导弹遇靶碰撞的过载仿真分析

Overload Simulation and Analysis for Missile Impacting Target Drone

通过LS-DYNA显式动力学商业软件对导弹遇靶的几种典型状态进行模拟,用简化模型分析了导弹和靶机碰撞时头部的过载情况。结果表明:最大过载并非发生在碰撞初始时刻,而是在碰撞进行到一定程度时;随碰撞时弹轴与靶机轴夹角减小,最大过载减小。

Several typical cases when missile impacting target drone are simulated by using LS-DY- NA explicit dynamic commercial software, and the overload states of warhead when impact are analyzed with simplified model. Results indicate that the maximum overload occurs after a period time of impact not at the first time of impact, the maximum overload decreases with the axial angle between missile and target drone decreases.
