적층 압전세라믹 액츄에이터의 2차원모델 해석에 관한 연구
2-D Model Analysis on the Multilayer Piezoelectric Ceramic Actuators
초록
Finite element analysis was investigated on the stress distribution at the 2-D model of piezoelectric ceramic actuators. The y direction maximum stress decreased with a(internal electrode gap) size until 0.4 mm and is not much difference with c(external electrode thickness) size. The stress distribution with internal layers is almost same, and the stress distribution of load condition is higher than that of no load condition. The y direction maximum stress increased exponentially with the number of layer and saturated at 260 layers. In the case of defective actuator, the stress distribution is smaller than that of normal actuator.
