Wheel Wear Modelling Including Disc Braking and Contact Environment: Simulation of 18 Months of Commuter Service in Stockholm

Wheel Wear Modelling Including Disc Braking and Contact Environment : Simulation of 18 Months of Commuter Service in Stockholm

QC 20100531
This paper addresses some aspects of modelling and validation of wheel wear simulation. In previous work at KTH the influences of braking and lubrication have been accounted for through empirically estimated average scaling factors. The current research shows how to include those effects in the set of simulations instead. Disc braking has been included in the simulation set and a wear map for moist contact conditions based on recent tribometer tests has been drafted and tested. Good agreement with measurements from theStockholmcommuter service is achieved. It is concluded that the model improvements accounted for are sufficient for adequate simulation of tread wear but that further development of the flange / gauge corner contact modelling is needed.
