With Chongqing Dongshuimen Yangtze River Bridge as the object of research, this paper establishes a vehicle-bridge coupling dynamic system and studies its response to vibration and comfort degree of driving. The paper adopts multi-rigid-body structures to simulate vehicles and spatial link elements to simulate bridges, calculates dynamic responses of bridge coupling light-rail vehicles and automotives, respectively, and evaluates the comfort degree of driving of light -rail vehicles and automotives on bridges. The results show that the comfort degree of driving of both light-rail vehicles and automotives satisfies the requirements.
