Abstract
The Kirchoff-Love plate theory and electroelasticity theory are combined to formulate the computer aided design model for the trimorph ring actuators. An isotropic elastic ring is laminated between two identical piezoelectric rings to form the trimorph actuator. The inner surface of the actuator is fixed, and the outer surface is free or transversely load. The analytical solutions for the transverse displacement and the force distribution are derived. Numerical simulations for the transverse displacement under free and loaded boundary conditions are conducted. The maximum transverse displacements as functions of the geometry variables such as the thickness ratio and radius ratio are calculated and presented.
