Abstract

Many researches focus on piezoelectric ice protection systems with the objectives to develop light and low consumption electromechanical systems for de-icing. These systems use vibrations, generated by the excitation of flexural, extensional or coupled resonance modes, to produce tensile stresses in the ice or shear stresses at the interface ice/support in order to remove ice. The objectives of this work are to analyse flexural and extensional resonance modes according to important design drivers for this type of systems: resonance frequency range, generation of tensile and shear stresses, electromechanical coupling factor, damping and fracture propagation. A final comparison gives pro and cons of each mode type for each design drivers for helping the designer of piezoelectric ice protection systems.
