摘　　要：利用有限元软件对破爆型串联战斗部第一级装药爆轰对第二级随进子弹影响结果进行了数值模拟。分别计算了在不同后级子弹速度、不同前后级距离条件下的影响结果。获取了前级爆轰产物对后级子弹速度的影响结果以及前级爆轰产物作用于随进子弹及装药上的超压。该计算结果为破爆型串联战斗部结构设计有较大的参考价值。A three-dlmensional computational study of blast effect on traveling projectile of tandem warhead has been performed using finite element programme of LS-DYNA. Numerical simulation of different distance of two-stage and different initial velocity has been carried out. Overpressure and velocity drop of traveling projectile has been got based on different initial conditions. Essential analysis and conclusion has been derivated at last of the paper, and the computational result has high value to consult for TWPB design.
