| 摘 要： | 为节约昂贵的海上试验费用，以6个自由度最关键的横摇运动为例说明了仿真计算过程。在由船模试验得到船舶响应幅值算子（RAO）的基础上，采用ITTC单参数标准波谱计算船舶的运动幅值谱，然后采用线性迭加法得到船舶振荡运动的时域序列。仿真信号序列的频谱与实船采集的横摇运动数据的频谱具有相似性，对频率区间细分可以提高仿真结果的精度。

| Abstract: | The paper presented a method to generate both the translation and rotational motion of a ship subjected to wave motion. It is based on ship's Response Amplitude Operator (RAO), which can be generated from the scale model experiment. Applying ITTC sea wave spectrum, the ship's response amplitude spectrum can be formed. A time domain version of the response model is built by the linear superposition method. The Power Spectral Density (PSD) of the simulation results is similar in comparison with the data collected from a real ship. The paper illustrated the method with ship roll motion. |
