The Dynamic Simulation Of Vehicle–Bridge Interactions Using Bond Graph Technique

Abstract

SUMMARY This paper describes the bond graph modelling technique for vehicle–bridge coupling system. The vehicle system is considered as a multiple rigid–body model and the bridge with single-span is considered as a simply supported Bernoulli–Euler beam. The track is simplified as a lumped parameter system and the effective rail and sleeper masses are included in the vehicle–bridge coupling model. Finally, the dynamic responses of a freight vehicle–bridge system and wheel / rail impact forces have been investigated.
