Abstract:Based on the results of the soil
-
bin test, the lunar soil

traction ch
aracteristics were
studied by DEM software PFC2D. The

linear contact
-
stiffness model was used as DEM
contact model for

describing lunar soil and biax
-
test was used to adjust the micro

parameters of particles. The results show that parameters of

simulated l
unar soil in this
simulation are close to those of the

lunar soil after adjusting the micro parameters. The
paper

researched the influence of the friction coefficient, porosity,

rmax/rmin and gravity
of the lunar soil to the traction ability of

lunar rover
. The results of the simulation test
show that the draw

bar pull (DP) increased with the increase of friction coefficient,

the
DP reduced with the increase of porosity, and the DP increased

with the increase of
rmax/rmin when the value of rmax/rmin is less

than 5. The DP is increased with the
increase of gravity and the DP

is 77.3% of the primary value when the driving wheel
passes the

lunar soil with 1/6 of the gravity.

Abstract:A curve of the tractor automatic mechanism transmission

(AMT) dynamic power shifting
schedule was presented by conducting an

experiment. Taking the degree of jerk during shiftin
g as
the primary

control parameter of the shifting quality, the AMT control system

was developed
based on the electric hydraulic servo system. By

analyzing the experience of a skilled driver, a
fuzzy controller was

designed, and the control algorithm of th
e tractor AMT dynamic power

shifting schedule was established. The experiment results show that

the faster the shifting is, the
bigger the jerk is. The biggest jerk

was 4.76 m/s3 that happened at the clutch's lock
-
up time, all of
the

jerk's values were sma
ller than 17.64 m/s3, which was the biggest

jerk that people can endure.
The results indicate that the fuzzy

control method is feasible for the tractor AMT control, and can

improve the quality of the tractor AMT shifting.

Abstract:In order to investigate the nonlinear behaviour which leads

the vehicle steady
-
state
cornering to destabilization, a 4D

(four
-
dimensional) nonlinear vehicle lateral dynamic
sys
tem

consisting of the roll and the planar motions was founded utilizing

a quadratic tire
model. Considering the relation between the vehicle

destabilization and the saddle
-
node
bifurcation in critical

conditions, a method for analyzing vehicle steady
-
state

cornering

stability was proposed based on the real
-
time tracking of the

closest bifurcation point.
The objective is to compute the shortest

distance from the current operating point to
bifurcation by

iteration method in the u
-
δf parameter space to evaluate the

steady
-
state
cornering stability margin. Testing computation

conducted in symmetrical and μ
-
split
conditions respectively

demonstrates that the closest bifurcation point can be found after
a

shor
t
-
time iteration which satisfies the real
-
time computation

demand and this method
can provide valuable information for vehicle

stability control system.

Abstract:A hydraulic model of controllable damping vane damper was

established based on th
e
structure analysis, the hydro
-
structure of

which was simulated. Based on test data in
di
fferent temperature of

damping force and velocity input, the parameters of the
hydraulic

model were identified by the least squares fitting method. At

different
temperature, the comparison of the test data and results

of calculation with the fitting
parame
ters show that the parameters

are reasonable and the method is valid. With the
fitting parameters

and calculation result, controllable damping vane damper design and

characteristic analysis can be supported. The result also shows that

the temperature can
i
nfluence the damping force, but controllable

damping vane damper can reduce the
trend which makes the damping

force lower.

Abstract:Electromagnetic field analysis for permanent magnet type

key part for designing. In order to

research e
lectromagnetic field distribution of the
retarder,

permanent magnet was made equivalent to a magnetized current. Flux

density

current density in the air
-
gap and rotor of

retarder were analysed and calculated
respectively based on Rogowski

method;
meanwhile, the computation formulae of its
braking torque

were derived in order to reflect the relationship between braking

torque
and different design parameters. The analytical model was

proved to be an effective
model that can reveal the essence of

elec
tromagnetic field of permanent magnet type
eddy current

retarder, and the comparison of bench test result and computation

result
shows that the maximum error is less than 10%, which means

Rogowski method is
effective.

