摘　　要：为实现陶瓷微粒限定范围内低附带毁伤效果,将炸药与陶瓷微粒混合构成新型复合装药结构。在相同结构与药量的情况下,对非金属战斗部壳体壁厚进行优化设计,设定3种不同壳体壁厚,采用LS-DYNA软件模拟仿真外加试验验证的方法得到壳体壁厚对陶瓷球初速的影响规律。结果表明:同种装药结构中,壳体壁厚为4 mm、陶瓷球初速在1 100m/s左右时,对比发现低附带毁伤效果最好;模拟仿真与试验结果规律基本一致。To achieve low collateral damage effect of ceramic particles within the limited range, the new composite charging structure was constituted with explosives mixed with ceramic particles. Through optimizing the wall thickness of non- metal warhead under the same structure and charge, three different case wall thickness was set. The LS-DYNA software simulation methods conbined with experiment were applied to verify the influence of wall thickness on the initial velocity of ceramic ball. The results show that under the same kind of charge structure, low collateral damage achieves the best with wall thickness of 4mm, initial velocity of ceramic ball at about 1100m/s. The simulation results agree well with experimental results.
