Abstract:

A Tuned Two-Mass Damper (TTMD), which consists of two undamped tuned mass dampers connected by a dashpot, has been demonstrated to be more effective than a traditional TMD. To improve the effectiveness and robustness of TTMD, an innovative type of TTMD used for structural vibration control is developed in this work. This innovative version consists of a TTMD connected to the ground by one or two inerters (TTMDGI). In this study, the three inerter-based configurations of TTMD are proposed. After developing three analytical models of the system with one of the proposed TTMDGI configurations, the optimal parameters of each TTMDGI configuration for various values of inertance are determined. From that, the performance and robustness of each TTMDGI configuration are calculated and compared to the inerter-based tuned mass damper. Additionally, the effects of the weight and inertance of each TTMDGI configuration on the structural response are investigated. This research indicates that the inerter-based configurations of TTMD are much more effective and robust than the TTMD. Furthermore, the performance of each optimal TTMDGI configuration significantly exceeds that of the optimal inerter-based Tuned Mass Damper (TMDI) with the same mass and inertance ratio. The effectiveness improvement is from 30.2 to 36.3% in the dynamic magnification factor of the structural response compared to TMDI as the inertance ratio rises from 1 to 5%. This significantly reduces the device’s weight added to the structure if using a TTMDGI configuration instead of a TMDI.