Abstract:This paper focuses on the idling resonance problem of a

certain kind of vehicle. Based

on
the noise and vibration

measurement technology, the three dimensional vibration
transmission

path and vibration
-
sound coupling in the vehicle were analyzed. The

reason of idling resonance was that engine lateral vibration was not

reduced adequately
by
the mounting system, which caused the

frequency coupling between the engine's
twice rotational frequency

and the frame natural frequency. Optimizing the design of
mounting

system, the mounting rigidity and natural frequency of mounting

system were
changed.

Vibration isolation performance was enhanced so

as to improve the ride
comfort of the vehicle.

Abstract:A comprehensive theoretical analysis was made on the

conversion methods of efficiency
characteristics between prototype

and model pumps and pumping installations. Most
efficiency

conversion formulas existed did not analyze the theory sufficiently,

and the
conversion precision is not adequate. The formula

recommended by JIS B 8327
-
2002 and
the new formula recommended are

the

ones expressed more detailedly. But there are too
many empirical

constants in former one. The formulas of efficiency conversion

recommended are theoretical ones, and are applicable not only to the

pumps but also to
the pump installations. Quantitative exp
ression

for the influence of variety of factors
upon the results of

efficiency conversion can also be achieved by the formula.

Abstract:The open sump is a typical inlet passage of middle and

small pumping station. The
design parameters of sump affect

hydraulic performance of pump.
The incompressible
N
-
S equations are

solved by the finite volume method. Base on the RNG k
-
ε model, the

SIMPLEC algorithm is applied for the solution of the discretization

governing equation.
The results illustrate that, excessively small

backwall
-
clearanc
e (T) may lead to
unidirectional flow above

bellmoth and excessively large T may cause backflows near
back wall.

It can be observed that curvature of flow near bellmouth appears

large while
the bottom floor clearance (hc) is too small, but

excessively larg
e hc may cause larger
head loss and non
-
uniform

axial velocity distribution of blade inlet. The results show that

the hydraulic performance of rectangle sump, trapezia sump and

semicircle sump are
s
imilar, and the best one is ω
-
shape sump

because the distributing flowfield of suction
pipe is uniform. The

numerical simulation results show that the recommenced parameters

brought out and the best plane back wall shape and suitable

dimensions of sump
pre
sented could be applied in projects.

Abstrac
t:The forecast of axial thrust is a pivotal problem in the

design of centrifugal pumps,
especially in multistage pumps. The

existing axial thrust predict methods always cost
too much time and

resource in experiment; the experiential formula has lower preci
sion

and narrow application range. Through the numerical simulation of

the internal flow
field of deep well pump, this paper obtained the

pressure distribution of the pump axial
end
-
face and the impeller

surface, and the axial thrust was estimated accordin
gly. In
order to

obtain the axial thrust distribution in full condition, the

experiment for the
pump axial thrust was conducted. Estimated

results are closely matched with the
experimental results, and the

maximum error is less than 10%.

equation

turbulent model, the simulations of turbulent flow between impellers

are
performed by using the flow computing software Fluent under

different operating
conditions. Important flow features were

o
btained. With the computing result, the
distribution of velocity

and pressure in the impeller was analyzed. The pressure and
velocity

distribution in impeller are similar to those in general centrifugal

pump.
Obvious asymmetry of flow field was observed in

impeller in

case of large flow
operating condition. The internal flow in

impeller is mixed spiral flow and the vortex
core resulted by

relative eddy is close to the back blind flange and pressured side.

The
circumferential distribution of pressure and abs
olute velocity

at the outlet of impeller is
periodic, which is corresponding to the

periodicity of the passages of impeller. The
asymmetry of pressure

is relatively weak but that of velocity is strong.comparing the
data

of efficiency with the head produced

by experiment and CFD, the

result mainly
tallies.

