Abstract

In this work, we proposed various structural methods to reduce the crosstalk between elements in a planar array of underwater acoustic transducers and investigated the efficacy of each method through finite element analysis. It is shown that the effects of crosstalk reduction increase as the depth of the kerf among elements and the width of the kerf increase, and the elastic stiffness of the kerf filler decreases. Results of this study are expected to be useful in designing the structure of underwater acoustic planar array transducers to maximize their performance.

본 연구에서는 평면배열 수중 음향 트랜스듀서 내 소자들간의 상호간섭을 저감시키기 위한 다양한 구조적 방안을 제안하고, 각 방안의 효용성을 유한 요소해석을 통해 분석하였다. 그 결과, 소자들 사이의 커프의 깊이는 깊을수록, 커프의 너비는 넓을수록, 커프 충진재의 탄성계수는 낮을수록 상호간섭 저감 효과가 높게 나타났다. 본 연구의 결과는 평면배열형 수중 음향 트랜스듀서의 성능을 극대화시키기 위한 구조 설계에 유용하게 사용될 수 있을 것으로 기대된다.
