Abstract
In the fault detection of mechanical rotating parts such as gears and bearings using data-driven methods, the working condition data sets detected by sensors have the characteristic of imbalanced proportion of positive and negative samples, which makes it difficult for machine learning classification methods to accurately identify fault samples. This paper proposes a method combining Synthetic Minority Over-Sampling Technique (SMOTE) with Generative Adversarial Networks (SMOTIFIED-GAN) to pre-process the training data. The input random noise of generator in GAN is replaced by the synthetic sample of SMOTE, which makes the samples more consistent with the real distribution, to solve the imbalanced class problem, thus improve the fault diagnosis ability of the classification model. This method is applied to experimental gearbox fault datasets. The classification ability and robustness of the detection model in different imbalance rates are analysed, and the results show that SMOTIFIED-GAN improved the detection rate. Compared with the traditional methods, the F1 score of fault detection results is improved, and the feasibility of the proposed method.
