摘要
为保证舰船安全性,提高舰船生命力,舰船在水下爆炸冲击波载荷作用下动态响应,是船舶结构动力学研究的重要课题之一。采用MSC.DYTRAN有限元程序,运用数值仿真技术研究了某型水面舰船在水下爆炸冲击波载荷作用下的动态响应。分别从结构变形损伤、应力应变响应、变形能吸收和冲击环境等几个方面研究了舰船结构在水下爆炸冲击波载荷作用下的响应特性。
For the safety and vitality of a warship, the dynamic response under the action of underwater explosion (UNDEX) shock waves is an important research aspect in the field of ship structural dynamics. In this paper, the dynamic response of a surface warship subjected to UNDEX loading is analyzed with respects to the damage of ship structural deflection, the stress-strain response, the absorption of distortional energy and the impact environment by employing the MSC. DYTRAN code.
