摘　　要：筒形件的错距旋压是一个非常复杂的塑性变形过程 ,在生产实践中 ,常伴有旋压缺陷的产生。本文采用三维弹塑性有限元仿真的方法 ,对旋压变形过程中的韧性损伤、不贴芯模、隆起等典型缺陷的起因进行研究 ,并提出相应的预防措施 。Stagger spinning of tube parts is a very complicated plastic forming process. In real production, spinning defects are produced usually accompanying the production. In this paper, the reason of some typical defects of tube stagger spinning is studied by a method of three dimension elastic\|plastic finite element (FEM) simulation. This will be very helpful in directing the production of spinning parts in theory.
