摘　　要：采用商用有限元软件MSC.Marc分析车轮残余应力测试试验的整个锯切试验过程,分析了锯切中每个测试点的应力、应变变化情况。通过比较仿真结果与工程试验测试结果,说明车轮锯切试验测试残余应力的可靠性。锯切的仿真分析为进一步研究车轮残余应力测试方法奠定了基础。The saw-cutting test process is simulated with the finite element commercial software MSC. Marc, The variations of the stress and strain condition at each test point during the saw-cutting process are studied. Comparison between FEM simulated results and engineering test results shows that to measure residual stress by saw-cutting test is feasible and reliable. The results of simulation analysis lay a good foundation for further study on measuring the residual stress of railway wheel.
