摘　　要：建立舰船三维有限元模型,采用数值仿真方法计算舰船总体在水下爆炸载荷作用下的动响应,讨论船体主要构件破坏模式以及舰船鞭状运动对船体总纵强度的影响,总结舰船总体在冲击波阶段与气泡脉动阶段舰船毁伤模式及规律。A three-dimensional finite element model of a whole ship was established to simulate numerically the dynamic responses of the overall ship under underwater explosion.In this way,the damage mode of the main structure was deeply discussed and the influence of the ship whipping to the ship longitudinal strength was analyzed as well.The damage mode and rules of the whole ship in shock wave phase and bubble impulse phase were summarized.

关 键 词：舰船总体 冲击波 气泡脉动 毁伤模式
