Frequency response of articulated railway vehicles (A method for dynamic analysis of intermediate vehicles in a long train)

Abstract

One of the most important characteristics of a railway system is that many coupled vehicles run in a long train. It forms mass transportation and extends many other advantages. However, most papers have treated dynamic analysis of railway vehicles as a single vehicle. This paper reports a new method using ""an equivalent one car model"", by which we can analyse the response of an intermediate car in a long train to track irregularities ; and also using this method, show the results of the essential difference in vertical frequency response between articulated vehicles and conventional two-bogie vehicles.
