离散杆对钢板的高速侵彻效应

Effects of Oblique Penetration on Plates by Rod

空空导弹可控离散杆战斗部爆炸后抛撒出一组细长杆条,这些高速飞散和旋转的杆条从不同的角度对目标物体进行高速侵彻穿透。本文主要通过建立合理的侵彻模型和计算方法,对细长杆条从不同角度侵彻靶板的过程进行数值仿真研究。研究结果表明,高速飞行的细长杆可以从不同角度穿透靶板,形成不同程度的毁伤,侵彻过程中呈现复杂的塑性应力波的传播,导致形成不规则的毁伤面和杆复杂变形状况。

The explosion of a controlled discrete rod warhead of an air-to-air missile throws slenderrods. These rods rotate and fly at a high speed from different angles to penetrate the target. This paper conducts numerical simulation of these penetration processes to a target board by the way of building reasonable penetration models and choosing suitable calculation methods. The simulation results show that slender-rods flying at high speed can penetrate and damage a target board from different degrees. In the course of penetration, the complicated propagation of the plastic stress waves leads to irregular areas and complex deformation of rods.
