摘　　要：激光冲击成形(Laser Shock Forming-LSF)是利用激光诱导高幅冲击波的力学效应,使板料产生塑性变形的一种新技术。根据激光冲击过程中爆轰波的形成传播以及点爆炸成形的基本理论,依据冲击波在凝聚介质中的传播规律,建立了激光冲击成形过程中冲击力的理论模型,得出激光冲击成形系统中各部件之间力的作用关系,能为激光冲击成形提供计算方法和优化依据,具有十分重要的研究意义。Laser Shock Forming （LSF） is a new technology of sheet plastic forming which utilizes impulse wave＇s mechanical effect induces by laser device. Based on the transmission of detonation wave and the fundamental theory of point - source explosion forming, based on the propagation law of shock wave spread in the condensed medium. Built the mechanical effect＇s theoretical model during the laser shock forming and come to a conclusion of the effects of forces between the system of laser shock forming. This conclusion can provide the computing method and optimization on laser shock rotating and has fundamental re,arch significance.
