Piezoelectric bimorphs for laser shutter systems: optimization of dynamic characteristics

Abstract

The paper considers optimal design problems in the context of piezoelectric bimorph actuator dynamics. The width profile of a piezoelectric bimorph actuator is optimized. The study utilized the finite element method to optimize the width profile of the cantilever beam in order to determine the resonance frequencies of the bimorph. The optimal form of actuator was found considering to theoretical calculations and experiment results. The calcu-lation method and experimental measurements of dis-placements of piezoelectric bimorphs are presented.
