Abstract

In "Rail Vehicles", the "Bogie" is the main part that connects the car body to the rail. It transmits loads from the car body (locomotive, passenger or freight cars) to the rail and allows the motion of rail vehicles. Wheel profile has a significant effect on the running behavior of bogies. In this paper, the aim is to explain the effects of wheel profiles on the wear of wheel and rail. Three wheel profiles: "S 1002", "SZD" and" a worn profile in the taper head of the wheel" (with rail profile UIC60 (1/40 inclination)) are considered. After profile analyzing, the behavior of an MD36 bogie is considered. Hunting in bogies is described and the effect of these profiles on the stability of the bogie is defined. A curved rail with a 200m radius and random irregularities is considered and the effect of these three profiles on the running behavior of the bogie, such as: derailment, ride comfort, forces in suspension elements and wheel wear are obtained. Finally, the results for these three profiles are compared and it is shown that the wheel profile has a very high influence on wheel wear. Also, it is shown that the wear in the taper head of the wheel profile is very important and measuring the flange thickness is not enough for checking the wheel profiles.
