First , a simple model that a cyclinder with convex ring pulling in a tube is constructed using the ansys software , by computing and analysis of three different models , a general method can be get to resolve this sort of problems . then a complete projectile 2d model is established using autocad and converted to ansys through . sat data format , then a 3d solid model and finite element model is set up , and the properties are also defined in ansys . the next step is the dynamics analysis of the driver and body in the process 通过研究简化模型? ?带凸缘的柱体在圆筒中挤进过程，共对三个模型? ?二维挤进模型、凸缘在光膛圆筒中挤进的三维模型、凸缘在线膛圆筒中挤进的三维模型进行有限元分析，得到一个对此类问题的通用分析方法；然后，运用autocad建立实际弹丸的二维模型，通过sat接口程序导入ansys ，在ansys中进行前处理，包括生成弹丸实体、建立线膛实体、划分网格，设定单元、材料、接触的类型及其它参数，生成ls - dyna的