Abstract:Spray characteristics are the criteria to evaluate variable

spray equipments and the ind
ex
to analyze the applicability of the

equipments. The switching mode solenoid valve was
driven by the

square signal with the tunable duty cycle and the adjustable

frequency
within 20 Hz. Through changing the turn
-
on and turn
-
off

time of the valve, the
int
ermittent pulse variable spray based on

pulse width modulation (PWM) was realized.
Taking flat
-
fan nozzle

commonly used in agriculture as an example, the spray

characteristics of PWM
-
based intermittent pulse variable spray were

discussed in the
aspects of
the change rules of flow adjusting

range, spray distribution pattern, spray
angle, spray droplet size,

droplet velocity and spray dynamic characteristics with flow

changing. The results of flow adjusting range is 4.17; spray

distribution pattern has
small
tend to concentrate toward the spray

center and the spray droplet size decreases
slightly when the

flow
-
rate reduces. The change rates of spray angle and spray droplet

size with the flow change are 0.0433 (°)/% and 0.616μm/%. It

indicates the effects are
a
ll very trivial. Spray droplet velocity

nearly has no change with the flow decreasing.
And the change rates

of kinetic energy median diameter (KEMD) and specific energy
(SE)

with flow change are
-
0.63μm/% and 0.2451 J/(kg·%) respectively. It

also indicates

that spray control has less impact on spray dynamic

characteristics.

agrarian competition with farming. In the long term, the

energy

oriented agricul
ture and
energy
-
oriented forestry deserve

more notices as the base of further development. Since
Chine started

the research and application of the modern bio
-
energy technology

rather
late, the overall level of utilization is quite low and leads

to an awkwa
rd unbalance both
in technological maturity and

commercial application, whose solution requires a
combined course of

independent research and assimilation of foreign experience,

breakthroughs of the key cruxes, and mastery of core technologies.

In China, t
he
development strategy of bio

energy industry should be

diversification of the material
and products, and intensification of

the interdisciplinary research according to various
technological

methods and processing.

Abstract:In order to investigate the heat exchange mechanism between

the ceramic balls heat
carrier, biomass particles and air, a

downward vertical flow tube of particles separation
apparatus was

developed
and the heat exchange experiments with ceramic balls heat

carrier and biomass particles can be conducted with the apparatus.

The feeding
experiments of particles showed that the feeding rate of

the ceramic balls and the biomass
particles were stable and th
ese

two kinds of particles were separated completely. Based
on the data

obtained from the heat exchange experiments among the ceramic balls

at
90°C and the air at room temperature, the convective heat

exchange coefficient between
the ceramic balls and the
air was

worked out and the value was about 291.3 W/(m2∙K).
The heat transfer

experiments of ceramic balls and biomass particles at the condition

of
ceramic balls' mass flow rate were 1.0, 1.2 and 1.4 kg/min, mass

ratio of ceramic balls
and biomass particle
s were 15, 20 and 25

respectively. The results indicate that the
temperature variation of

the biomass particles increases with the increase of ceramic balls

mass flow rate and the mass ratio of ceramic balls and biomass

particles.

Abstract:Four kinds of Chinese liquors were detected by the

colorimetric sensor array, which was
composed of thirty

chemoresponsive sensors. Principal component analysis (PCA),
cluster

analysis (CA) and back

used in the data analysis and pattern recognition.

With principal component analysis, not
only Chinese liquors could be

identified according to alcoholicity, but also bouquet.
Cluster

analysis further proved the result of PCA, but some samples c
ould

not be
classified by using this method. Finally, BP neural network

was employed to identify the
Chinese liquors, and the accuracy of

recognition was 100%. This research shows the
potential applications

of the olfaction visualization technology for ana

Abstract:The paper took edible oil, standard sample of trans fatty

acids and

odorless mineral spirit
(OMS) as experiment materials,

adopted Fourier transform infrared spectral
reconstitution (SRFTIR)

technique to detect trans fatty acid content in edible oils, the

results of which were compared with those obtained through standard

method
(SBATRFTIR method). The results indicate that the trans acids

content predicted by
SRFTIR is linearly dependent on the added

content, with a slope of 1.02 and an overall
standard deviation less

than 0.05. This paper provided a simple and accurate m
ethod
with

more than 20 times the sensitivity of the SBATRFTIR method.

