Abstract

Abstract

The SMA (Shape Memory Alloys) are applied as actuators and a series of experiments have been done for investigating their mechanical behaviors.An intelligent support system has been designed for active control of high-speed rotor vibration and tested to verify its effectiveness.The tests indicate that the application has a magnificent effect on the active vibration control.
