摘要

This study investigates a novel electromagnetic tuned mass damper with flywheels (EM-FW-TMD) system for reducing building structure vibration. The EM-FW-TMD system comprises a tuned mass damper (TMD) system with an electromagnetic (EM) damper and flywheels (FW). The EM damping coefficient and inertance of the EM-FW-TMD are adjustable. A prototype EM-FW-TMD device is fabricated and tested to validate its adjustability. Sliding- and pendulum-type EM-FW-TMD systems with various inerter configurations are investigated. The equations of motion for single- and multiple-degree-of-freedom structures in which the two EM-FW-TMD systems are installed are derived. A parameter optimization method that considers inertance is proposed for the EM-FW-TMD systems. The control performance of the two EM-FW-TMD systems is extensively compared. Furthermore, for frequency detuning, a parameter redesign method is proposed for adjusting the inertance and EM damping coefficient of both types of EM-FW-TMD systems; the results indicate that the detuning effect can be significantly mitigated by this retuning method.
