Abstract
In order to detect the diameter of a wheel-set online, the diameter was detected by using a laser displacement sensor and two eddy current displacement sensors at a speed of 15km/h. The weight of the wheel -set caused extrusion of the rail and changed the original measuring position, which had severe influence on the measuring results, so the influence of the deformation of the rail is analyzed and a compensation method based on the detection of the settlement of the rail is proposed. After compensation, the errors of the results are within ±0.5mm and the standard deviation is 0.12mm. The measuring results showed that the compensation method satisfied with the need of measuring accuracy.
