摘　　要：为使模拟弹爆炸驱动后形成大小均匀、飞散合理的破片群,对模拟弹弹体采用预制破片技术。利用LS-DYNA有限元计算程序和破片初速经验理论公式,得到破片飞散的初速、破片沿着轴向的速度分布和破片向前、向后的飞散角度,并设计模拟弹进行靶场试验验证。结果表明:数值模拟结果与试验结果近似一致,且采用预制破片技术对弹体改性后形成的破片较均匀。In order to improve size uniformity and reasonable scattering fragment cluster,the preformed fragment technology was introduced to bomb body material. Initial velocity,velocity distribution along axial direction and scattering angle were calculated by LS-DYNA program and experienced formula. Simulation projectile was designed and target test was used to validate. The test shows that results of numerical calculation and test are almost the same,the preformed fragment technology can improve the fragment cluster’s uniformity.
