基于多元统计的筒型基础海洋平台拖航分析

以筒型基础海洋平台为研究对象，通过模型试验测定了不同拖航组合时的平台加速度、拖缆力、筒内气压力以及筒底水压力，并用因子分析和聚类分析对10个力学参数测试结果进行分析比较，用于筒型基础平台随浪、顶浪时最佳拖航方式的选取判别．因子分析结果表明，总方差的82％的贡献来自于前3个因子，所对应的平台x、y、z方向加速度、拖缆力、1#筒与3#筒气压力以及1#筒水压力为系缆平台拖航的特征力学参数．聚类分析结果表明，可以通过筒型基础平台拖航过程力学参数的测定来归属不同的拖航组合．

Towing Analysis of Bucket Foundation Ocean Platform Based on Multivariate Statistics

Taking bucket foundation ocean platform for example, the internal air pressure and bottom water pressure of bucket, the acceleration and hauling power of platform were measured in the various combinations of towing of bucket foundation platform by using model test. Factor analysis and cluster analysis were applied to the comparison of the mechanical characters of 10 elements which are used in the judgment of the optimal towing in the fair and head waves. The factor analysis result shows that 82% of the total variance is attributed to the former three factors, which means that the acceleration of x,y and z, the hauling power, the internal air pressure of buckets 1 and 3 and bottom water pressure of bucket 1 are the corresponding characteristic elements in the towing. The cluster analysis result shows that through measuring the mechanical parameters during the towing of bucket foundation platform, the towing classification can be attained.
