Abstract:
Vibrations in a railway coach are an important aspect that decides passengers' comfort level. These vibrations may be evaluated using several methods. The basis is to determine the inputs at the wheel-rail interface, then process them in terms of acceleration and assess the vehicle vibrations based on recommended comfort guidelines, i.e., the Sperling method, ISO-2631, etc. In the present work, a railway vehicle coach model is formulated using four approaches, i.e. analytical method (assigning it 37 degrees of freedom), BG-Simulink technique, Finite Element (Ansys) method and field testing. The ride comfort is determined under ISO-2631 comfort specifications using the rigid body (analytical) and flexible body (Ansys) models and then compared. The eigenfrequencies of the carbody are determined using analytical and Finite Element (Ansys) Methods. The eigenfrequencies determined from these methods compare well, justifying the model developed.
