Technique of Major Defect Detection in Railway Wheels by Results of Their Natural Oscillation Frequency Measurements

V. I. Kugushev

The technique of crack detection in railway wheels while operating is stated. The technique is based on a replacement principle of wheel natural frequency by other frequency derived as a result of random natural frequency damping with cracks. Graphical form represents normal wheels areas according to natural frequency spectrum. Examples of frequency spectrums of wheels with cracks are given.
