The Research on Dynamic Performance of Straight Going Fast Assembling Car Overpass

Abstract:

In order to solve the traffic jams and congestion of urban transportation in most cities, the steel trussed cable-stayed car overpass model is analyzed through the finite element modal analysis by ANSYS software based on the design concept of straight going fast assembling car overpass. After understanding the laws of free vibration characteristics of the structure, the variation of maximum deflections and stresses of the structure which is under the loads moved at different speeds are studied by moving load transient analysis of full method. The result further testifies that the structure is reliable and safe. Also, the range of the optimum speed is summarized to provide reference for the design of speed-limiting facilities of the car overpass.
