摘　　要：应用Marc软件对径向摩擦焊焊接炮弹弹体和弹带的夹持模型进行了三维非线性接触摩擦的有限元分析比较,重点对弹体及过渡套的受力状态进行应力应变和两者之间相对位移的分析,比较出不同受力状态下外加扭矩的不同变化,奠定了弹带径向摩擦焊的理论基础。Based on the clip-model of frictional welding which for welding the body of the cannonball and the belt,the thee dimensional nonlinear FEM analysis system MARC is used to compare the contact and friction.The key is to analyze the stress and strain between the body of the cannonball and the transition-cover and their displaeements,It compares the changes in the different situations and establishes the theoretical foundation of the frictional welding.
