Abstract
This paper discusses the effect of the structure and packing conditions of centre displacement of the membrane in a circular piezoelectric actuator. A mathematical model was constructed using classical laminated plate theory (CLPT) to describe the transverse displacement of a circular actuator. In the applied loading simulation, the effect on static displacement from varying the thickness in each layer of the structure as well as the packaging boundary constraint methods was studied. Results show the radius and thickness of the thin film has little effect on the maximum displacement, however an increase in elastic modulus decreased the maximum transverse displacement.
