레일음향조도 자동 측정장치 설계

초록

This paper presents a new design of an automatic measuring device of rail roughness. Rolling noise is one of the main cause of train noises, this noise is occurred by rail surface condition. In order to reduce the noise, the surface roughness condition of rails has to be measured. The newly designed device shows batter performance in view of the reduction of vibration and operating speed. The detailed design concepts of each part of the device are given. We explain purpose of the design and specification of each parts.
