Coupled Vibrations Between Railway Vehicle Wheels and a Rail : Coupled Vibration Characteristics in the Horizontal Direction Taking Creep Forces into Account

Abstract

The authors analyze the coupled vibrations between wheels and a rail in the horizontal direction, taking Kalker's linear creepage theorem into account. They calculate the steady-state responses of the Shinkansen wheels and a 60 kg rail at the points of contact and investigate the individual characteristics of a rotating wheel theoretically and experimentally. It is found that the rail is strongly influenced by the wheel characteristics in the coupled vibration while the wheels themselves retain their individual characteristics.
