摘要:
本文解决了通过分析常规运营中录制的声学信号来检测轨道车辆轴承故障的挑战。为此,我们引入梅尔频率倒谱系数(MFCCs)作为特征,构成简单多层感知机分类器的输入。所提方法用真实世界数据评估,该数据通过针对最先进通勤轨道车辆的测量活动获得。实验表明,使用所选MFCC特征,即使训练中未包含的轴承损坏也能可靠检测。
英文摘要:
In this paper, we address the challenging problem of detecting bearing faults in railway vehicles by analyzing acoustic signals recorded during regular operation. For this, we introduce Mel Frequency Cepstral Coefficients (MFCCs) as features, which form the input to a simple Multi-Layer Perceptron classifier. The proposed method is evaluated with real-world data that was obtained for state-of-the-art commuter railway vehicles in a measurement campaign. The experiments show that with the chosen MFCC features bearing faults can be reliably detected even for bearing damages that were not included in training.
