Optimization for High-speed Wheel Profiles

Abstract:

A target-oriented method for the design of railway wheel profiles is presented.The target chosen is the rolling radii difference function which plays an important role in the dynamics of railway vehicles especially for high speed performances.A computer program based on this method is also developed and validated by examples in which wheel profiles LMa,S1002G and XP55 are investigated.An optimization process for selecting a suitable profile for high-speed vehicle is put forward.
