레일표면 음향조도 측정 방법에 따른 계측 민감도 해석

초록

Rapid increase in railway transportation and train operation frequency is accompanied by railway noise issue. Therefore, it is important to investigate various sources of railway noise and to accurately measure and analyze rolling noise that occurs from contact mechanism between wheel and rail. In this paper, we developed new analyzing method in using auto-mobile measurement device to improve the accuracy of measured data. By using the proposed method, sensitivity analysis of the measured data have been performed and its results have been presented to verify the proposed method.
