破甲弹着靶姿态对破甲效应是有影响的.本文从碰撞的基本理论出发,研究了弹在着靶过程中运动姿态的变化,讨论了转动的存在和转动产生的原因——碰撞冲量矩以及影响弹转动的诸因素(弹头部着靶点的位置,弹与靶的恢复系数,弹绕着靶点的转动惯量等).同时还探讨了弹的何种运动姿态对破甲有利.这些分析对弹体方案设计,控制弹的着靶姿态和提高破甲效应是有意义的. The target of the projectile has influence on the armor effect.This paper starts from the basic theory of collision and studies the change of the attitude of the projectile in the course of the target, discusses the existence of the rotation and the reason of the rotation - collision impulse Moment and the factors that affect the rotation of the projectile (the position of the target of the projectile, the recovery coefficient of the projectile and the target, the moment of inertia that bounce around the target, etc.). These analyzes make sense for the projectile design, controlling the attitude of the projectile and improving the armor effect.
