· Using pipe as the vane’s bearing beam, and using foam material, light wood or other materials as stuff.
At the same time, the interior of skin which made by glass fiber-reinforced plastic can be filled with foam materials.
The material of tower may be wood, metal pipe, column structure or trussed construction which made by steel material.[5] The function of every kind of tower is making wind wheel acquire stronger wind speed.
Acknowledgment We are very grateful to the Jiangsu Province College Natural Science Foundation of China for the support.

In the first and second windows the casting element size was, respectively, 2 and 5 mm and outside the windows it was 9 to 18 mm.The amount of element strain for automatic grid updating was assumed ε = 0.15 Fig. 4 – Density Windows in the deformation centers Steel AISI-1045 was used as a casting material.
The interaction between the casting and the tool was described by the Siebel friction law as where is friction strain, MPa; is the factor of friction forces; is material resistance to creep deformation, MPa.

The elastic-plastic material was chosen to model the vertebrae .
Because of the high water content ,the linear viscoelastic material properties were used for nucleus pulposus.
l In order to simplify the model, save the computation time and the limitation of material parameters to obtain, models for different parts of the same organization were used as unified materials, which may also result in the certain influence on the model of simulation.
