Effect of kernel moisture content to the result of bare hand threshing of corn ear interval Li Xinping, Du Zhea and Ma Yidong College of agricultural engineering, Henan University of Science and Technology, Luoyang 471003, China aduzhe03@sina.com Key words: corn seed, law, moisture content, bear threshing.
Materials and Methods Preparation of test samples.The test of hand-picked seed corn for Ning Yu 524 which has tend to be hard grain type and conical body and Xun Dan 20 which has dent corn and conical body, moisture content are 19.1% and 19.0%.
(a) Ning Yu 524 （b） Xun Dan 20 Figure 4 Ear on different threshings moisture ,at different intervals ear bear contact force diagram From figure 3,threshing moisture content of ear has a great influence on the contact force of threshing kernel.When the moisture content of ear is 19.0%,kernel properties is similar to the plastic material,the fruit stalk coarsening, enhance toughness, mechanical strength increase,longitudinal and lateral of corn kernels have close squeezing and form a strong support.So the reasons are increasing the threshing force.Moisture content chang the interaction between corn kernels in some extent,but for the fruit stalk strength index,the moisture content of threshing kernel should not be too large.When the moisture content of ear are 16.7% and 13.5%,the contact force needed appear is large,ear kernel arrange most closely,and the kernel is not similar to the brittle materials and plastic
material,arrangement between kernels, fruit stalk,toughness are in normal state.So this moisture content is the most suitable for threshing.When the moisture content of ear is 9.7%,kernel properties is similar to the brittle material,the fruit stalk become thin and brittle,mechanical strength decrease,corn cob and kernel are likely to generate the volume contraction,reduce the squeezing role between kernels until arising gap,so it is easy to loose kernel,the contact force needed of threshing corn kernel decrease and may mutation.And this moisture content is too low, extremely dry, for the storage of moisture content,and kernel in this moisture content not suitable for threshing.

The carrying capacity of the jib is mainly affected by its material.
The mechanical property of the material which is used to manufactured the tower jib is of discreteness, as a result, the static strength is of statistical feature[5] .
Usually, the mathematical expectation and standard deviation of the material sample tensile mechanical property can be identify through the relevant design information.

Some factors that affect the sealing properties of the joint are the material of the gasket, the shape of the gasket and the clamped flanges but also the stiffness of the whole assembly.
Future Enhancements In the last several decades, the science and engineering community has progressively ventured outside of traditional boundaries in terms of materials, loads, configurations etc., for structural systems in mechanics.
By using this method another variable inputs could be taken into account, for instance applied loads (pressure applied to the cores of the unit), material properties of the gasket and of the other parts of the assembly as well etc.

The collision-prevention device named steel tubular truss in the thesis is made of angle steel and circular steel tube, which buffers taking advantage of the buckling deformation from angle steel and the bending deformation from circular steel tube.But actually,there are so many uncertain factors that make it difficult to analyse exactly when he ship impacts the steel tubular truss, such as the tonnage of ship, the shape of stem, the speed of collision, the location of collision, the angle of collision, the fluctuation of water level, the material of steel tubular truss and the differences of structural form and so on.
However,The Finite Element method is all admitted the most effective method at present,which can consider the big deformation , the touch , the nonlinear of material and avulsion，which can exactly calculate the relationship of deformation and coupling force in structure.
The body of ship will use the rigid material and the parameters are shown in table 2.The kinematic plastic material[4]-[5]related with strain rate applied for the Collision-Prevention Device is shown in table 3.

In contrast, the realization of BIM technology needs a series of software to solve problems, and the model made by BIM is only the “raw material” compared to what the client wants, and you still need to use other software to process the "raw material" into finished products.
