Abstract

In this paper, the interface matrix of honeycomb composite panel has been derived by the governing equation of a honeycomb sandwich panel. The interface matrix of honeycomb panel is added to the previously developed transfer matrix method, thus analysis of the multi-layered insulation composite panel with honeycomb is accomplished. Furthermore, predictions of sound transmission loss(STL) for the ship's insulation panel with honeycomb and mineral wool are presented. The insulation performance of the honeycomb used for skin of the ship's insulation panel is better than that of 0.35 mm steel panel by 2dB, approximately. Although honeycomb panel has inefficient insulation performance beside steel panel, honeycomb panel achieve improvements in the performance of weight reduction. The surface density of the panel with honeycomb is rather than with steel by $5.2kg/m^2$. It is decrease in weight by 31.7 %.

본 연구에서는 허니컴 패널의 지배방정식을 이용하여 경계행렬식을 유도하였고, 이를 전달행렬법에 적용하여 허니컴 패널을 적용한 차음패널에 대한 해석 이론을 정립하였다. 또한, 허니컴 패널을 선박용 차음패널의 표면재로 적용하여 차음성능을 분석하였고, 철판을 표면재로 적용한 기존의 선박용 차음패널과 차음성능을 무게 당 감음량 기준으로 비교 분석하였다. 그 결과, 허니컴 패널의 차음성능이 0.35 mm 철판에 비해 STC 기준으로 2dB 높게 나와 허니컴 패널을 적용한 차음패널의 차음성능이 철판을 사용한 차음패널에 비해 무게 당 감음량을 고려할 시 우수하다는 것을 확인하였다. 또한, 허니컴 패널을 표면재로 사용한 차음패널의 면밀도가 철판을 사용한 차음패널에 비해 약 $5.2kg/m^2$ 가볍게 나타났고, 이는 약 31.7 % 무게 감소를 의미한다.
