对船体板架结构在空中近场爆炸载荷作用下的破坏进行研究，根据爆轰波理论及气体膨胀理论计算出空中近场爆炸载荷，应用应力波及塑性动力学理论计算船体板架结构的变形，得到不同工况下板架的破口大小及挠度。通过算例进行验证，计算结果合理，可应用于舰船结构在空中近场爆炸冲击波作用下毁伤的估算，为舰船的安全防护设计提供了依据。
對船體闆架結構在空中近場爆炸載荷作用下的破壞進行研究，根據爆轟波理論及氣體膨脹理論計算齣空中近場爆炸載荷，應用應力波及塑性動力學理論計算船體闆架結構的變形，得到不同工況下闆架的破口大小及撓度。通過算例進行驗證，計算結果閤理，可應用于艦船結構在空中近場爆炸遲擊波作用下燬傷的估算，為艦船的安全防護設計提供瞭依據。

The ship plate frame crevasse under anti-ship missile battle assembly exploding is studied .Based on the theory of exploding wave and gas inflating ,the exploding load is computed .Based on the theory of stress wave and plastic dynamics ,the distortion of ship plate frame is calculated ,and the size and flexibility of crevasse under different working condition are obtained .The results are verified via simulation computation . It can be applied to estimate the damage of ship plate frame under anti-ship missile battle assembly exploding ,and to provide data for safety defending design of ship .
