METHOD OF NONCONTACT DYNAMIC MONITORING OF ROLLING STOCK WHEELS PARAMETERS Russian patent published in 2006 - IPC B61K9/12 G01B11/24 G01B11/10 

FIELD: transport engineering; rail vehicles.

SUBSTANCE: invention relates to measuring facilities and it can be used for checking condition of rail vehicle wheels 1. According to propose method, axle-box of wheel 1 to be checked and rail 3 with contrast mark 9 are exposed to flow of radiation, and image is received by radiation receiver. Radiator and matrix receiver are placed at a distance from rail track. Axle box and rail are irradiated with flow in form of train of short pulses with frequency proportional to wheel speed. Position of maximum of correlation functions obtained at correlation of standard fragment of image of axle box or rail mark with image in current frame is determined and changes in radii and parameters of wheel are judged by changes of vertical coordinates of maxima of correlation functions of axle boxes and rail in image frames.

EFFECT: improved reliability, enlarged functional capabilities.
