Abstract

Detecting wheelset defects early is crucial for maintaining railway safety. Monitoring the condition of wheelsets provides ongoing insights into the system's health, thereby averting the need for time-consuming and costly periodic inspections. This study focuses on identifying wheel-flat defects in railway wheelsets using vibration signals obtained from axle-box measurements. Experimental campaigns were conducted on a wheelset test bench with defects artificially created. These tests aimed to carry out a time domain analysis on the vibration signals and detect features that can highlight the presence and the severity of a wheelset wheel-flat. Subsequently, an experimental campaign through the employment of sensor nodes was carried out on a Mercitalia freight train (Car T3000) to validate the obtained results.
