摘    要:提出了一种理论分析的方法,对预应力切削、磨削加工时所形成的表面残余应力进行定量分析.利用热弹塑性力学理论和有限元方法,从理论上计算已加工表面残余应力,讨论预应力加工条件对加工表面残余应力的影响,从而为表面残余应力的控制提供了理论依据。

关 键 词:残余应力  金属切削  预应力加工

Abstract:A theoretical method to analyse the residual stress in machined surfacewhen pre-stressed machining is presented. By means of thermal elasto-plastic finiteelement method(FEM),the residual stress in machined surface is obtained,andthe discussion on how the machining conditions influence the residual stress is given.Therefore,the theory base is provided for controlling the residual stress in machined surface.
Keywords:s: residual stress  metal cutting  grinding  surface layers  elastic-plastic analysis  finite element methods/pre-stressed  pre-stressed machining
