Abstract

The vibration and noise problem of large-span steel bridge in urban rail transit have received increasing attention in recent years. As a common vibration control measure, the vibration-reducing track has been widely used on concrete bridges. However, systematic research on the vibration and noise reduction characteristics of large-span steel bridge by using vibration-reduction track remains insufficient. At the present paper, the vibration and noise reduction mechanism and characteristics of three typical vibration-reducing tracks, which are applied on large-span steel bridge, are studied. Firstly, based on the vehicle, track, and bridge coupling theory, a theoretical analysis model in the frequency domain was established. The dynamic receptance, wheel-rail force, force transmissibility ratio, and force transmitted to the bridge can be obtained, which are used to analyze the vibration-reduction mechanism of each vibration-reducing track. Then, the vibration and noise prediction model of a large-span steel-truss cable-stayed bridge is established by plate-beam combined finite element method and statistical energy method, and verified though the measured results. Finally, the vibration and noise reduction characteristics and effects of large-span steel bridge under the three vibration-reducing tracks are analyzed.
