为了提高金属零件的疲劳寿命，特别是在航空航天工业中，喷丸被广泛应用。需要先进的数值算法和方法来估算喷丸产生的残余应力。本文描述了一种模拟喷丸过程和估算表层残余应力场的分析模型。在这个合理、方便、简单的模型中，没有使用经验关系，并且考虑了射击速度的影响。利用试验数据对该模型进行了验证，取得了很好的效果。关键词：喷丸、残余应力、分析
To improve the fatigue life of metallic com- ponents,especially in aerospace industry,shot peening is widely used. There is a demand for the advancement of numerical algorithms and methodologies for the estima- tion of residual stresses due to shot peening. This paper describes an analytical model to simulate the shot peen- ing process and to estimate the residual stress field in the surface layer. In this reasonable, convenient, and simple model, no empirical relation is used, and the effects of shot velocity are included. The results of validation of this model against the test data are very good. keyword: Shot-peening, Residual Stress, Analytical
