| 中文摘要: |
| 为研究风、浪、流、涌以及船舶装载状态等因素对码头系泊船舶缆绳受力影响的相对大小及线性关联程度，基于水动力计算软件AQWA计算获得400组不同影响因素组合下的缆绳受力数据，运用机器学习中常用的无监督学习算法k-means++算法以及灰色关联分析方法，分析缆绳受力与影响因素的内在联系．根据分析结果，获得了各因素对不同位置缆绳受力影响的相对大小及线性关联程度．该方法可用于优化系泊缆绳的布置方案． |
| 英文摘要: |
| In order to study the relative magnitude and linear correlation degree of the influence of wind, wave, current, swell and ship loading state on the cable force of the mooring ship in the port, based on the 400 groups of cable force data calculated by hydrodynamic calculation software AQWA under different combinations of influencing factors, the internal relationship between the cable force and the influencing factors is analyzed by using the k-means++algorithm, an unsupervised learning algorithm commonly used in machine learning, and the grey relational analysis method. According to the analysis results, the relative magnitude and linear correlation degree of each factor on the cable force at each position are obtained. The method can be used to optimize the mooring cable layout plan. |
