A Study on the Optimum Design of the Piezoelectric Actuator Using the Finite Element Method

유한요소법을 이용한 압전 액츄에이터의 최적설계에 대한 연구

In this paper, the multilayer actuator is investigated by using the finite element method. The material is taken to be piezoelectric. The capacitor and interdigital wlfloating type actuator are compared to the stress field distribution under the uniform electric field. As the length of the floating electrode in the interdigital wlfloating actuator changes, the stress field around the edge of electrode is studied.
