摘要

摘要本文的目的是评估残余应力对滑动支座损伤的影响。为了量化残余应力，选择了使用SINT MTS 3000钻机的钻孔方法。在分析有限元数值模拟结果的基础上，确定了张量玫瑰花结的应用区域。对一个未使用的滑动支架和另一个滑动支架进行了实验测量，该滑动支架在目前的运行中完成了约9.106周。最后，对选定位置的残余应力测量值进行了分析。

The Assessment of the Residual Stresses Influence on Generation of the Infringement in Shape-Complex Supporting Members

Abstract The aim of the paper is to assess the effect of residual stresses on the damage of the slide bearer. To quantify the residual stresses, the drilling method using SINT MTS 3000 drilling machine was chosen. The tensometric rosette application areas were determined based on the analysis of the results obtained by numerical modeling using the finite element method. Experimental measurement was performed on one unused slide bearer and on the other one, which during its present operation had completed about 9.106cycles. At the end of the paper, the analysis of the measured residual stress values in chosen locations is presented.
