半穿甲型舰炮弹药打击舰船舷侧毁伤效果数值仿真

半穿甲型舰炮弹药在命中舰船舷侧后发生爆炸，在爆炸过程中弹丸的侵彻动能和装药产生的爆炸冲击波会对舰船舷侧结构造成毁伤。分析舰船舷侧的结构特性和弹目交会情况，采用数值仿真方法构建仿真模型，分析半穿甲型舰炮弹药在靶前炸、靶中炸、穿靶炸等工况条件下对舰船舷侧的毁伤效果。结合实尺寸舱室模型试验结果对毁伤效果进行验证，预测在实际作战时弹药起爆点位置、末端着速对舰船舷侧毁伤结果的影响。

Numerical Simulation of Damage Effect on Ship Side under Strike of Semi-Armour-Piercing Ship Gun Ammunition

The semi-armour-piercing ship gun ammunition explodes after hitting the ship side, and the penetrating kinetic energy of the projectile and the explosion shock wave generated by the powder charge during the explosion cause the damage to the ship side structure. The structural characteristics of ship side and the simulation of ammunition-target encounter are analyzed, the simulation model is established with the numerical simulation method, and the damage effects of semi-armour-piercing ship gun ammunition on the ship side under the conditions of explosion in front of the target, explosion in the target, and explosion through the target are analyzed. Combined with the results of model test of real size compartment, the damage effects are verified, and the influence of detonation point location and terminal impact velocity of the ammunition in the actual combat on the damage results of ship side is predicted.
