可拆卸式船桥的碰撞防护装置研究

A Study on the Detachable Protective Device against Ship-bridge Collision

文章借助ANSYS/LS-DYNA软件对船与防护装置之间的碰撞进行动态仿真模拟,研究了碰撞过程中撞击船与防护装置之间碰撞力的变化、结构的损伤变形和能量转换等内容。在碰撞损伤后损毁的构件可以拆卸更换,未损坏部分可继续服役使用,提高了船桥结构的耐冲击性能,对提高船桥碰撞性能有一定指导性意义。

On the basis of making a dynamic simulation of the collision between the ship and the protective device with the help of the software ANSYS/LS-DYNA, this article studies the collision force, structural damage deformation as well as energy conversion in collision. It arrives at the conclusion that the undamaged portion is detachable and the undamaged parts continue to be in service. It is of certain guidance meaning to the improvement of impact resistance of the ship-bridge structure.
