| 摘 要： | 高速、小余量、硬车削是轴承淬硬钢加工的重要发展方向。为了研究小进给条件下轴承淬硬钢硬车加工后表层残余应力的分布问题,采用二维有限元方法对轴承淬硬钢AISI 52100硬车加工过程进行了仿真,获得了加工后材料表层残余应力。基于Konti Cut用户子程序对稳态切削过程进行建模,并对加工后的表面残余应力进行了预测。通过不同加工参数下的残余应力仿真与实验对比,得出仿真与实验预测趋势基本一致的结论,在工件表层0.02～0.06mm以上形成了较大数值的残余压应力。

| Abstract: | High-speed,small feed rate and hard turning is an important tendency in the machining of bearing steel.In order to investigate the residual stress after hard turning under a small feed rate condition,a 2D FEM simulation of AISI 52100 hard turning processes was carried out and the residual stress was obtained.Based on the user subroutine named Konti-Cut,the steady state of the cutting process was simulated and the cutting forces and residual stresses in this time were investigated.The residual stresses distribution predicted by the FEM model showed good consistency with experimental data.In addition,a relatively large compressive residual stress was formed in the depth of 0.02~0.06 mm under the machined surface. |
