【摘要】 对水下冲击载荷在多层结构中的传播规律进行了理论分析,根据分界面上的应力和速度连续性条件得到透射波强度的解析表达式。从理论分析可以看出,舰船结构的多层防护体系对于减少爆炸冲击的损伤具有重要的作用,防护结构的波阻抗越大,防护的效果越好,这种方法可应用于多层防护结构在远场爆炸冲击波作用下的毁伤或防护方面的预测。更多还原

【Abstract】 The promulgation of water impact wave in multilayer structure is analyzed theoretically.Theory expression of transmission wave intensity is gained based on stress and velocity continuity of interface.On the basis of theoretically analyzing,multilayer defense structure of warship has important effect to reduce the damage of explosive.The value of wave impedance is bigger,the defense effect is more effective.The method can be applied to the engineering prediction of the damage or safety of multilayer defends structure under forane explosive blast wave.更多还原
