| 摘 要： | 为研究在航集装箱船的摇摆姿态尤其是横摇姿态,利用假定概率模型的方法对集装箱船关键位置处的摇摆姿态进行研究,并构建摇摆概率模型,讨论并确定该模型的相关参数,从而建立集装箱船摇摆姿态的概率模型。结果表明,集装箱船不同位置处的纵摇角、横摇角和垂向加速度的概率模型近似服从高斯分布,仅其相关参数不同。该方法从在航集装箱船摇摆姿态的角度为船舶航行安全研究提供一定的理论依据。

A probabilistic model for swaying attitude of a container ship on the sailing |
| |
| Abstract: | In order to research the swaying attitude of container ships, especially the rolling attitude, the method that a probabilistic model is assumed is used. The swaying attitude of key positions of container ships is studied and the swaying probabilistic model is constructed. The corresponding parameters of the probabilistic model are discussed and confirmed. Based on the above, the probabilistic model of swaying attitude is established. The results show that the probabilistic models of the longitudinal swaying angle, the transverse swaying angle, and the vertical acceleration of container ships in different positions are subject approximately to Gauss distribution, but the corresponding parameters are different. This method provides theoretical basis for the ship navigation safety study from the angle of swaying attitude of container ships on the sailing. |
