Vibration control of a rotor by magnetic shape memory actuators-an experimental work

Deficiencies in practical applications for magnetic shape memory actuators motivated the authors to start experimental and theoretical research in the field of multifunctional materials. The authors present the concept of using magnetic shape memory actuators for controlling, altering and tuning the forced vibration of a rotor. The main goal of their experimental research is to show how the activation of magnetic shape memory actuators can influence the forced vibration responses of a rotor in terms of altering and tuning selected rotor natural frequencies and modes of vibrations. Experimental results show that magnetic shape memory actuators can be successfully applied for vibration reduction and vibration control in the case of rotor systems.
