摘要:
为探寻立方形钨破片着靶姿态对其穿甲效应的影响规律，采用ANSYS/LS-DYNA有限元软件和战斗部地面静爆试验相结合的方法，研究了破片以不同姿态正、斜撞击靶板时，破片的剩余速度、剩余动能和靶板损伤面积的变化规律。结果表明：正撞击时，不同姿态下破片剩余速度和靶板损伤面积相差较小，破片剩余动能变化稍大；斜撞击时，不同姿态下的3种参数与着角θ变化规律基本一致，面着靶靶板损伤面积最小，尖角着靶破片剩余速度和剩余动能最高，跳飞角度更大。研究结果对破片式杀伤战斗部设计和毁伤威力评估具有重要的参考意义。
Abstract:
In order to examine the effect of yaw angle of cubic tungsten fragment on its penetrating performance,ba sing on ANSYS/LS-DYNA numerical simulation and warhead static explosion test, residual velocity, residual kinetic energy and target damage area of fragment were researched, in condition of different fragment yaw angle and target angle. Results shows that, under vertical impact condition, at different fragment yaw angle, the residual velocity of the fragment and the damage area of the target change slightly, while the residual kinetic energy varies significantly; under crossed impact condition, at different fragment yaw angle, the three kinds of parameters follow almost the same trend. The target damage area is minimum under face impact; the residual velocity, residual kinetic energy, and the ricochet angle are maximum under tip impact. The research results will have an important reference to fragmentation warhead design and damage evaluation.
