Electromechanical De-icing of Rectangular Aluminum Plates with Forced Vibration Generated with an Amplified Piezoelectric Actuator

This paper describes the feasibility of a de-icing device based on forced vibrations induced in an ice-covered rectangular aluminum plate using an amplified piezoelectric actuator. The removal of the ice layer is caused by the creation of mechanical stresses induced by relatively fast time-varying mode shapes in the very low kHz-range large enough to overcome the adhesion forces at the material/ice interface.
