本文对著名的 5415 护卫舰船体在完整和受损情况下的运动预测进行了广泛的研究。实验活动针对两个 1/100 和 1/51 比例的地球模拟模型，在首海、横梁和四等海中以零速度进行。 1/51 模型的所有实验结果均以一阶和二阶 RAO 形式呈现，评论了二阶响应发生的物理原因。结果显示了船体受损时运动响应的变化，突出了模型尺度效应，并展示了模型自由漂移试验与模型平均位置受限制试验之间的比较。对于自由漂移试验中的受损船舶，损伤开口方向是不同的，并且评论了其对 RAO 和自由漂移速度的影响。
This paper presents an extensive study on the experimental prediction of motions for the well-known 5415 frigate hull in intact and damaged conditions. The experimental campaign is conducted for two geosim models, 1/100 and 1/51 scale, at zero speed in head, beam and quartering seas. All experimental results for 1/51 model are presented as 1st and 2nd order RAO, commenting on physical reasons for second order response occurrences. The results show the changes in motion responses when a ship hull is in damaged condition, they highlight the model scale effects and demonstrate the comparisons between the tests in which the model may freely drift and those in which the mean position of the model is restrained. For damaged ship in free drift tests the damage opening orientation is varied and its effect on RAO and free drift velocity is commented.
