Abstract

The herein described subject matter relates to a method and a diagnostic device 10 for precisely and reliably diagnose mechanical failures of rotating components in a railway vehicle 1 by precise determination of the characteristic frequencies of the rotating components. To determine the characteristic frequencies of a rotating component, the rotation frequency of the respective component is required. This rotation frequency is calculated based on the vehicle speed and the diameter of the wheels 7, 7a, 7b of the rail vehicle 1. In order to improve the accuracy of said rotation frequency determination, the wheel diameter is measured regularly at predetermined intervals.
