摘　　要：利用Autodyn进行了破爆型串联随进攻坚战斗部爆炸场数值仿真,得到了装药的爆炸压力、速度和温度分布,获得了作用在随进子弹头部和子弹装药炸药内的爆炸响应冲击波压力-时间历程,得到了爆炸过载及其对随进后级的速度降。仿真结果表明,子弹装药炸药具有不被前级爆炸所殉爆的安定性和足够的随进速度,爆炸过载满足子弹引信解除保险要求。对比静爆实验结果,数值仿真与实验基本相吻合,这种方法可以为随进战斗部设计提供依据。Using Autodyn software,the explosive field of demolition-blast traveling hard structural tandem warhead was investigated by numerical simulation. The blast pressure,velocity and temperature distributions were gained. The response blast shock wave pressures varied against time of sub-munition fore-body and charge were calculated. The explosive overload and velocity drop-off of sub-munition were obtained. Simulation results show that sub-munition charge has sympathetic detonation security and enough traveling velocity,and explive overload can meet sub-munition fuze arming demand. Numerations agree with test results,which can support the base for this type warhead design.
