Compound Actuator for Linear Piezoelectric Motor having High Thrust Force

Abstract

In order to excite an effective vibration in the piezoelectric linear actuator we proposed the compound piezoelectric linear actuator for high thrust force based on "shaking beam". The compound actuator consists of two shaking beams and is rigidly fastened. Acoustical connection between each converter is weakened by using four grooves and a hole of the compound actuator. Finite element method (FEM) was used for defining structural and electrical boundary conditions for piezoelectric actuator. FEM analysis showed that the compound actuator's trajectory is an elliptical motion.
