摘　　要：针对海底光缆敷设过程中的稳态运动问题,采用试验设计法分析各参数对张力的影响程度,并通过近似模型法拟合。首先,建立海底光缆敷设过程中的稳态模型,确定影响张力大小的关键参数及取值范围;其次,进行皮尔逊相关系数分析,确定各参数影响比重;最后,拟合试验数据构建近似模型,通过NSGA-II进行寻优得到Pareto解集。结果表明:多项式响应面法具有良好的拟合程度,能够代替复杂数学模型实现对海底光缆敷设过程中张力大小的计算;定余量敷缆时张力随船速的增加而略有减小,敷设余量越大张力越小。Aiming at the problem of steady-state motion during the laying of submarine optical cables,the experimental de⁃sign method is used to analyze the influence degree of each parameter on the tension,and the approximate model method is used to fit.First,a steady-state model during the laying of submarine optical cables is established,and the parameters and value ranges that affect the tension are determined.Secondly,the Pearson correlation coefficient is analyzed and the proportion of each parameter is determined.Finally,the test data is fitted to establish the approximate models,and through NSGA-II to optimize the model to get the Pareto.The results show that the polynomial response surface method has a good degree of fitting,and can replace the complicat⁃ed mathematical model to calculate the tension of the submarine optical cable during the laying process,with fixed-tension deploy⁃ment,the tension decreases slightly with the increase of ship speed,the greater the laying allowance,the smaller the tension.
