摘　　要：为了满足低附带战斗部的毁伤效果,将炸药与破片混合形成新型混合装药模式。在混合装药模式中,为了研究不同装药结构对破片初速的影响特性,设计了3种不同装药结构并进行数值模拟和试验;对比发现,数值模拟与试验结果规律吻合,破片的初速与装药结构有一定的关系。根据试验数据拟合了3种不同装药结构中破片最大速度曲线对比图,通过分析得出:不同装药结构中,炸药与破片分层越多,爆轰瞬间,相邻炸药所产生爆轰效果会发生叠加,爆轰波对破片的驱动效果会增强,则破片的初速也就越大。In order to fulfill destroy capability of low collateral damage warhead,the explosives mixes with particles to constitute new compound charge. In the case of compound charge,to have the researcher of different charge structure on initial velocity impact characteristics of particles,three different charge structures of PLA and simulated and tested. By comparison,it is that the numerical simulation consistents with the experimental results.Initial velocity of particles is the certain relationship with the charge structure. According to the experimental data fitted the maximum speed comparison chart of particles in three different charge structures,the analysis is obtained the analysis that the more layers of explosives and particles,the detonation wave driven particles better because of adjacent explosives detonation effect will occur superimposed at the moment of detonation instantly. So the initial velocity of particles will be greater.
