摘　　要：采用非线性有限元软件LS-DYNA,模拟剪切式爆炸螺栓中炸药爆炸及爆炸冲击波对爆炸螺栓盒中的冲击破坏作用,校核盒盖的动强度。计算结果表明,盒盖变形、破坏形式、压力峰值和脉宽都与试验结果吻合较好。根据对计算结果的分析,提出爆炸螺栓盒的三种改进办法,并通过分析计算确定了最佳方案。The process of PETN exploding and its effect to the explosive bolt box are simulated using LS-Dyna which is nonlinear dynamic finite element analysis software. The results of simulation, such as the pressure in box and deformation of the cover, agree with experiment results. Through the analysis and the above simulation, three design methods were put forward to optimize the explosive bolt box.
