摘　　要：在 ANSYS基础上开发了可以模拟管材滚压剪切过程的应用软件 ,利用单元死活技术对管材的切断问题进行了模拟。根据有限元计算结果分析了各种因素对切口金属流动的响影规律 ,通过实验验证了用有限元法进行管材滚压剪切过程模拟的可靠性和有效性 ,为确定合理的刀具和工艺参数提供了理论依据。The process of roll-cutting tubes was simulated on basis of the principle of large deformation elastic-plastic FEM by ANSYS program and killing element technique. The distribution of strain and stress, for all material points at any deformation zones can be obtained at any instant during whole roll-cutting process FEM. Some factors affecting roll-cutting quality are brought forward.The reliability and validity of simulating the process of roll-cutting tubes is verified by experiment.
