| 摘 要： | 建立了平面应变状态下的正交切削模型,并基于热-弹塑性有限元理论和改进的Lagrange方法,利用有限元软件对切削过程和残余应力的获得过程进行模拟,得到了已加工表面残余应力的分布规律,以及刀具前角和刀刃圆弧半径对残余应力的影响规律。研究发现,残余应力的数值随着圆弧半径的增大而增大,随着刀具前角的增大而减小。本文的结论可为调整和控制残余应力、提高已加工表面质量提供指导。

| Abstract: | An orthogonal cutting model under plane strain condition is presented,and the cutting process is simulated by a commercial finite element software based on the thermal-elastic-plastic FEM theory and updated Lagrange method.The distributions of residual stresses in machined layer are obtained under different rake angles and tool edge nose radius according to the simulation results.The effects of tool rake angle and tool edge nose radius on residual stress distributions are investigated in the paper. |

| Keywords: | finite element method(FEM) residual stress tool rake angle tool edge nose radius |
