| 摘 要： | 将预报船舶运动和波浪载荷的切片理论加以扩展，应用于有限深水中船舶迎浪航行时大幅纵向运动和波浪载荷的时域求解。预报结果体现出考虑了湿表面及化后引起的船舶运动和受力的非线性性质。本计算方法简便、实用，适用于船舶纵向大幅运动预报。

| Abstract: | Based upon the strip theory a convenient and pragmatic numerical scheme is proposedto calculate the wave induced large amplitude vertical motions and sea loads in time domainfor a ship moving in head waves, the prediction results demonstrate the nonlinear characteristic of ship motions and sea loads caused by the alteration of the wetted hull surface.The computation method is suitable for the case of finite water depth, and useful for evaluation of seakeeping performance in the ship design stage. |
