VEHICLE-BRIDGE COUPLING VIBRATION ANALYSIS ON SLIDING TURNOUT GIRDER OF STRADDLE-TYPE MONORAIL TRANSPORTATION

The sliding turnout shows better performance in the costs, repairing and safety. In order to Study the coupling of sliding turnout girder and vehicle, coupling vibration model of monorail vehicle-sliding turnout girder was suggested in the paper. In this model, the vibrations of vehicle, bogie and sliding turnout girder were synthetically considered. The vibration differential equations of the system were solved by direct integration method, and the coupling vibration responses of sliding turnout girder and vehicle were calculated. According to the analysis of calculating results, the rules that the Coupling of sliding turnout girder and vehicle is influenced by vehicle velocity were discussed.
