摘要: 为了研究镁合金在激光冲击载荷作用下残余应力场的特征,采用实验测试和有限元分析的方法对激光冲击区的残余应力进行了研究.试验中使用Nd:glass脉冲激光对AM50镁合金表面进行冲击强化处理,当激光功率密度为3GW/cm2时,表面的残余压应力值高达-146MPa,残余压应力层深约0.8mm;用有限元分析软件ABAQUS对残余应力场进行数值计算,得到激光功率密度大于0.49GW/cm2时,将产生残余压应力,随着功率密度的增加,残余压应力值增加并趋于饱和;激光功率密度在1.95GW/cm2～3.06GW/cm2之间时,残余压应力值达到饱和.结果表明,实验测试数据与数值计算结果一致性较好,该结果可为激光冲击参量的优化提供理论依据.

Abstract: In order to study the characteristics of the residual stress field in the laser shocked area,the residual stress was studied with finite element analysis method.With a Nd: glass pulse laser shocking the surface of AM50 magnesium alloy in experiments,when the laser power density was about 3GW/cm2,the compressive residual stress on the surface of laser shocked area reached-146MPa,and the depth of the compressive residual stress layer was about 0.8mm.Numerical analysis was done with finite element software ABAQUS.The numerical analysis results showed that when the laser power density was over 0.49GW/cm2,there was compressive residual stress in the shocked area,as the laser power density increased,the residual compressive stress also increased and when the laser power density was between 1.95GW/cm2 and 3.06GW/cm2,the residual compressive stress reached saturation.The results show that the calculation results conforms to the experimental data,the numerical results can be used as theoretical basis for optimizing the process parameters in laser shock processing.
