Abstract: The main problem in railway field is high wear rate due to increasing of the capacity needed. It will cause the reliability and availability of facilities and infrastructure to decrease, even increasing the derailment accident and operational cost. This wear is due to the high contact load that occurs on the interface of contact between wheel and rail. The highest wear rate occurred commonly at the curve track. This research examined the effect of curving speed and mass of vehicle to the normal forces, contact area and contact pressure on the contact path between wheel and rail. The effect would be investigated when the vehicle passed on the curve track. By using universal mechanism software, the simulations are presented. It is found that the wheel on the leading wheelset of front left bogie of vehicle receive the highest load. On the tread contact, increasing vehicle mass had more influence than increasing curving speed. Meanwhile, on the flange increasing curving speed gives greater influence than increasing vehicle mass.

Keywords: railway vehicles; contact force; contact area; contact pressure; wheel rail contact; wear; curved track; curving speed; vehicle mass; simulation.
