Abstract: Based on vehicle dynamics theory, the inter-vehicle hinge angle swing amplitude of electronic guided rubber-tyred tram is used as an evaluation index, and the stability of train operating in straight line under different speed conditions is studied by simulation analysis. On this basis, a passive inter-vehicle damper is designed, its working area and installation method are clarified and then verified through simulation analysis. Results show that after installing the inter-vehicle damper, the swing amplitude of the hinge angle under high-speed straight-line operation condition is evidently reduced, and the train running stability is significantly improved.
