摘　　要：以某多管火箭炮贮运箱易碎盖为对象,建立了火箭弹和易碎盖两种材料的有限元模型,利用ANSYS/LS-DYNA软件进行瞬态动力学分析,计算了火箭弹碰撞易碎盖的全过程,得到了引信的应力应变以及易碎盖碎片速度、位移曲线。数值计算结果与实验效据对比,取得良好的一致性,研究表明,该方法为实弹射击试验研究提供一定的理论依据。The models of finite element analysis for a rocket projectile and a frangible cap are founded with ANSYS/LS- DYNA software.Transient dynamic analyses of the models are computed.The impacting process of the rocket projec- tile and the frangible cap are described.The stress and the strain of the fuze,and the velocity and the displacement of the frangible cap,are obtained.The computed results are in good agreement with those of the experimental data.This research works also show that the method presented here can provide theoretical guidance for the study area.
