非接触水下爆炸舰船结构响应分析

摘要

It is inevitable that battle ship and operating ship suffer shock from underwater explosion as well as shipman and equipments. Realizing the shock environment of ship can direct the safety design of shipman and equipments. Constructed the FEM model of surface ship with Abaqus and analyzed the shock environment while to explode 1 000 kg TNT at distance of 60 m from ship horizontally and at depth of 60 m.The shock environments of ship have logical values and right orderliness. The results can apply to design in safety design of shipman and equipments.%军舰以及实施水下爆破任务的舰船不可避免要遭受水下装药爆炸的冲击载荷,舰船上人员与设备要承受由此带来的强冲击.确定舰船遭受水下爆炸引起的冲击环境,对舰船人员和设备的防护都有指导作用.针对3 000 t级水面舰船,应用Abaqus有限元软件建立舰船有限元模型,计算了距舰船水平距离60 m,装药水深60 m,1000kgTNT当量装药水下爆炸,舰船的冲击环境.得到的舰船典型部位结构的速度响应数值合理,规律正确,得到的舰船冲击环境可以指导舰船人员及设备的冲击防护设计.
