摘　　要：合理设置舰船缩比模型海上毁伤试验工况,有效考核舰船抗冲击性能和兵器毁伤效能的同时,减小舰船模型的毁伤程度。通过测量和分析模型在不同装药量和不同爆炸初始深度的爆炸载荷试验数据,确定爆源布放深度与表面反射及海底边界条件等对冲击波压力和气泡脉动影响的关系,为分析舰船冲击环境及水下非接触爆炸数值仿真数据输入提供思路。In order to set sea conditions of the ship scale model damage test properly,the damage degree of the ships model should be reduced when the ship shock resistance and weapon damage potency are assessed effectively. Experiment data shows that the explosions depth, surface reflection and undersea boundary conditions play role in the shock wave pressure and bubble-oscillation by loading under the different charge and explosion depth. This method can be applied to analyze shock environment on the ship and provide data input to the numerical simulation of noncontact underwater explosion.
