This paper proposes a novel retrofittable approach for dual-functional energy-harvesting and robust vibration control by integrating the tuned mass damper (TMD) and electromagnetic shunted resonant damping. The viscous dissipative element between the TMD and primary system is replaced by an electromagnetic transducer shunted with a resonant RLC circuit. An efficient gradient based numeric method is presented for the parameter optimization in the control framework for vibration suppression and energy harvesting. A case study is performed based on the Taipei 101 TMD. It is found that by tuning the TMD resonance and circuit resonance close to that of the primary structure, the electromagnetic resonant-shunt TMD achieves the enhanced effectiveness and robustness of double-mass series TMDs, without suffering from the significantly amplified motion stroke. It is also observed that the parameters and performances optimized for vibration suppression are close to those optimized for energy harvesting, and the performance is not sensitive to the resistance of the charging circuit or electrical load.
本文提出了一种新颖的可改造方法，通过集成调谐质量阻尼器（TMD）和电磁并联谐振阻尼实现双功能能量收集与强大的振动控制。TMD与主系统之间的粘性耗散元件被一个与谐振RLC电路并联的电磁换能器所取代。提出了一种基于梯度的高效数值方法，用于在振动抑制和能量收集控制框架中进行参数优化。基于台北101大楼的TMD进行了案例研究。结果发现，通过将TMD共振和电路共振调谐至接近主结构的共振，电磁共振并联TMD实现了双质量串联TMD增强的有效性和鲁棒性，且不会出现显著放大的运动行程。还观察到，为振动抑制优化的参数和性能与为能量收集优化的参数和性能相近，并且该性能对充电电路或电负载的电阻不敏感。
