This paper describes an analytical approach of the coupled vibrations between railway vehicle wheels and a rail in the horizontal direction using an approximate model. The model is an analytical one with an infinite number of vehicles in which these vehicles are arranges with a certain periodicity on the top of an infinitely long and straight rail installed on two distributed springs. It is effective for the analysis of the actual system of railway vehicle wheels and rail. The authors treated the wheel as a rotating Mindlin circular plate and the rail as a Timoshenko beam of coupled bending and twisting, and analysed the coupled vibrations taking the creep forces acting on the points of contact between rotating wheels and rail into account. The numerical computational results of Shinkansen vehicles demonstrated the validity of the present model, and were compared under the various conditions.
