摘要
以某小型空空导弹打击直升机为背景,对空空导弹与目标相撞时的引信环境进行研究。利用ANSYS/LS-DYNA工具,对空空导弹在不同着速、不同碰击姿态下对直升机不同典型要害部位的碰撞情况进行数值模拟计算,对碰撞过程中应力波和过载在弹体内的传递,及其对引信系统的影响等动力学特性进行了探讨研究,为惯性敏感触发装置的强度校核、抗高过载防护以及对碰撞环境信息的正确判断提供参考。
The fuze environment of airborne missile impacting on helicopter target is researched.With the ANSYS/LS-DYNA software,the impact effect is simulated while the airborne missile impacted on the different typical key part of the helicopter at different speed and angle.The dynamics characteristic,for example,how the stress wave and acceleration transmitted and their influences on the fuze system,is researched.It offers reference for the intensity check,protection of the inertial sense device against the high acceleration and for making right judgement about the impact environment information.
