摘　　要：利用非线性动力学软件AUTODYN对球形及不同长径比圆柱形装药冲击波场及其传播过程进行数值模拟,探讨了长径比对圆柱形装药冲击波场的超压区分布影响规律,给出了柱形装药可与球形装药等效的临界距离计算公式;通过对不同形状装药对四边固定方形靶板冲击过程的数值计算,得到靶板中心点的挠度值,结果与试验吻合较好,本文结果可为柱形装药与球形装药等效计算、目标在不同形状装药爆炸冲击波作用下的动态响应问题及装药优化设计提供参考.To study the features of the blast wave field propagation process caused by spherical change or different columniform charges and the deformation of thin plane under impulsive loading, simulation has been carried out using AUTODYN software. The features of blast wave field and deformation of target were gained from simulation and analysis. On the other hand, the experiments was arranged to confirm the validity of the simulation model and the experimental results show that the simulation model is consistent with experiment. This research provides some reference for warhead optimized design and other similar problems.
