许多工作已经在振动吸收器上进行，例如调谐质量阻尼器（TMD），其中从结构中提取显著的能量。传统上，这种能量通过器件作为热量耗散。在本文中，这种能量的电力回收和再利用结构控制或健康监测的概念进行了研究。TMD的能量耗散阻尼器被电磁装置取代，以便将机械振动转化为电能。这使得在产生有用电能的同时控制阻尼力成为可能。给出了自适应和半主动调谐质量阻尼器/收获器的分析和实验结果。所获得的结果表明，可能会收获足够的能量，设备调整自己，以优化振动抑制。版权所有© 2014约翰威利父子有限公司.
Much work has been conducted on vibration absorbers, such as tuned mass dampers (TMD), where significant energy is extracted from a structure. Traditionally, this energy is dissipated through the devices as heat. In this paper, the concept of recovering some of this energy electrically and reuse it for structural control or health monitoring is investigated. The energy‐dissipating damper of a TMD is replaced with an electromagnetic device in order to transform mechanical vibration into electrical energy. That gives the possibility of controlled damping force whilst generating useful electrical energy. Both analytical and experimental results from an adaptive and a semi‐active tuned mass damper/harvester are presented. The obtained results suggest that sufficient energy might be harvested for the device to tune itself to optimise vibration suppression. Copyright © 2014 John Wiley & Sons, Ltd.
