Abstract
A comprehensive system designed for the predictive maintenance of railcar wheel bearings, integrating multiple sensor modalities. The system includes thermography for temperature mapping, vibration analysis via a three-axis accelerometer, rotational velocity measurement using a rate gyro, and optical spectrometry for lubricant analysis. Each modality contributes to a holistic understanding of bearing health, enhancing maintenance strategies, safety, and operational efficiency in rail transportation.
