STUDY OF FRETTING WEAR IN THE WHEEL-AXLE CLAMPED JOINT MODEL OF RAIL VEHICLES
Journal Title: Tribologia - Year 2017, Vol 271, Issue 1
Abstract
Wheelsets are among the key components of a rail vehicle. Their task is to guide the vehicle on the track. Any damage or wear may lead to derailment and cause a crash that may cost lives of hundreds of people. Therefore, a significant problem in the designing of wheelsets is the aim of the reduction of the excessive wear of wheelsets during operation. Wear tests of wheelsets under real working conditions are hindered due to their dimensions, the cost of construction of an appropriate testing station, and technological difficulties associated with proper disassembly of the wheel from the axle, which would not lead to the impairment of the overall picture of wear. The article discusses the methodology of a study of the fretting wear of the wheel/axle interference fit model of a wheelset. Thanks to the application of the appropriate criteria of the similarity of the model to the real object, the wear pictures developed may be referred to the wheelset wheel-axle clamped joint.<br/><br/>
