摘 要: Aiming at the problem that the traditional fault diagnosis method is difficult to effectively extract the fault features of the high-speed train wheelset bearing signal, this paper proposes a fault diagnosis method based on the two-dimensional image method. First, the one-dimensional vibration signal is converted into a Two-dimensional grayscale image, eliminating the influence of expert experience on the feature extraction process. Then an improved network model is proposed, which can automate the process of feature extraction and fault diagnosis. Finally, this paper simulates the complex driving environment of high-speed trains by adding noise with different SNRs to the vibration signal and analyzes the influence of noise on the diagnostic ability of the method. The results show that the method is effective.

针对传统故障诊断方法难以有效提取高速列车轮对轴承信号故障特征的问题,本文提出了一种基于二维图像的方法。首先,将一维振动信号转换为二维灰度图像,从而消除了专家经验对特征提取过程的影响。接着,提出一种改进的网络模型,可实现特征提取和故障诊断过程的自动化。最后,通过在振动信号中加入不同信噪比(SNR)的噪声,模拟高速列车复杂的运行环境,分析了噪声对方法诊断能力的影响。结果表明,该方法具有良好的有效性。
