预制破片侵彻均质装甲钢的极限穿透速度

摘要

In this study,we at first made a mechanical analysis of the process of the prefabricated fragment penetrating fully the homogeneous armor plate using theoretical calculation and experimental study,and derived the penetration velocity respectively for three shapes of prefabricated fragments.Then,by combining live testing with simulation,we obtained this penetration velocity and had it compared with the theoretical calculation results,thereby arriving at the error between them and coming out with the revised coefficient for the critical penetration velocity.%通过对预制破片侵彻均质装甲钢的过程进行受力分析,推导预制破片极限穿透速度的计算公式,分别对3种形状规则预制破片的极限穿透速度进行理论计算,并通过实弹驱动试验和弹道枪模拟复核试验测得极限穿透速度与理论计算结果相对比,得出理论计算结果与试验结果的误差,通过数据分析处理给出计算公式的修正系数.
