| Abstract: | Based on the characteristics of Qukou Bridge in Kai county, the three-dimensional discrete freedom model of vehicles and the modal model of bridge are established individually.Through the interactional relationship between the wheels and the tracks, the dynamic model of the coupling vibration of vehicles and bridge are established.The research on coupling vibration of vehicles andbridge of Qukou Bridge in Kai county is made.It can provide reference for this study on this kind of problems. |
