摘要
为了研究波浪力对于柔性浮式防撞系统拦阻效能的影响,本文提出了分步处理波浪力的方法,进行了撞击过程的模拟计算研究。文中基于势流理论运用ansys_aqwa软件,求得了不同波浪入射角及不同相位下结构物的波浪力。在模拟船舶撞击系统的过程中,将计算较为复杂的波浪力,转化为运用处理不同时刻波浪入射角和相位角的问题进行连续分析计算。研究表明,微段时间波浪力计算方法可以用于柔性浮式防撞系统的运动分析,船舶撞击过程中不能忽略波浪力的影响。
In order to study the wave force for effect of The Flexible Floating Collision-Prevention System（FFSCS）, step by step computational method of the wave force is presented in this paper, numerical simulation is carried out for the collision process. Based on potential flow theory, the ansys_aqwa software is used to obtain the wave forces of different incident angles and different phase angles. In the process of simulation of the ship collision, the calculation of the wave force is more complex. This paper use the method, which deal with different wave incident angles and different wave phase angles at Micro times, to calculate continuously. Comparative analysis of the results show that, the effect of different waves for the collision process is different. In the collision process, the influence of the wave force can＇t be neglected.