Abstract:This paper studied the fe
asibility of using rapid and

non
-
invasive method to measure Fuji
apple firmness by FT
-
NIR spectra

techniques. Techniques of spectral analysis and
pre
-
processingincluding multiplicative scatter correction (MSC), standard normal

variate (SNV) and first devia
te (FD) were used. The result shows

that the MSC
technique can effectively remove the base shift and

deviation and remove the signal to
noise ratio of absorbance

spectrum greatly. The best statistical model was developed
using

partial least square (PLS) wi
th respect to multiplicative scatter

correction (MSC)
in wavelength range of 1408
-
2355 nm. The

correlation coefficient (R2) of the model
was 0.9852, the root mean

square error of cross validation (RMSECV) was 0.0398
kg/cm2 and the

root mean square error of

prediction (RMSEP) was 0.0166 kg/cm2.
Then

the model was optimized by weeding out outliers. Using the model to

validate 25
samples, the results show that R2 is 0.9908 and RMSEP is

0.0147 kg/cm2. It is
concluded that the model is reliable and the

predicted

result is effective. The method can
meet the requirement

of quick measuring of apple's firmness.

Abstract:To find reasonable position on the kiwifruit to collect

near

infrared spectrum info
rmation
for quality evaluation,

near
-
infrared spectrum was collected at different locations near the

equator on the kiwifruit applying the near

infrared spectrum diffuse

reflection technology.
Difference analysis on the average absorbance

and the noise of
the spectrum on the tested
locations was carried

out. The single factor variance analysis was conducted to the

near
-
infrared spectrum wave ridge position and the absorbance at

different locations, as
well as the prediction precision of the Brix

quantitativ
e analysis model. The results
showed that the variety for

the average absorbance and noise for the spectrum at different

locations around the equator on the same kiwifruit was low, and the

wave ridge position
difference was not remarkable. The difference o
f

absorbance was not remarkable at
different locations in the same

wave ridge position for the same kiwifruit. The relatively
standard

deviation of the absorbance was greater when the wavelength was

longer in the
near infrared area. However, the degree of
scatter of

data was not high at all wavelength
at different locations in the

same wave ridge position. The deference for the Brix
prediction

models built by spectrum data at different locations was not

remarkable. It is
concluded that the near
-
infrared spe
ctrum

information collected at different locations
around the equator of

the kiwifruit can be used for quality evaluation for the entire

fruit
without high difference.

Abstract:The effect of different fixing methods, drying temperature

and duration on the content of
chlorogenic acid and flavonoids in

Eucommia green tea were measured using
high
-
perfor
mance liquid

chromatography and spectrophotometry respectively. The
results show

that chlorogenic acid and total flavonoid content decrease

significantly
after fixing. Microwave fixing was the best fixing

mode, next came the dry fixing and
steam fixing, an
d the largest

decline of the activity contents was caused by blanching of
boiling

water. The optimum microwave fixing conditions were 800 W and 1min.

The
single factor and quadratic general rotation design experiments

suggested that roast
temperature and d
uration affect the active

ingredient obviously. After drying, the
chlorogenic acid content

decrease, and the total flavonoid content increase, but total

flavonoid content decrease when the temperature exceeds 200°C. When

the duration of
drying was 9 minute
s and the temperature was 130°C,

the content of chlorogenic acid
and the flavonoid reached maximum of

1.54% and 0.58% respectively.

