Abstract
As a mass amplifier, inerter can provide two orders of inertia force of its own physical mass. In this paper, a novel control device, the Double Tuned Mass Dampers Inerters (DTMDI), is proposed to attenuate undesirable oscillations of structures under the ground acceleration. By establishing the motion equation of the system, we can deduce the mean square of displacement response of the primary structure. To verify the superiority of the new system, the numerical analysis of DTMD and DTMDI are conducted on MATLAB software platform. The optimal DTMDI is evaluated and compared with the DTMD by normalized mean square and the dynamic magnification factor (DMF). Results demonstrate that the proposed DTMDI not only performs better than DTMD in attenuating structural vibration but can also endow with the superior stroke performance of the mass block.
