绵核桃剥壳取仁机的研制

根据薄壳理论，分析了均匀薄球壳在不同受力情况下壳体内应力及位移大小和方向，得出了二对集中力滚动挤压有利于壳的破碎的结论．核桃近似球体，表面也不光滑，通过大量的实验得出了同样的结论．在此基础上，论述了一种能自适应绵核桃尺寸和形状的新型剥壳取仁机．

The Developing of the Machine Which is Used to Peel off Walnut's Shell

According to the theory of shell,This paper analyses the different internal stress and the direction of displacement of shell different condition of force. and concludes that rolling extrusion of two pairs of force is of the most benefit to smash the shell into pieces. A walnut is similar to a ball, and the surface is not smooth. After much experine mentation, We have a conclusion that the above theory can be applied to walnuts. On the basis of the above theory, We expound a new and original structure which can be adapted to the walnut's dimensions and shape automatically, through which the quality of peeling off the walnut'S shell is guaranteed.
