Abstract

Abstract

The modelling of vestibule diaphragm was discussed. Based on the dynamic model of a single passenger car, a train dynamic model with three passenger cars was derived. By solving the differential equation groups to describe the train system, a series of simulation results about hunting motion stability, dynamic negotiation and ride comfort were worked out. The results show that the hunting motion of the train is due to the last bogie of the last car; the negotiation ability gets worse with the increasing of curving speed and the decreasing of curve radius; the ride comfort of the middle car is better than that of the head car and the tail car; the ride comfort of the train with tightlock vestibule diaphragm is the worst. It is suggested that the cushioning device should be added to the train with tightlock vestibule diaphragms.
