摘要

针对轴承故障样本稀缺，传统深度神经网络模型在小样本情况下容易出现过拟合现象，泛化性能不好的问题，本文提出一种基于CNN-BiGRU孪生网络的轴承故障诊断方法。孪生网络采用两个结构相同、权值共享的卷积神经网络和双向门控循环单元组成，构造相同类别和不同类别的轴承样本对输入孪生网络，通过计算轴承样本对之间的L1距离进行相似性度量，实现轴承故障诊断。与传统深度神经网络相比，孪生网络采用样本对训练的方法，在相同样本数量情况下，增加对网络模型的有效训练次数，从而提高轴承故障诊断性能。设计卷积神经网络和双向门控循环单元共同组成孪生网络结构，可以从振动信号中同时提取空间特征与时序特征，提高特征提取的准确性。利用实测轴承故障信号进行故障诊断实验，并与其他深度神经网络模型进行对比，实验结果表明，CNN-BiGRU孪生网络方法在少量训练样本情况下，取得了较优的故障诊断性能，有一定的工程应用价值。

Abstract

Aiming at the problems that the fault sample was scare and over-fitting in traditional deep neural network model in small samples and poor generalization performance, a fault diagnosis method based on CNN-BiGRU Siamese network was proposed. Siamese networks were composed of two convolution neural networks and bidirectional gated recurrent unit that had the same structure and shared weights, the bearing sample pairs of the same category and different categories were constructed to input the Siamese network and the similarity was compared based on the L1 distance to achieve fault classification. Compared with the traditional deep neural network, the Siamese network adopted the method of sample pair training, which increased the effective training times of the network model under the same number of samples, so as to improve the performance of bearing fault diagnosis. The convolution neural network and bidirectional gated recurrent unit were used to construct the Siamese network, which can extract spatial and temporal features from vibration signals at the same time, improved the accuracy of feature extraction. The fault diagnosis experiment was carried out by using the measured bearing fault signal, and compared with other deep neural network models. The experimental results show that the CNN-BiGRU Siamese network method still had superior diagnostic performance in the case of small samples and had a certain engineering application value.
