着靶姿态对半穿甲战斗部穿甲过程的影响

利用LS-DYNA对半穿甲战斗部着靶时不同着角和攻角对穿甲过程的影响进行研究,进行了在着靶速度为2Ma,靶厚为50mm,着角、攻角分别为0°、10°、20°条件下的侵彻数值模拟.仿真结果证明,着靶时着角、攻角均对穿甲过程产生影响,且攻角的影响更大.

Influence of Hitting Attitude in Armor-Piercing Process

The influence of the landing angle and attacking angle for the penetrating process was studied by LS-DYNA when the semi armor piercing warhead.The simulation of penetration was carried out when the landing velocity is 2 Ma, the thickness of target is 50 mm, and the attacking angle is 0, 10 and 20 degree.The results of simulation indicate that the landing angle and attacking angle both have influence on the penetrating process and the attacking angle is larger.
