摘要：
To enhance the vibration control performance of stay cables, a new self-powered MR damper hybrid vibration mitigation system based on the rotary electromagnetic vibration energy harvesting technique was proposed. The system consists of a current-adjusted MR damper, an energy-harvesting motor (permanent magnet generator) as well as a linear-rotary motion conversion mechanism (ball screw) that converts the linear vertical vibration of the cable into the back and forth rotation motion of the generator rotor. The electromotive force harvested by the generator was directly used to provide power supply to the induction winding of the MR damper, making the MR damper dissipate vibration energy of the cable without any external power supply. The generator serves as both an energy-harvesting motor and an electromagnetic damper that can also dissipate vibration energy of the cable. Model cable test results shows that there are coupling and interference between the MR damper and the generator. When the MR damper and the generator are attached at the same side of the cable, the control performance of the cable is even worse than a single damper. However, when the MR damper and the generator are attached at the different side of the cable, the control performance of the cable will be dramatically enhanced due to synergistic interaction effects. In conclusion, the superior control performance of the self-powered MR damper hybrid vibration mitigation system for the cable can be achieved through properly matching the location and parameters of the MR damper and the generator. The developed self-powered MR damper hybrid vibration mitigation system can provide a new potential technology and method for cable vibration control. © 2019, Editorial Office of Journal of Vibration and Shock.
