레일음향조도 탐지장치 설계를 위한 변위센서 데이터 분석

초록

For reduce rolling noise, we first need to measure and analyze the rail surface. Measuring devices include laser sensor, acceleration sensor or displacement sensor. In this study, we introduce the analysis of displacement sensor data by various parameters, spring stiffness, damping coefficient, and device’s velocity. These parameters affect impact force and its response displacement And we can confirm the analysis results through the octave band level graph.
