The use of Tuned Mass Dampers (TMDs) is a well-established method to reduce vibration in a range of structural systems, from skyscrapers to bridges. These systems are typically designed as single-degree-of-freedom devices, each tuned to reduce a single natural frequency.
The study presents an optimization method for tuning a multi-TMD (MTMD) system to reduce structural vibrations in a wider band of frequencies and several natural modes. The damping is
achieved using a magnetic braking based on eddy current induction, demonstrating a way to use an MTMD array while enabling a passive, contactless, and maintenance-free damping mechanism.
