基于有限元与改进SVM的飞行器结构无损检测模型设计
Design of aircraft structure nondestructive testing model based on finite element and improved SVM
摘要
Abstract
In allusion to the problems of low accuracy and easy to cause secondary damage in the traditional nondestructive testing of aircraft structure,a aircraft structure nondestructive testing model based on improved support vector machine(SVM)is proposed based on finite element simulation data.In the model,the principal component analysis(PCA)is used to analyze the main characteristics of the data,so as to solve the high dimension of finite element simulation data.The traditional SVM is improved by means of the idea of binary tree to make it have the ability of multi-feature classification and classification of multi-data features,and the convergence accuracy of the model is improved.The particle swarm optimization(PSO)is also introduced to optimize the penalty factor and kernel function parameters of the multi-classification vector machine.The experimental testing results show that the proposed model can realize the performance optimization of classifier parameters,with an average classification accuracy improvement of about 1.4%compared with the comparative algorithm.关键词
