft and the joint angle have a threefold frequency of t
he
input shaft, whereas the relative displacements of the slide
-
rods to the input shaft and
to the tripod have simple and twofold frequencies of the input shaft respectively. The
gained results agree well with the main documents, and validate the present m
odel.

Abstract:

Two kinds of persimmon vinegar after accomplishing fermentation with natural and
conventional fermentation ways was aged for 180 days at 3
-
6°C. Aroma components in
the two kind
s of persimmon vinegar were extracted by solid phase micro
-
extraction
(SPME), then separated and analyzed by GCMS. About 63 kinds of volatile
compounds were identified from persimmon vinegars with two different fermentation
ways, respectively. Acids, ester
s, alcohols, hydrocarbon, aldoketones, phenols and a
few other compounds exist in the volatile compounds. The content of esters, alcohols
and hydrocarbon in volatile components from persimmon vinegar fermented with
conventional way is 33.78%, 32.38% and 1.
08%, respectively, and is bigger than with
natural fermentation way. The content of acids, aldoketones and phenols fermented
with natural fermentation way is 61.25%, 9.66% and 6.13%, and is bigger than
fermented with conventional way. The sensory quality o
f persimmon vinegar
fermented with conventional way is better than fermented with natural fermentation
way.

speed
magnetic pump, with the diffuser grid and not, was numerical simulated by Fluent
program. The distribution of pressure was taken out, and the
trace of the particle was
plotted. The main characteristics of the interior fluid field of the two pumps were
obtained by comparing with two groups of data. The results show that the pump with
the diffuser grid of changeable position in axial direction can

improve the
anti

cavitation performance. The application examples from practical tests favorably
validated the results of simulation, which provide theoretical basis for improving the
design.

Abstract:

A conceptual design of a novel six
-
axis hybrid machine tool with five
-
face machining
capability was proposed. Based on the relative motions between the typical cutter and
workpiec
e, the transformation matrix between the cutter and the workpiece was
obtained. The transformation matrix was realized by the hybrid kinematics model of
the machine tool. In this conceptual design, the few degree
-
of
-
freedom 3PRS parallel
mechanism was adop
ed at the spindle component to realize the linear Z
-
axis motions
and rotary A and B
-
axis swinging motions, and the XY parallel driven mechanism and
the C
-
axis NC rotation workbench were employed at the worktable side. The spindle
component driven by 3PRS p
arallel mechanism has the capability to swing ±45° by
lean layout and designing component reasonably. The kinematics, rigidity and the
workspace of the 3PRS parallel mechanism were analyzed. Also the force bearing of
the XY parallel platform and the 4 guid
es of the X
-

and Y
-
axis sliding tables was
investigated.

Abstract:

The influences of angles (45.0°, 60.0°, 67.5
°, 75.0°) of dental labyrinth channels drip
emitter on hydraulic and anti
-
clogging performance was studied by the following
methods: the CFD numerical simulation of the velocity in the flow field, the PIV
observation of the trajectories and velocity of par
ticles in flow path and the samples
experiment. The results showed that there is a negative relationship between angle and
discharge coefficient together with flow state exponent, in addition with the increasing
of the angle of emitters, the anti
-
clogging
ability declines. Therefore, combining the
hydraulic and anti
-
clogging performance, a reasonable angle of 60.0° is put forward.

Abstract:

By means of scanning electron microscope (SEM), Fourier transform infrared
spectroscopy (FT
-
IR) and optical contact angle measuring instruments, the
microstructure, ingredient and hydrophobicity of
dragonfly wing surface was
investigated. Results show that dragonfly wing surface is covered with large number of
papilla, leading to the composite contact between liquid droplet and dragonfly wing
surface, which enhances the hydrophobicity of dragonfly wi
ng surface. The waxy layer
increases the hydrophobic capacity of dragonfly wing surface. Moreover, the
hydrophobic equation of dragonfly wing surface was established through the Cassie
model, and the multivariate coupling mechanism of dragonfly wing surfac
e was
analyzed. It is the conclusion that the hydrophobicity ascribes to co
-
coupling of the
microstructure and ingredient of dragonfly wing surface.

Abstract:

Due to the variable heat source problem for an a
dsorption cooling system in the
practice, a silica gelwater adsorption chiller was experimentally studied, which was
driven by recovered heat from gas engine. The chiller consisted of two
desorption/adsorption chambers and one heat
-
pipe working chamber of
evaporator.
The experimental results show that the cooling power with the 65°C variable hot water
temperature attains 63% of one under 90°C, and the COP (coefficient of performance)
of the chiller has a small change which may be ignored. The transient refr
igeration
performance of the chiller has the good repeatability and stability. It was proved that
the chiller driven by variable heat source is very reliable and good for low
-
grade heat
source. This technology approach is feasible to be used for low temper
ature grain
storage with combination of adsorption cooling and solar thermal or waste heat
utilization.

