Abstract

Tram transportation is an integral element in many densely populated countries in the world. In Australia, the flange tip lift crossing (FTLC) is utilized as a replacement for the traditional crossings used in heavy hauls. FTLC eliminates high impact force by allowing the flange of the wheel to travel on a filled groove ramp of the tram rails. However, the ramp experiences high amount of wear due to an increase in contact pressure. To understand the wear behaviour of the ramp, a wheelset-crossing model was used in an implicit dynamic simulation. With local sliding distance and local contact pressure from the simulation, wear was evaluated with a local contact-based wear model. Wear in the ramp was observed to be significantly higher than the wear in the rail head.
