摘　　要：简要介绍了薄壁不锈钢管环压接头的成形工艺,以ANSYS有限元分析软件中的LS-DYNA模块为平台,运用有限元动态显式和静态隐式方法,模拟了薄壁不锈钢管环压接头的承口成形过程。分析成形过程中管件的轴向尺寸变化,卸载完成后管件的回弹现象,以及成形过程中产生的应力集中现象。通过分析其变形过程确定管坯零件和相应模具的补偿尺寸,以及工艺流程中的注意事项。研究结果能有效的指导薄壁不锈钢管环压接头承口成形的模具设计和加工工艺的优化,极大缩短了产品开发和模具设计周期。It briefly introduced the forming process of thin-walled stainless steel tube ring compression fittings,based on LSDYNA module of finite element analysis software ANSYS as the platform,and the process of thin-walled stainless steel tube ring compression fittings was illustrated with explicit algorithms and implicit algorithms of LS-DYNA. Through analysis of forming process of tube axial dimensions,tube spring backs after the uninstalling is completed,and the stress concentration is produced in the process to determine the size of tube and molds for compensation,as well as the considerations in the process.The result is the effective guidance foe the moulds design and optimization of the thin-walled stainless steel tube ring compression fittings machining process,which greatly shortens the cycle of product development and mould design.
