Dynamic Interaction Analysis of Tilting Train and Curved Track

Abstract

In this study, a new dynamic interaction analysis method for tilting trains and curved track is presented. Three dimensional lumped parameter vehicle elements are used to model tilting train, and the proposed analysis technique can simulate driving direction change of vehicle, the effect of track cant, wheel-rail contact angle, and tilting angle of tilting trains, etc. The proposed method passed several basic verification tests, and it is expected that the suggested method is applicable for practical problems.

A Study on the Characteristics for the Ground Vibration Due to the Travelling Tilting Train

“…Since the train convoy combines these different cars, applying a different elevation of the center of gravity for each train is difficult. Assuming that the conditions of the track are generally identical, a train with low center of gravity has a higher safety factor for the overturning outward the rails than a train with high center of gravity [2,3]. Figure 4 illustrates the equilibrium of the forces of the tilting train during the crossing of a curved section.…”
