COUPLED VEHICLE/TRACK DYNAMICS

Dynamic coupling occurs between a railway vehicle and the track due to the reaction forces acting between the wheels and the track, and the elasticity of the track and the foundation. It has become apparent that track elasticity can influence the dynamic behaviour of the railway vehicle, yet in most of the research work in the area of railway vehicle dynamics reported so far, the track is regarded simply as a rigid structure, providing the reactions to the loads of passing vehicles. In this paper the models used for the analyses of the vehicle dynamics (on rigid track) and for the coupled vehicle/track dynamics are described. The equations of motion are derived, and the results obtained for the coupled vehicle/track model are presented and compared with those obtained for the case of an infinitely rigid track. Particular empahsis is on the lateral stability and the response to vertical track irregularities.
