Transmission loss of Honeycomb Composite Panel of the Tilting Train
틸팅 열차용 허니콤 복합판재의 투과손실

Abstract
In a tilting train, aluminium honeycomb composite panel is used for the high speed and light weight. Side wall of the tilting train includes the composite panel of carbon fiber, aluminium honeycomb and epoxy fiber as a main structure. In this study, we measure the transmission loss (TL) of the honeycomb composite panel and analyse the sound insulation performance by using the orthotropic plate model. We investigate experimentally how the air gap, plywood and glass wool improve the sound insulation performance of the composite panel. The purpose of the study is to provide practical information for the improvement of TL of the honeycomb composite panel used for the tilting train.