Abstract:An idea that using fuzzy immune PID to regulate the density

of the starch
production
-
line was put forward after the analysis and

comparison of the principle of
tradition PID, Smith predictio
n PID

and fuzzy immune PID. A mathematical model of
one of density loop of

starch production
-
line was built to design and simulate these three

controllers. The simulation results show that the fuzzy immune PID

is better than
tradition PID on the hand of co
ntrol effect and its

robustness is higher than Smith
prediction PID. DDE protocol and

ActiveX of Matlab were adopted to realize data
exchange with

RSView32 of the starch production
-
line and transmit the algorithm of

fuzzy immune PID to RSView32.

Abstract:The optimal design was made on the parameters of the robot

framework and str
ucture
according to the growth distribution space

of eggplant. A joint type robot with 4
-
degree
freedom for fruit and

vegetable picking was developed. The fixed bilateral threshold
based

histogram was adopted to split the GB gray images. To meet the

vision

requirement of the fruit and vegetable picking robot, the

object's characters, such as
outline, area, center of gravity,

enclosing rectangle and the point of cutting off, were
picked up.

The performance test on the whole machine was done on the robot

syst
em
with the method of single camera and two
-
step measuring

distance, which shows that
the measure error is within ± 18 mm when

the measure distance ranges from 275 mm to
575 mm. The system runs

smoothly and reliably. The success ratio of picking is 89%
and

the

average time consumed is 37.4 s.

Abstract:The critical task of the robot vision system in the apple

harvesting robot is to recognize
and locate each single apple. To

solve recognition problems such as the big error, too
much

calculation and time consuming, a new recogniz
ing method, support

vector
machine (SVM) was applied to improve recognition accuracy and

efficiency. Firstly,
vector median filter method was used to remove

the color images noise of apple fruit.
Secondly, segmentation of the

images based on region growing

method and color
properties was done.

At last, color properties and shape properties of color image were

extracted, and the classification method of SVM for recognition ofapple fruit was used.
Experimental results indicate that the

classification performa
nce of SVM is better than
that of neural

networks. Recognition rate of apple fruit based on SVM combined
withcolor and shape properties is higher than only using the color or

shape properties.

Abstract:This paper proposed a method for corn

weed recognition by

using the combination
technique of image proce
ssing and support

vector machine (SVM). A gray processing
algorithm was proposed based

on the features of corn
-
weed color images. The object
could be

separated effectively by denoising the gray image. The shape

features of the
object were extracted and tak
en as feature vectors,

which could be used to propose the
SVM method for the recognition of

corn
-
weed.comparing the SVM method with the
neural
-
network one, the

former is better than the latter one seeing from the experimental

results. Experimental results
also show that the presented method is

effective, and this
method gives a recognition rate 98.3% with the

properly selected kernel function.

Abstract:An image acquisition system was designed for fruit machine

vision grader to obtain
image information about the whole surface of

each fruit in fruit flow on t
he roller
conveyor of the grader. The

conveyor could transport quasi

spherical fruits with different
size

and force them rotating with an approximately equal rotational speed

on the rollers.
With the conveyor and a synchronization control

system, a real
-
ti
me acquisition method
of dynamic image sequence of

the fruit flow was presented, which could acquire dynamic
image

sequence of the fruit flow with approximately equal fruit rotation

angle between
consecutive images. Experimental results show that the

image

acquisition system can
capture 6 sequential images of each

fruit in the fruit flow, and fruits regardless of size
rotate about

60° between two consecutive images. One complete revolution could be

done in 6 sequential images.

Abstract:A probe based on standing wave ratio (SWR) to measure stem

water content was
presented. Two experiments were taken to study the

configuration of probe: (1)
Simulation experiment. Different organic

solutions were chosen as the testing med
ia to
simulate the stem

which contains water. The result shows that the output voltage

changed
lineally with the length change of the probe. (2)

Calibration experiment. The sample of
arborvitae was selected and

the oven temperature was kept at 60°C constan
tly. The result
shows

that the relationship between water content of stem and the output

voltage was
linear. It can be concluded that the probe we studied

could be used to measure stem water
content.

