摘要
为研究激光冲击强化(LSP)过程中激光诱导冲击波的时空分布规律，在对比分析有限元仿真的基础上，探索采用光滑粒子流体动力学(SPH)对激光冲击强化的物理过程进行仿真，并设计了冲击波测试平台，对仿真结果进行了初步试验验证。结果表明，SPH模型演化物理过程明显，计算结果和试验结果相似度高，为激光冲击强化物理仿真提供了一种新的研究思路和方法。
Abstract
Propagation of detonation waves and space-time regularities of distribution in laser shock processing is investigated, a new numerical simulation model of laser shock processing (LSP) is established by smoothed particle hydrodynamics (SPH) in contrast to finite element simulation method, and verified by experiments. Results show that SPH model has obvious physical process and good similarity to experimental results, providing a new mean for laser shock processing.
