Abstract
An elastic support/dry friction damper using piezoelectric ceramic was designed and its effectiveness of reducing rotor vibration was experimentally verified. Firstly, the basic operation mode of elastic support/dry friction damper was introduced. Then based on the previous structure using an electromagnet, an elastic support/dry friction damper using piezoelectric ceramic which was simpler and lighter was designed, and its effectiveness of reducing rotor vibration was experimentally verified. The experimental results show that the elastic support/dry friction damper using piezoelectric ceramic can significantly reduce vibration in a rotor system; the maximum reduction of vibration amplitude is about 66% at the critical speed. Compared with the previous design, the structure is much simpler, the weight is reduced by half and the power consumption is just 5 W.
