摘　　要：为分析环形切割型串联战斗部对前级口径及自身初始姿态的适应性,开展了战斗部对目标作用的数值模拟研究。基于有限元分析软件LS-DYNA完全重启动技术,对不同口径前级和不同战斗部初始姿态下,后级弹体的随进侵彻过程进行数值计算分析。结果表明:前级口径对后级弹体的剩余速度和姿态影响较大,且趋势确定;但战斗部初始姿态对后级弹体的剩余速度和姿态影响很小,且趋势不确定;靶板失效形式可能是一个较重要的影响因素,值得进一步研究。The effect of tandem warhead on the target is numerically simulated and studied to analyze the adaptivity of tandem warhead to the calibers of travelling projectile and its initial attitude.The penetration processes of travelling projectile in the case of the calibers of precursor charge and the diferent initial attitudes of tandem warhead are calculated and analyzed based on the full restart technology of finite element analysis software LS-DYNA.The analysis result shows that the caliber of precursor charge has certain and appreciable effects on the residual velocity and attitude of travelling projectile,while the initial attitude of the rear warhead has little effect on them.And it is worthwhile to further study the effects of failure of targets.
