摘　　要：该文提出了银杏的几何模型和破壳受力模型 ,通过有限元分析方法对银杏在各种施力状态下的应力分布进行分析 ,找出了最佳的施力方向与施力方式 。The geometric dimension of gingko fruit was measured and the finite element model for shelling gingko was put forward in this paper. The stress distribution and strain of gingko shell are analyzed under different conditions of force or pressure. The optimum direction and pattern of pressure are found out and the device for shelling gingko was developed on the basis of previous analysis.
