The flange thickness and rim inside thickness of the wheelset are key parameters that influence the wheel-rail contact. With the speed continuous increase of the rail vehicles, the wear of wheelset is becoming more and more serious, thus accelerating the changes of wheelset's flanges, which will certainly bring security hidden troubles to the operation of railway, so it is very important to realize...
Rail track geometric parameters, such as gage, level, longitudinal and alignment etc., have much influence on the operation safety of train vehicles. In this paper, a new measurement system for track geometric parameters is described. The measurement system is based on the three-point method for the straightness measurement, it uses laser sensor of displacement to collect data, uses notebook to process...
