Aiming at the fault diagnosis issue of rotating machinery, a novel method based on the deep learning theory is presented in this paper. By combining one-dimensional convolutional neural networks (1D-CNN) with self-normalizing neural networks (SNN), the proposed method can achieve high fault identification accuracy in a simple and compact architecture configuration. By taking advantage of the self-normalizing properties of the activation function SeLU, the stability and convergence of the fault diagnosis model are maintained. By introducing α -dropout mechanism twice to regularize the training process, the overfitting problem is resolved and the generalization capability of the model is further improved. The experimental results on the benchmark dataset show that the proposed method possesses high fault identification accuracy and excellent cross-load fault diagnosis capability.
针对旋转机械的故障诊断问题,本文提出了一种基于深度学习理论的新方法。该方法通过将一维卷积神经网络(1D-CNN)与自归一化神经网络(SNN)相结合,在简单紧凑的架构配置下实现了高故障识别准确率。通过利用激活函数 SeLU 的自归一化特性,保持了故障诊断模型的稳定性和收敛性。通过引入两次 α -dropout 机制对训练过程进行正则化,解决了过拟合问题,进一步提高了模型的泛化能力。在基准数据集上的实验结果表明,所提出的方法具有较高的故障识别准确率和出色的交叉负载故障诊断能力。
