摘要
为研究不同激光喷丸(LSP)工艺参数对强化效果的影响，以ISIGHT软件为平台，结合数值模拟软件ANSYS建立了激光喷丸参数化文件。采用多岛遗传算法对激光工艺参数进行优化，获得一组最佳参数组合。探讨了不同峰值压力及光斑半径对残余应力场及塑性变形的影响，结合实验对优化后激光参数下的塑性变形结果进行了验证。结果表明：模拟结果和实验结果一致性较好，所设计的优化方法可行，对今后的研究具有指导意义。
Abstract
In order to investigate the influence of different laser shot peening (LSP) parameters on the strengthening effect, the finite element software ANSYS integrated with ISIGHT was adopted to establish a LSP parameterized file. Multi-island genetic algorithm (MIGA) was applied to optimize the process parameters of LSP, and an optimal parameter combination was obtained. The effects of different LSP parameters on the residual stress field and plastic deformation of the treated surface were discussed. Good consistency can be found between the simulation and experimental results under the optimal process parameters, which indicated that the optimization approach was feasible, and some guidance for the future research was also pointed out.
