Abstract

A method for detecting defects of a wheel (20) of a railroad vehicle comprises: determining an instantaneous angular speed signal (30) of a shaft (14) connected to the wheel (20), wherein the instantaneous angular speed signal (30) is determined from measurements of a speed encoder (22) connected to the shaft (14) and wherein the instantaneous angular speed signal is indicative of a speed of the shaft (14) at a rotation angle of the shaft (14); determining at least one amplitude (32) of a frequency component (34) of the instantaneous angular speed signal (30) seen as a function of the rotation angle; and detecting a defect based on a magnitude of the at least one amplitude (32).
