Abstract

This paper is concerned with the development, and performance test of LIPCA (Lightweight Piezo-composite Curved Actuator) that is lighter than other conventional piezo-composite type actuators. LIPCA is composed of top fiber composite layers with a high modulus and low CTE (Coefficient of Thermal Expansion), a middle PZT cermaic wafer, and base layers with a high modulus and high CTE. The performance of each actuator was evaluated using an actuator test system consisting of an actuator supporting jig, a high voltage actuating power supplier, and a non-contact laser measuring system. The simply supported condition actuator was excited by the power supplier with 1.0Hz cycle and up to $100\sim400V_{pp}$. The displacement at the center point of actuator was measured with non-contact laser displacement measuring system, It has been shown that the LIPCA-C2 can 34% decrease in mass and 13% increase in displacement compared to THUNDER.

본 논문은 곡면형 압전 복합재료 작동기 LIPCA의 개발 및 성능 실험에 관한 것이다. LIPCA는 압전 세라믹을 중심으로 상층부는 탄성계수가 크면서 열팽창계수가 낮은 섬유강화 복합재료층이 위치하며, 하층부는 탄성계수가 작으면서 열팽창계수가 큰 섬유강화 복합재료층이 위치한다. 작동기의 성능 검증을 위해 작동지그 및 전압 공급 장치 그리고 비접촉 레이저 센서로 이루어진 실험 시스템을 구성하였다. 성능 실험은 양단 단순지지상태에서 압전 재료의 전극에 $100\sim400V_{pp}$의 교류 전압을 1Hz로 가하였을 경우 작동기 중앙부에서 발생하는 수직방향의 변위를 측정하는 것으로 수행하였다. LIPCA와 THUNDER의 성능 검증 결과 LIPCA-C2는 THUNDER에 비해 34% 경량화 되었으며, 작동변위는 13% 향상되었다.