Abstract:Based on the results of cone penetration laboratory tests

on alumina balls,
glass balls and
Toyoura sand, the discrete element

method (DEM) was used to simulate cone penetration
process.compared

the numerical simulation with experimental results, the curves of

simulation have the same tendency as those of penetration

experiment, w
hich indicates
that DEM can effectively simulate the

force between particles, the force between a
particle and the cone

when the cone is penetrating, and get the reasonable macroscopic

characteristics. Both the simulation and the penetration experiment

ind
icate that the
penetration resistance decreased with the increase

of the porosity. Finally, the influences
on the numerical

simulation, caused by the variation of mesoscopic parameters,

penetration speed, quantities of the particles and particle shape,

wer
e analyzed.

Abstract:A principle to determine the orifice area of spool valve

with two
-
stage notches was
propos
ed based on the series parallel

effects of fluid flowing in channel of the notches.
The formulas to

calculate the orifice area were obtained and the corresponding

computational program was worked out. Then, the experimental results

on the flow
characterist
ic of two
-
stage notches were analyzed. The

results show that the flow
coefficient of two
-
stage notch is the

combination of that of each single notch. When the
spool

displacement was small or near to full open, the flow coefficient

increased quickly.
At the

middle part of displacements, the flow

coefficient was about 0.7
-
0.8. The flow
coefficient in flow
-
out

direction was larger than that of flow
-
in, which was about 0.1. A

new concept of orifice area of flow control for defining the flow

control function of
the
orifice was proposed.

Abstract:Th
e coupling relations between the multi

characteristics and design parameters of
products were analyzed. An

index for measuring the coupling degree of multi
-
quality

characteristics was defined and a robust design criterion was put

forward to achieve

the
decoupling of characteristics approximately.

A modeling method of the robust design
with multi
-
quality

characteristics was proposed. On one hand, according to the

requirement of Suh's first design axiom (the information axiom), the

robustness of each
characteristic was optimized to reduce its

contents of uncertainties; on the other hand,
according to the

requirement of Suh's second design axiom (the independence axiom),

the
characteristics of a product were decoupled approximately to

improve the integr
ated
robustness. A back
-
propagation neural network

was designed as the substitution for the
nonlinear stochastic

functions in the established model. With genetic algorithm combined

with stochastic simulations, an intelligent optimization algorithm

was deve
loped for
solving the established model effectively. An

example was presented, and the results
show that this method is

effective and feasible.

Abstract:A constant scallop

height tool path planning method was

presented based on envelope
surface c
onstruction. Firstly, in the

process of calculation, the machined surface was
offset by the

distance of tool radius and scallop
-
height respectively, then the

scallop
surface and the tool center surface were obtained. Then the

envelope surface, whose
sectio
n radius was equal to the tool's, was

constructed along the last tool path. The
scallop curve was obtained

by the envelope surface intersection calculation with the
scallop

surface. The envelope surface was again constructed along the

scallop curve. The
ad
jacent tool path was the intersection line of

the envelope surface and the tool center
surface. All tool paths

could be determined by recurring in turn. A method of boundary

verification was described to avoid undercut. Finally the validity

of present meth
od was
demonstrated by an example. The calculation

results of the present method were
compared with those of the

existed algorithms. The results indicate that the machining

precision and efficiency can be enhanced greatly with three

Abstract:A method for improving machining precision of CNC spiral

bevel gear grinding machine
was investigated. The tooth surface of

spiral bevel gears was discret
ized and a method for
calculating the

position vector and normal vector of discrete points was developed

according to the mathematical model of the tooth surface. The

relation between
proportional change parameters and tooth form

errors caused by machining

errors was
analyzed. Based on the

proportional change parameters obtained from machine settings

calculation and freewill modification characteristics of grinding

wheel, a method for
compensating machining errors was proposed. By

applying optimization algo
rithm, the
coefficients of proportional

change parameters and the variation of grinding wheel
parameters

were computed. The proposed method was validated via practical

machining
on YK20100 grinding machine and inspecting on M and M

Sigma 7 gear measuring
i
nstrument. The results show that this method

can reduce the tooth form errors within
5.4μm.
