Abstract

As essential equipment in rotating machinery, the fault diagnosis technology of rolling bearings has achieved great success. However, it still suffers from limitations in terms of generalization and noise resistance performance when operating under complex conditions. To accurately identify the fault types of rolling bearings under different loads and nosy environments, a novel intelligent fault diagnosis method is proposed. Firstly, the utilization of dilated convolution expands the network's receptive field, thereby effectively enhancing the scope of fault extraction. Then, by incorporating the Efficient Channel Attention (ECA) in different convolutional layers, the extracted features are adaptively recognized, highlighting important representation information and improving fault diagnosis performance. Finally, the proposed network is utilized for rolling bearing fault diagnosis under diverse operating and noise conditions, and its efficacy is evaluated on various datasets. The experimental results demonstrate that the proposed method exhibits good generalization performance and strong robustness, compared with other methods.

一种基于扩张卷积和注意力的滚动轴承多工况噪声环境故障诊断方法
滚动轴承作为旋转机械的重要设备,其故障诊断技术取得了巨大的成功。然而,当在复杂条件下操作时,它在泛化和抗噪声性能方面仍然受到限制。为了准确识别滚动轴承在不同载荷和恶劣环境下的故障类型,提出了一种新的智能故障诊断方法。首先,利用扩张卷积扩大了网络的感受野,从而有效地扩大了故障提取的范围。然后,通过在不同的卷积层中引入有效通道注意(ECA),自适应地识别提取的特征,突出重要的表示信息,提高故障诊断性能。最后,将所提出的网络用于不同运行和噪声条件下的滚动轴承故障诊断,并在各种数据集上评估其有效性。实验结果表明,与其他方法相比,该方法具有良好的泛化性能和较强的鲁棒性。
