三体船耐波性预报

应用三维势流理论,计算了三体船在不同航速下垂荡、纵摇、横摇运动频率响应函数。预报了三体船在不规则波中各种海况下航行时的运动和加速度有义值,同时分析了三体船在西北太平洋海区一定海况下的运动特征和规律,最终根据舰船耐波性衡准要求,确定了三体船适合航行的海况与航速,为三体船耐波性方面得出了有价值的参考。

Prediction on Sea-keeping Performance of Trimaran

By using 3D Potential Flow Theory, the frequency response functions for heave, pitch and roll were computed for a trimaran under various speeds. The meaningful values of motion and acceleration of the ship in irregular waves under several sea states were predicted. The motion characteristics and rules of the trimaran voyaging in the Northwest Pacific ocean under certain sea conditions were analyzed. Finally, according to the requirement for sea-keeping performance, the suitable sea states and speed were determined in this paper. The results provide a valuable reference for the study of sea-keeping performance of trimaran.
