摘要:
基于显式动力分析软件LS-DYNA，利用SPH方法对圆柱型装药爆轰问题进行了数值模拟，计算结果表明SPH方法可以准确模拟炸药爆轰及产物膨胀飞散过程。在此基础上建立了圆柱型装药与钢板接触爆炸的三维数值计算模型，分析了接触爆炸荷载作用下钢板的动力响应问题，模拟结果直观显示了接触爆炸作用下钢板发生层裂和穿孔破坏的过程；进行了等比例圆柱型装药与钢板接触爆炸试验，数值计算结果与试验结果符合较好，说明SPH方法可以准确描述爆炸作用下结构的动力响应。
Abstract:
Based on the finite element analysis software LS-DYNA, the detonation of cylinder charge was analyzed by the SPH method. The simulation results show that the SPH method could simulate the process of detonation and the process of dispersion of the detonation products efficiently. The 3D model of the cylinder charge and the steel plate in contact with the explosive load was set up, and the dynamic response of the steel plate was analyzed. The results show the destruction process of the slabbing and the punching of the steel plate explicitly. Samesized experiment of the steel plate under the contact explosion load was performed. The results of the simulation and the experiment data are in good agreement, indicating that the SPH method can accurately describe the explosion and the dynamic responses of the structure under the explosion load.
