采用非线性动力分析软件Autodyn对装有随进子弹攻坚战斗部的飞行及爆炸过程进行了仿真计算,模拟了攻坚战斗部从着靶爆炸到子弹随进的初期过程,并着重对战斗部爆炸后产生的过载对随进子弹的飞行速度、飞行姿态、结构强度等状态的影响进行了仿真计算。得到了关于随进子弹在受过载作用前后的状态数据,并将仿真结果与某型号研制试验结果进行了比对分析。

A simulation calculation for the flight and explosion of the following-on warhead by the nonlinear dynamic software "Autodyn" was conducted, the initial process in which the warhead detonates and submunition follow-on process target was simulated, and the simulation calculation of the effect of overload caused by warhead detonation on flight velocity, flight attitude and structure strength was performed. The data of the follow-on submunition before and after overload were obtained, and the compare and analysis between the simulation result and test result for a certain version were completed.
