摘　　要：利用有限元分析计算方法分别对爆炸网络控制定向战斗部和中心起爆战斗部装药驱动破片过程进行了研究,得到该过程的动画演示过程和各种相关数据。通过对数值模拟数据的处理,得到爆炸网络控制定向战斗部破片速度和数目的分布规律以及爆炸网络控制定向战斗部相对于中心起爆战斗部在增益区内的破片速度增益、数目增益和能量增益结果。The course of fragments droving by explosives in aimed warhead controlled by detonating meshwork and ordinary fragmentation warhead was studied by means of numerical simulation, and dynamic picture of this course and some interrelated data were obtained with the help of the data processing of numerical simulation results, the velocity and density distribution of fragments about aimed warhead controlled by detonating meshwork and the increases of velocity, consistency and kinetic energy of fragments about aimed warhead controlled by detonating meshwork relative to ordinary fragmentation warhead were obtained.
