宽浅吃水船型单舱空爆动响应特性分析

Analysis of the dynamic response characteristics of single cabin air explosion of a wide and shallow draft ship type

冲击动响应是进行舰载设备抗冲击评估的重要输入。本文采用流固多场耦合数值仿真模拟宽浅吃水船型遭受空爆打击,计算距爆点不同距离位置处的冲击动响应并转化为冲击环境,得到空爆打击下宽浅吃水船型动响应的衰减规律,研究结果可为舰载设备抗冲击设计提供载荷输入,同时可为宽浅吃水船型总布置设计提供参考。

The dynamic response of ship impact is an important input for the impact resistance evaluation of shipborne equipment.In this paper,fluid-solid multi-field coupling numerical simulation is used to simulate the impact of a ship with wide and shallow draft under air explosion,and the dynamic impact response at different distances from the explosion point is calculated and converted into the impact environment,and the attenuation law of the dynamic response of a ship with wide and shallow draft under air explosion is obtained.The research results can provide load input for the impact resistance design of shipboard equipment.At the same time,it can provide reference for the general layout design of wide and shallow draft ship type.
