基于改进的LS-SVM的潜水器拘束模试验分析方法

Analysis Method of Captive Model Test of Underwater Vehicle Based on Improved LS-SVM

以最小二乘支持向量机为基础,将增量法和滑动窗口法相结合,建立适用于分析处理大样本数据的方法。采用该方法对某潜水器拘束模斜航试验和纯横荡试验进行了分析,获取了可以反映潜水器横向力、转首力矩的数学模型中的水动力系数,并利用构建的数学模型,预报多种工况下的潜水器所受到的水动力。通过比较预报结果和试验结果,证明了该方法的有效性。

Based on the least square support vector machine,incremental method with sliding window method to establish a method suitable for analyzing and processing large sample data are combined.This method is used to analyze the deflection test and the pure transverse test of a submersible restraint mode,and the hydrodynamic coefficient of the model which can reflect the lateral force and turning moment of the submersible is obtained.Using the constructed mathematical model,the hydrodynamic force under various working conditions is predicted.This method is proved to be effective by comparing the forecast and experimental results.
