摘要
为了优化单兵破片战斗部的设计,用实验方法得到0.16 g钨球侵彻Ⅲ、Ⅳ级凯夫拉及2 mm厚LY12CZ硬铝板的极限穿透速度分别为729 m/s、746.2 m/s和379.3 m/s。用数值仿真方法得到0.16 g、0.2 g、0.25 g、0.3 g和0.35 g等不同质量的钨球侵彻2 mm厚的LY12CZ硬铝板的极限穿透速度分别380 m/s、363 m/s、355.5 m/s、337.5 m/s和333.5 m/s,根据比动能不变原理得到上述不同质量钨球侵彻Ⅲ、Ⅳ级凯夫拉的极限穿透速度。根据极限穿透速度-钨球质量关系可知单兵破片战斗部破片取0.2~0.25 g的钨球最为合适。
In order to optimize the design of single fragment warhead,the ultimate penetration velocities of 0.16 g tungsten balls penetrating classⅢ,ⅣKevlar and 2 mm thick LY12CZ hard aluminum target are respectively 729 m/s,746.2 m/s and 379.3 m/s by experiment.The ultimate penetration velocities of tungsten balls of different masses,such as 0.16 g,0.2 g,0.25 g,0.3 g and 0.35 g,penetrating 2mm thick LY12CZ hard aluminium plate are respectively 380 m/s,363 m/s,355.5 m/s,337.5 m/s and 333.5 m/s by numerical simulation and the ultimate penetration velocities of tungsten balls penetrating ClassⅢ,ⅣKevlar are calculated by the principle of specific kinetic energy invariance.According to the relation between the ultimate penetration velocities and the masses of tungsten balls,it can be concluded that the most suitable mass of the tungsten ball fragment is 0.2 g^0.25 g for single fragment warhead.
