Analysis Of Vibration Performance On Space Frame Structure Station

Elevated stations are engineering background of this article which analyze thedisplacement response of the the station structure caused by the vehicle. The stationmain body has three layers of frame structure and its integrated structure by verticalbearing component connected with the platform layer.Vibration caused by the traininto and outbound station is passed to the upper structure and the lower structure. Theresult of this transfer may cause fatigue failure of the structure of the station andpassenger comfortment and so on. The research on the action of the vibrationdisplacement response caused by the train is necessary to ensure the operational safetyof the station structure and passenger comfortment. In this paper, a preliminary studyon the vibration displacement caused by the train station frame structure problem, themain work is as follows:(1) Simplify the study, considering the elevated station and track structure as awhole system of vibration response of the main body. Train is considered as a wholeof the vibration response of the applied body. Using ANSYS structural analysissoftware to establish elevated stations and track structure model,is focus to considerthe composition of the various parts of the system and connection. Modeling theextended modal analysis is to get the top10order of the elevated station and trackstructure system from the natural frequencies and the corresponding modes. Analysestructure system under dynamic action in different moments of the nodaldisplacements, structural deformation, and the process of structural node displacementcurves of the train vertical live load and horizontal direction during train to enter thestation to the train stop movement.(2) Analysing the influence of the rubber bearing stiffness change between theconnection framework beams with box continuous beam (track beam) and the largerubber pad stiffness change connecting reinforced concrete pad and track bed to thestructure of the main vibration characteristics and structural vibration response.(3) Through the above simulation analysis, which gets rubber bearing stiffness andlarge rubber bearing stiffness which is the most conducive to reduce the vibration...
