摘要:
建立了车-桥耦合系统的连续梁模型,对车-桥耦合系统的多重调谐质量阻尼器(MTMD)振动控制进行了研究.结合实例分析模态数对仿真计算的影响,给出了仿真计算应考虑的模态数取值,在保证计算精度的基础上大大减少了计算的工作量.考虑到目前新型高速铁路桥梁抗扭刚度较小,对高速铁路桥的扭转振动影响进行研究,结果表明扭转振动在高速列车作用下对桥梁有较大影响.最后,对MTMD的布置方式及参数设计进行了改进.
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.
