摘　　要：利用ANSYS/LS-DYNA软件,数值模拟了侵彻弹打击目标时圆柱形传爆结构和半球形传爆结构对主装药尾部的动力响应过程,得出了在两种不同结构影响下主装药尾部典型位置的力学响应曲线,比较两种结构对主装药的力学影响。结果表明半球形传爆结构对主装药具有更好的力学响应特性,仿真结果为侵彻弹传爆结构的设计提供了依据。By use of ANSYS/LS-DYNA, the dynamic response of main charge around the cylindrical and hemisphere booster charge structure in penetrating projectile was simulated individually, the dynamic response of six observation points on tail-end of main charge were calculated, and the effect of two booster charge structure were compared. It showed that the hemisphere structure has better performance than the cylindrical structure for the dynamic response of main charge, the study is useful for the design of booster charge structure.
