【摘要】 采用大型通用有限元软件MSC.DYTRAN,对某型水面舰船全船结构在水下爆炸冲击波载荷作用下的动态响应进行了数值模拟。分别从结构的变形损伤形式、能量吸收和冲击环境等几个方面研究了舰船结构在水下爆炸载荷作用下的破坏机理和响应特征。更多还原

【Abstract】 The dynamical response of ship structures subjected to underwater explosion shock waves is a mechanical problem which must be taken into account in engineering design of anti-shock ship structures. The dynamical response of a surface war ship has been simulated with the code MSC.DYTRAN. The dynamical response characteristics of the ship is studied through the structural damage deformation, energy absorption by ship components and the shock environments factors.更多还原