Abstract:

For reduction of scattered point cloud data, one algorithm based on non
-
uniform
subdivision was put forward. The space partition of point cloud was generated using
octree structure. k neighborhood was constructed through partition result. All

the
points in the k neighborhood were approximated by quadratic parametric surface of
which the mean curvature determined whether to carry out non
-
uniform subdivision
for the octree space or not. In the process of subdivision, the degree of subdivision
de
pended on the maximum interval angle of each data point. Boundary points were
identified and protected by constructing curvature difference function. The algorithm
was applied for reduction of point cloud with curvature diversification. The reliability
and

accuracy of the algorithm were validated by experimentation.

Abstract:

By using powertrain system analysis toolkit (PSAT) w
hich is kind of software with
forward simulation approach and divided rectangles (DIRECT) global optimization
algorithm, an energy management control strategy for a parallel plug
-
in hybrid electric
vehicle (PHEV) on different charging depleting range (CDR)

were studied. The results
show that as the CDR increases, the impact of control strategy parameters on PHEV
economic performance becomes smaller. By applying small

CDR optimal control
parameters to PHEV, its average economic performance is better than tha
t of
large

CDR optimal control parameters. The final optimal energy management control
strategy can reduce PHEV average equivalence fuel consumption to 2.70L/(100km),
which is 58% lower than that of prototype vehicle.

Abstract:

The vehicle stability characteristic was
represented by coupling of state variables, the
front or rear tyre side slip angle and its angular velocity. To improve the
maneuverability and stability of vehicle, a fuzzy supervisory control based on
integrated control algorithm was implemented to coord
inate the subsystems of the
vehicle chassis control system. According to the control weights assigned by the upper
supervisory controller, the subsystems including active steering control, active
driveline control and active brake control were proposed to
achieve their performance
targets independently. An 8
-
degree
-
of
-
freedom nonlinear vehicle model was used in
simulation to verify the integrated algorithm through critical test maneuvers.
Simulation results confirm that, compared with the conventional stand
-
alone or
combined controllers, the proposed hierarchical control algorithm provides vehicle
with better performance of maneuverability and stability, while avoiding conflicts
among the subsystems and decreasing consumption of the control.

Abstract:

Based on the assumption that every section of pipeline is composed of two diameters, a
mathematical model for optimizing the pumping tree pipe network was presented with
the objective function of annual cost, using pump head, pipe len
gth and standard
diameter as decision variable. The infeasible degree function of solution in the species
group was defined, and the constraint condition was handled by adopting annealing
algorithm based on the infeasible degree of solution. The infeasible

degree of solution
was locally optimized through simulated annealing, to make it gradually approach
feasible solution. Combined with the genetic algorithm global optimization and good
local search capabilities of simulated annealing, a simulated annealing
-
genetic
algorithm for the optimized design of the pumping tree pipe network was established.
Simulation results showed that the model and algorithms have good performance for
optimizing the pumping tree pipe network.

Abstra
ct:

Disc infiltrometer with two diameters (diameter of 5cm and 15cm) and two distinctly
textured soil (Yangling caly soil and Shenmu sandy loam soil) were used to carry out
disc 3
-
D laboratory infiltration experiment under five pressure heads (0,
-

-
9,
-
12cm).
The effects of different disc diameters and pressures on cumulative infiltration were
studied. Four methods of estimating sorptivity were applied to calculate permeability
of these two soils and their applicability were analyzed according to Vanderv
aere
equation. The results are as followed: the cumulative infiltration capacity of 5cm disc
diameter is bigger than that of 15cm disc diameter in the same while. The cumulative
infiltration capacity of Shenmu soil is higher than that of Yangling soil unde
r the same
pressure. Among these four methods, Haverkamp equation provides the closest
estimate to the references for the two textured soil.

Abstract:

In order to design and manufacture the bionic skateboard with the super slippery
function for catching in
sects, simulation on bionic slippery microstructure surfaces
based on OpenGL was presented and performed. The wax microstructure of
Nepenthes' pitcher superfaces was examined in scanning electronic microscopy
S3400N, and the images were collected for digit
al image processing and analyzing.
Under the Visual C++6.0 compile environment, the graphics development framework
of the OpenGL was established to realize the visualized simulation system of wax
crystal layer, for different status parameters. The simulati
on results show that
simulation crystal plates' length, thickness and height were

(1.00±0.20) μm,
(0.10±0.02)μm and (1. 00±0.70) μm respectively. Compared with experiment data, the
computer simulation has well accuracy and operation performance.

the collision and clogging of labyrinth channel emitter. First, the effect of Rc on pass
rate of sand was analyzed u
sing the CFD method. It was found that Rc has a great
impact on the anti

clogging characteristics of labyrinth emitter and should be
determined through experiments. In order to provide the experimental basis for the
setting of sand Rc in numerical simulati
on, experiments of PTV were carried out for
the determination of Rc under various pressure and different structure of labyrinth
channel emitter, so that the anti
-
blocking performance can be more accurately
evaluated.

Abstract:

Models of the position and tool forces of backhoe hydraulic excavator were
built
based on the full analysis of kinematics, kinetic performance of working device
and mathematic model of tool forces. Various restrictive factors of tool forces,
which appeared in the work process, were discussed. A computation program based
on VB 6.0

was compiled, which was used to calculate tool forces in any position of
the working area. Computer plotting of drawing mine map that was divided by
restricting factors was realized. The experimental results demonstrated the
feasibility of this method.
