摘要
为研究串联战斗部前级装药对后级随进战斗部的影响,验证在现有导弹战斗部前端加装环形聚能装药的可行性,采用ANSYS/LS-DYNA软件进行了环形切割器对随进战斗部影响的数值仿真,在不同的前后级距离条件下,得到了随进战斗部的加速度、速度、位移变化和随进战斗部壳体和装药的最大应力值及其所在位置;仿真结果表明,在串联战斗部前后级相对静止时,不同间距条件下,环形切割器爆炸后形成的冲击波对随进战斗部加速度、速度、位移及壳体和装药的压力影响是不同的。
To study the influence of the tandem warhead＇s front charge to following warhead and verify the feasibility of installing annular shaped charge in the front of active missile＇s warhead, the annular cutter＇s influence to following warhead was simulated by ANSYS/LS-DYNA. The date of acceleration, velocity and displacement, the max stress of following warhead＇s shell, charge and their place were obtained in different distance between front charge and following warhead. Simulation results showed when following warhead was relating rest to front charge, the shock wave of annular cutter affected following warhead＇s acceleration, velocity, displacement and pressure of shell and charge, differently in different distance
