The Effect of Bearing Simulation on Vibration Characteristics of a Steel Box Girder Footbridge Model

Abstract:

The measurement and finite element simulation was used to research the effect of bearing on vibration frequency of bridge. Sixteen models accelerometer was instrumented on the bridge and the vibration signals were acquired at a sampling frequency of 512 Hz. The finite element software is adopted to establish the model of the bridge. In this paper, beam element simulation and elastic connection simulation are two ways to calculate the vibrational frequencies. Through comparison, the characteristics of the two simulation methods can be known. By this study, the bridge bearing simulation model of the bridge has an obvious impact on the frequency of bridge model. At the same time, the simulation of bridge should be as close to the reality as possible to obtain more accurate data.
