APPARATUS FOR MEASURING SURFACE ROUGHNESS OF RAIL USING ACCELERATION SENSOR AND DISPLACEMENT SENSOR

摘要

Provided is an apparatus for measuring surface roughness of a rail while moving along, which may measure accurate surface roughness of the rail without any noise or error generated during the movement of the apparatus by using an acceleration sensor installed in a cantilever manner, and also may ensure more excellent accuracy and reliability of the measured surface roughness of the rail by using a plurality of displacement sensors whose locations may be adjusted.
