摘要
应用支持向量机对KVLCC2约束船模斜拖试验结果进行了分析,通过对有限样本数据的拟合,辨识了描述船体横向力和转首力矩的数学模型中的水动力导数。应用所获得的回归模型,对不同工况下的测试样本进行预报,预报结果和试验结果的比较验证了方法的有效性,可以用于指导约束船模试验。
Support Vector Machines is used to analyze the results of captive model oblique towing test of KVLCC2.By regressive analysis of the limited samples,hydrodynamic derivatives in the mathematical models of hull force and moment are identified.By using the regressive models,hull forces and moments under different test conditions are predicted.The validity of the proposed method is verified by comparing the prediction results with the test results.The proposed method can be helpful in conducting captive model tests.
