레일조도 자동탐지 시스템 설계 및 측정시험

초록

In this study, we presents the signal analysis of an acoustic measurement device for rail. In order to reduce rail noise, measurement process are essential. Based on the design of the CAT3, the device including the actuation module has been developed. Acoustic roughness signals from the accelerometer attached at the end of cantilever beam are analyzed with steel plate thicknesses and operating speed of device. We verified the harmonic frequency by rail roughness.
