An Analysis of the Lateral Hunting Motion of a Two-Axle Railway Wagon by Digital Simulation : 1st Report, The Outline of the Mathematical Model

Abstract

To clarify the dynamics of the derailment of a 2-axle railway wagon caused by the lateral hunting motion, a mathematical model of the 2-axle wagon which is applicable even to the phenomenon similar to the derailment, is formulated. With this simulation model the dynamics of a 2-axle wagon on the track with irregularities is investigated making use of a digital computer. Results of the simulation are compared with the experimental results, and the adequateness of the model is confirmed.
