本研究旨在探討新型單擺式電磁調諧質量阻尼器結合飛輪(EM-FW-TMD)之系統，在雙向不對稱結構系統中之動力行為及其減振效益。當結構的雙向頻率不同時，該系統首先控制頻率較高之方向，並通過設計單擺擺長及與頂層相連接的鋼纜產生回復力。此外，為克服控制頻率較低方向之擺長不足問題，引入安裝於旋轉馬達後軸的飛輪裝置以延長週期並降低離頻。本研究推導馬達傳動系統施加於TMD和主結構之作用力與反作用力，組成包括與相對速度相關的阻尼力和與相對加速度相關的慣性力。透過調整飛輪質量及外接電阻，構建具有可變質量和阻尼特性的新型減振系統，兼具減振與儲能功能。根據慣質與電磁式阻尼理論，比較滑動式和單擺式EM-FW-TMD系統的動力特性與減振效能，發展單一擺長單擺式TMD系統之動力分析，體現單擺長系統於計算過程及實務應用方面更加簡單易行。將單擺長單擺式EM-FW-TMD透過最佳化計算，於長週期向加裝飛輪，在裝設於雙向頻率不同之高樓結構，驗證其在風荷載與地震力作用下之減振效益。;This study aims to investigate the dynamic behavior and vibration reduction efficiency of a novel pendulum-type electromagnetic tuned mass damper combined with flywheels (EM-FW-TMD) system in bi-directional structural systems. When the frequencies of the structure differ in two directions, the system first controls the direction with the higher frequency by designing the pendulum length and generating restoring force through cables connected to the top floor. To address the issue of insufficient pendulum length for the lower frequency direction, a flywheel device installed on the rear axle of the rotating motor is introduced to extend the period and reduce detuning. This study derives the forces and reactions exerted by the motor drive system on the TMD and the main structure, which consist of damping forces related to relative velocity and inertial forces related to relative acceleration. By adjusting the flywheel size and external resistance, a novel vibration reduction system with variable mass and damping characteristics is constructed, featuring both vibration reduction and energy harvesting functions. Based on the theories of inerter and electromagnetic damping, the dynamic characteristics and vibration reduction performance of sliding-type and pendulum-type EM-FW-TMD systems are compared. It develops a dynamic analysis of pendulum-type TMD systems with single pendulum length, highlighting the simplicity and feasibility of the single pendulum length system in computational processes and practical applications. The pendulum-type EM-FW-TMD system with single pendulum length, through optimization calculations, is equipped with a flywheel for long-period tuning. Its effectiveness in reducing vibrations under wind loads and seismic forces is verified when installed in high-rise structures with different bidirectional frequencies.
