Abstract

In this paper, analysis of influence of residual stresses in the surface layer of cylindrical friction pairs on the operational wear resistance index is carried out. Stresses of the first kind after application of combined machining are investigated. Combined machining is consecutive electromechanical machining and diamond burnishing. A formula for calculation of residual stresses originating in the surface layer after the combined machining is obtained. For computational convenience, a computer program calculating the residual stress parameter is written in Visual studio 2017 C#. The combined machining method creates a potential for improving performance indices due to creation of compressive residual stresses.

组合加工方式对圆柱摩擦副表面层残余应力值和特性影响的理论研究

摘要

本文分析了圆柱摩擦副表面层中的残余应力对工作耐磨性指数的影响。研究了组合加工后的第一类应力。组合加工是连续的机电加工和金刚石抛光。获得了用于在组合加工之后源自表面层的残余应力的计算公式。为方便计算，在Visual Studio 2017 C＃中编写了计算残余应力参数的计算机程序。由于产生了压缩残余应力，因此组合的加工方法具有改善性能指标的潜力。
