引言 按照常规理论,投射物对目标的致伤效果,以投射物动能的大小来衡量,由此形成了“能量标准”。武器弹药设计非常重视弹头的终点动能,并利用弹头初速、断面比重、弹形系数的变化来改变弹头的终点动能。 近年来,终点弹道学研究取得了很大的进展。对投射物影响目标致伤效果的因素有了更深的认识,即在终点动能相当的情况下,投射物质量和速度匹配不同、材质不同、结构不同,对目标的致伤效果不同。
Introduction According to the conventional theory, the projectile's effect on the target is measured by the size of projectile's kinetic energy, thus forming an “energy standard.” Weaponry and ammunition design attaches great importance to the terminal kinetic energy of the bullet, and changes the end kinetic energy of the bullet by utilizing the change of the initial velocity of warhead, the specific gravity of the cross section and the spring coefficient. In recent years, end point ballistics has made great progress. The impact of the projectile on the target of injury has a deeper understanding of the effect, that is kinetic energy at the end of the case, the projectile mass and speed to match the different materials, different structures, different effects on the target of injury.
