철도차량용 주름패널의 음투과특성에 관한 연구
A Study on the Sound Transmission Characteristics of the Corrugated Panels for railway Vehicles
초록
Sound transmission characteristics are investigated on the corrugated panels which used for railway vehicles. A special purpose program is developed to calculate the sound transmission loss of orthotropic multi-layered panels. Several kinds of corrugated panels are analysed to estimate the transmission performance and the results are compared with the measured data. Calculated transmission losses show good agreement with the measured values in corrugated panels and aluminum/foam multi-layered panels. The analysis results can be utilized to design the corrugated panels and multi-layered panels which are required to reduce the interior noise in railway vehicles.
