Temperature Characteristics of Axle-Box Bearings Under Wheel Flat Excitation

Temperature Characteristics of Axle-Box Bearings Under Wheel Flat Excitation

The high-amplitude and high-frequency wheel–rail impacts excited by wheel flat result in severe contact friction in axle-box bearing (ABB), and the friction can cause a temperature rise or even structural damage of ABB. To this end, a thermal analysis model considering the vehicle operation environm...
