K. Goel Emeritus Professor, MIED, IIT Roorkee Dr. V. H. Saran Associate Professor, MIED, IIT Roorkee ABSTRACT This paper presents a methodology and a simulation tool to predict changes of wheel profile due to wear. The methodology is based on a load collective concept. In the load collective, the railway network is primary discretized based on curve radius distribution. The vehicle track simulations have been performed with MBS tool GENSYS and wheel rail contact mechanics modeling is done .For Optimization, criteria formulated using the requirement to railway track and wheelset are related to stability of wheelset, minimum wear of wheels, ratio of lateral to vertical force and critical speed.

INTRODUCTION New specifications are being imposed on railway wheel wear and reliability to increase the time between wheel reprofiling operations, improve safety and reduce total wheelset lifecycle costs. In parallel with these requirements, railway vehicle missions are changing due to the need to operate rolling stock on track with low radius curves as well as the high radius curves on high speed lines, increasing speeds and the decrease of track quality due to a reduction in maintenance. These are leading to an increase in the severity of the wheel/rail contact conditions which will increase the likelihood of wear occurring. Excessive wear can affect the dynamic behavior of the railway vehicle and reduce ride comfort; impact upon the potential
