Abstract:
In this paper,a continuous beam model of Vehicle-Bridge Coupled System ( VBCS) is built and thevibration control of VBCS is studied with Multiple Tuned Mass Dampers ( MTMD). In combination with the a-nalysis impact of modal number on simulating calculation, this paper gives the considered modal number insimulating calculation, and greatly reduces the calculation effort on the basis of ensuring the accuracy of calculation. Considering the weak torsion stiffness of the present new high-speed railway bridge, this paper analysesthe torsion vibration effect of the high-speed railway bridge. And the results show that the torsion vibration hasa great impact on the bridge under the high-speed train loads. Finally, the MTMD) arrangement and parameterdesign have been improved.
