Abstract
An active elastic support/dry friction damper is designed and experimental investigations on its effectiveness of reducing rotor vibration are carried out while using switch control and P control schemes. It is proven that the damper is very effective to reduce rotor vibration, and there is no changed of the critical speed of rotor system comparing to the passive damper. Experimental shows that the damper is easy to be controlled, quick response from a stable state to another stable state without instability, and only little electric power is needed in the control procedure. Such an active elastic support/dry friction damper is promising in practical application.
