Abstract

This study analyzes the effect of changes in the shell thickness of a class IV flextensional transducer with an elliptical cylindrical shell on its resonance characteristics. A mathematical model was proposed, and both theoretical calculations and experimental results confirmed that the resonant frequency increases with shell thickness. The proposed model demonstrated high accuracy, providing a valuable foundation for optimizing transducer design and evaluating new designs.

본 연구는 클래스 IV 플렉스텐셔널 트랜스듀서의 타원형 원통 쉘 두께 변화가 공진 특성에 미치는 영향을 분석하였다. 수학적 모델을 제안하고, 이론 계산과 실험을 통해 쉘 두께가 증가할수록 공진 주파수가 상승함을 확인하였다. 제안된 모델은 높은 정확성을 보여 트랜스듀서 설계의 최적화 및 새로운 디자인 검토에 유용한 기초 자료를 제공하며, 수중 음향 송신기 및 광대역 수신기와 같은 응용 분야에 활용 가능성을 제시한다.
