동력 분산형 고속철도 차량의 실내소음 해석 : SEA 응용
Analysis of Interior Noise of High Speed EMU by using SEA
- 발행 : 2010.06.10
초록
In this study, interior noise of the high speed EMU was estimated by statistical energy analysis (SEA) method. Based on the data measured at a distance of 25m from a running train, exterior noise of the running train was calculated. And then it was designed as noise sources in VA ONE, a commercial software of SEA. coupling and damping loss factor of high speed EMU studied in previous studies is used. The interior noise of the train was estimated for a open-land section. The analysis of interior noise of HST in the tunnel section will be estimated through same method.
