摘要
在车桥耦合振动研究的基础上,对货车动力模型中的中央悬挂装置采用变摩擦阻尼,通过与某高墩连续梁桥实测结果的对比分析说明,理论计算结果是可信的;对高墩连续梁桥动力响应的进一步分析结果表明,低墩和高墩的墩顶振幅相对较小,而具有相对较小横向刚度的中等高度桥墩的墩顶振幅却较大,这种情况值得注意。
Based on the research of vehiclebridge coupling vibration, the variable friction damping is employed to the central suspension freight train in the vehicle dynamics model. The field test result on a railway continuous beam bridge shows the reliability of the theory result. Further analysis demonstrates that the amplitude of low and high pier is relatively small, while that of median pier with relatively small lateral stiffness is large, which is worth to notice.
