摘要
本文介绍了一种频、时域杂交法 ,用于预报柔性连接多浮体在波浪中的运动。其中采用三维频域法适时求解浮体的水动力系数 ,在时域内求解浮体的运动方程 ,可同时求解非线性锚链力、连接器受力和护舷受力。利用本方法预报了柔性连接的“口”字形六浮体系统在波浪中的运动 。
A hibrid frequency domain and time domain method was introduced to predict the motions and mooring forces of a flexibly joint multi body floating system responding to waves. The three dimensional frequency method was used to obtain the hydrodynamic coefficients and the equations of motions were solved in time domain. The motions, nonlinear mooring forces and attaching forces between the adjacent bodies could thus be numerically computed at the same time. The motions and nonlinear anchor forces of rectangular frame type six body floating system were predicted. The comparison between the numerical prediction and the experimental results shows good agreement.
