Paper Abstract

The dynamic diameter measurement of locomotive wheels is important to ensure the vehicle safety. We propose that the diameter of locomotive wheels can be automatically determined by a one-dimensional displacement sensor and two eddy sensors which are installed on the inside rail. The distance between the laser displacement sensor and the wheels can be detected when the wheels pass through the center of the two eddy sensors. The diameter of wheels can be calculated. The experimental results show that the accuracy and repeatability can meet the need of measurement.
