Abstract

A novel design of ring type piezoelectric actuator with waves reflecting active elements (the fixation ele-ments) generating elliptical movement is proposed and analyzed in the paper. Numerical analysis by FEM with the aim to determine natural frequencies and modal shapes of the resonator was carried out and motion path of interaction contact point found. The best results of model analysis of cross ply and rota4tive movement were found. Results of numerical studies are discussed.
