투과손실을 이용한 틸팅차량의 실내소음 예측
Prediction of Interior Noise for Tilting Train by using Transmission Loss
초록
In this paper, we describe the analysis of interior noise for tilting train that is being developed in Korea. Tilting train is made of composite material to reduce the car body's weight and attached a self-steering system on bogie to improve curving performance. However, the acoustic performance (Transmission Loss) of such material is worse than the materials of conventional train, such as aluminum, steel and so on. Therefore, we measure the transmission loss of side wall / floor of tiling train and predict the interior noise for tilting train using its measuring results
