도시철도 소음저감을 위한 MFI(Multi Fluid Injection) 시스템 개발 및 효과에 관한 연구
A Study on the Development of MFI(Multi Fluid Injection) System and its Effect to Reduce the Noise of Subway
초록
The noise of the subway has become a social issue and includes very complex reasons. The friction between rail and train wheel is the most important reason of the noise. In this study, we developed MFI(Multi Fluid Injection) System which sprays the mixed fluid(water, anticorrosive and lubricant) on the rail when the train is approaching to reduce the friction. To verify the system's effect, we measured the internal and external noise of the running train. The measured and analyzed results show that MFI system reduce the noise of the running subway.
