半穿甲弹丸对加筋靶板侵彻的终点弹道的实验和理论研究

The experimental and theoretical research for end-point trajectory of warhead penetrating ribbings structural target

以舰船典型筋板结构为目标,设计了带加强筋的结构靶,并用模拟实验弹体,对单层带加强筋的结构靶进行了斜侵彻实验,通过天幕靶和高速运动分析系统的测量,得到了两种倾斜着靶条件下不同着靶位置的靶前、靶后弹道参数;通过对靶板破坏结果的分析,得到实验弹靶条件下加强筋结构靶的破坏模式。在现有弹丸侵彻均质靶板理论的基础上和一定假设条件下,得到弹丸对加筋结构靶侵彻的终点弹道理论计算模型,弹丸过靶后剩余速度的理论计算结果与实验结果基本一致。

According to the structure of aircraft carrier and existing anti-ship missile warhead, the structural target with ribbings and experimental semi-armor-piercing warhead were designed with geometer similar principle. The processes of warhead penetrating the ribbings structural and homogeneous targets were investigated experimentally in the shooting range, and the end-point trajectory parameters in hitting conditions and the breakage mode of target were gained. On the basis of the theory of warhead penetrating homogeneous target and with the some hypothesis, the theoretical calculation model for end-point trajectory of warhead penetrating ribbings structural target was found. The results by theoretical calculation to residual velocity of warhead were consistent with that by experimental test.
