Paper Abstract

The geometric parameters of wheelsets, such as flange thickness, and rim width, and rim inside distance, are key parameters that influence the wheel-rail contact. The online measurement techniques of these parameters are important to ensure the safety of train vehicle and increase the reliability and efficiency of maintaining. The paper purposed the measurement system based on the optoelectronic techniques. The measuring system is composed of the trigger sensor and the laser displacement sensors fixed on the rails and the system can measure the wheelset's parameters when trains pass through. The measuring results are improved by the wavelet analysis denoised. The average value difference is between 0-0.3mm comparing the system and the manual that shows two methods are coincided. When trains pass through the measuring system under the speed of 10km/h, measuring results shows that the system can meet with the measuring requirement on line.
