摘要
在研究船-桥墩防护装置碰撞机理的基础上,结合实例阐述了船舶与防护装置碰撞的有限元模型的建立过程,详细叙述了单元尺寸的控制、材料模型和失效准则的选取、接触及摩擦力的定义等碰撞分析中需要考虑的问题.最后利用ANSYS/LS-DYNA对建立的碰撞模型进行了全程有限元仿真模拟,得出了一系列有意义的结论.
Based on the solving technique of explicit non-linear finite element method and the mechanism in ship-anti-collision equipment collision, this thesis recites the process of building a reasonable FEA model and develops numerical simulation to the collision process of a ship and an anti-collision equipment. On the basis of numerical simulation, some results, such as structural deformation and collision force in the collision region、the change in the kinetic energy of ship、the movement of the ship and so on, are achieved.
