利用ANSYS/LS-DYNA有限元分析软件,对船桥碰撞进行了数值模拟,分析了船身刚度对最大撞击力的影响,讨论了不同水位、不同角度以及船头不同碰撞部位对船撞力的影响,研究结果表明:船身刚度变化对撞击力的影响显著,需讨论确定,船头鼻艏直接撞击承台的撞击力比船尖首先撞击承台时的大,实际中应考虑不同碰撞部位的影响。
The impact of the ship’s hull stiffness on the maximum impact force is analyzed by ANSYS / LS-DYNA finite element analysis software. The effects of different water level, different angles and different collision positions on the ship’s impact force are discussed The results show that the impact of hull stiffness variation on impact force is significant. It is necessary to discuss and confirm that the impact force of bow nose bilge directly impacting the cap should be larger than that when the ship’s tip first hit the cap. In practice, Impact.
