| 摘 要： | 摩擦TMD用摩擦阻尼替代传统的粘滞阻尼,可有效降低成本,促进其推广应用,但摩擦阻尼的非线性给摩擦TMD分析和设计造成了一定的困难。本文首先对常摩擦单自由度系统的自由振动和强迫振动特点在时域和频域内进行了分析,然后从理论和试验两方面分析了常摩擦TMD在简谐激励下对单自由度主结构响应的控制效果。结果表明,常摩擦TMD系统存在停顿现象,参数设置合理,TMD能启动的情况下,其简谐激励控制效果令人满意。

| Abstract: | It can reduce the cost of TMD and improve its application in real projects to replace conditional viscous damping with friction damping in TMD.However,friction element is non-linear,which make the analysis and design of friction TMD difficult.In this paper,free vibration and forced vibration of SDOF frictional system is analyzed in time and frequency domain.The control effectiveness of frictional TMD to SDOF structural response under harmonic excitation is studied theoretically and experimentally.The result... |
