作者通过试验建立了辊压产生的残余应力场模式、最大残余压应力与其影响深度间的定量关系以及残余应力松弛后的最终残余应力场。根据作者提出的应力场强法来分析最终残余应力场对疲劳寿命的影响。
Through experiments, the authors established the residual stress field mode, the quantitative relationship between the maximum residual compressive stress and its influence depth and the final residual stress field after residual stress relaxation. According to the authors proposed stress field method to analyze the final residual stress field on the fatigue life.
