中文摘要针对汽车变速箱原始故障特征向量维数过高导致的检测效率低、准确率低的问题,提出一种基于阶次分析理论的特征提取方法和基于遗传算法—反向传播神经网络的特征选择与分类方法。首先运用阶次分析理论提取变速器的阶次域特征,与时域特征共同组成特征向量集;然后将类内类间距离比与惩罚系数之和作为目标函数值,利用遗传搜索策略对特征向量集进行特征选择,得到特征子集;最后用反向传播神经网络算法进行故障分类,得到检测结果,并通过实验验证了所提出方法的有效性。
英文摘要During the process of new transmission products quality inspecting,the original fault feature vector dimension was too high to cause the detection in a low efficiency rate and low accuracy rate.To solve this problem,a feature extraction method based on order analysis theory together with a feature selection and classification method based on Genetic Algorithm-Back Propagation(GA-BP)algorithm were presented.The transmission’s order domain feature was extracted by using the order analysis theory,and it was composed with the domain’s feature to form a feature vector set.The sum of the penalty factor and the distance ratio of inner-class and between-class was taken as the objective function value,the features of feature vector set were selected by Genetic Algorithm(GA),and the feature subset was obtained.Back-propagation neural network algorithmare was applied to classify the fault.The effectiveness of proposed algorithm was validated by experiments.
