摘要
为揭示曲轴感应淬火后残余应力的分布情况,采用有限元仿真与盲孔法相结合的方式对曲轴进行模拟和测试。结果表明:仿真与实测结果吻合度较高,曲轴经感应淬火后过渡圆角区域残余应力较大,其中在第一主轴颈处有最大值212 MPa。
In order to reveal the distribution of residual stress after induction hardening of crankshaft,the crankshaft was simulated and tested by the combination of finite element simulation and blind hole method. The results show that the agreement between the simulation and the measured results is high. The residual stress in the transition fillet region of the crankshaft after induction hardening is greater,and the maximum value at the first spindle neck is 212 MPa.
