车-桥耦合系统MTMD振动控制参数研究
Research on MTMD Vibration Control Parameters in Vehicle-Bridge Coupled System
摘要
Abstract
In this paper,a continuous beam model of Vehicle-Bridge Coupled System ( VBCS) is built and the vibration 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 in simulating 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 analyses the torsion vibration effect of the high-speed railway bridge. And the results show that the torsion vibration has a great impact on the bridge under the high-speed train loads. Finally, the MTMD arrangement and parameter design have been improved.关键词
