中小型交通船耐撞性能研究

Research on Crashworthiness of Small and Medium-sized Traffic Boats

以2200t级交通船为研究对象,建立撞击船、被撞船以及水域有限元模型,采用附加质量法研究不同撞击位置、不同撞击角度和不同撞击速度对该船耐撞性能的影响,获得了不同方案下的运动状态以及损伤变形、碰撞速度和碰撞力等动态结构响应。所获结果可为交通船在不可避免地发生碰撞时提供操船建议,对于提高交通船的结构强度具有重要的参考意义。

Taking the 2,200-ton traffic boat as a research focus,the finite element model of the colliding ship,the collided ship and the water area is established.The impact of different collision positions,different collision angles and different collision speeds on crashworthiness of the boat is studied by the additional mass method.The dynamic state under different schemes and the dynamic structural response such as damage deformation,collision speed and collision force are obtained.The obtained results can provide the traffic boat with maneuvering suggestions for inevitable collision situation,which has significant reference for improving the structural strength of the traffic boat.
