摘　　要：基于支持向量机,采用RBF核函数,以某集装箱船上层建筑舱室振动为训练样本,建立了集装箱船上层建筑舱室振动的非线性回归模型,对该船上层建筑部分舱室振动进行预测。通过对上层建筑振动特征的分析,构造转换系数,提高了模型的通用性,并应用此模型对另一艘集装箱船上层建筑舱室振动进行预测。预测结果表明:应用SVM非线性回归模型对大型集装箱船上层建筑舱室振动进行预测是可行的,预测效果较为理想。The nonlinear regression model of the vibration of the superstructure cabins of large container ship is established based on Support Vector Machine, using RBF kernel function and taking the vibration of one container shiprs superstructure cabins as the training sample, and the vibration of some cabins of the ship＇s superstructure is predcted in this paper. Moreover, in order to improve the generalization of the model the switching coefficient is constituted by means of analyzing the vibration characteristic of superstructure. The model is applied to predict the vibration of another container ship＇s superstructure cabins. The result shows that it is feasible to predict the vibration of the superstructure cabins of large container ship by using the SVM nonlinear regression model, and the effect is good.
