舰船舱室在遭遇反舰武器攻击时会受到高强度冲击波载荷对舷侧板的毁伤作用。对不同边界尺寸下的薄板在爆炸冲击载荷作用下的挠度变化的时间历程响应进行理论分析和数值模拟。根据板的弹塑性变形理论，通过能量法建立修正后的薄板在爆炸冲击载荷作用过程中的动态响应方程，并通过数值模拟建模仿真计算与理论计算值及试验值对比，验证在不同边界尺寸下该理论计算方法有较好的可靠性及精确度。
The Ship cabin would be subject to high-intensity shock wave load when it was attacked by anti-ship weapons, causing its side board damaged. The time course of the deflection of the thin plate in different boundary size under the impact load was researched by theoretical analysis and numerical simulation. According to the theory of elastic-plastic deformation of the thin plate, the dynamic response equation of the thin plate under the explosion impact load was established with method of energy, and the experimental value was compared with the result from numerical simulation as well as theoretical calculation. It proved that the theoretical calculation method has better reliability and accuracy in different boundary size.
