Goals

Starting from the very old and still concept of monitoring and diagnosis by the ear of an experienced engineer, the required physical basis for vibration monitoring will be treated. Vibration patterns for typical machine faults will be explained together with analysis instrumentation.

Strategic Analysis

In parallel to the practical stuff, the basics of signal analysis will be explained from the very beginning in a theoretical part of the course, but this time as an easy to understand mathematical description of basic human perception. Names like Fourier or Hilbert will loose their frightening, cepstrum analysis and demodulation will appear as interdisciplinary analysis concepts. Sophisticated mathematical theories will be background and not the starting point and can be activated as required for deeper investigation. Regarding the powerful hardware and software tools on the market, this should be a very good concept, useful as a basis for the engineer for developing and testing his own concepts. A straight line will be drawn from very basics up to the most modern analysis procedures.

Economic strategies are very important today and will therefore also be treated during the course.

Aspects

From economic point of view, condition based machinery monitoring and early fault diagnosis are of growing interest. It is really an interesting but also challenging task for the mechanical engineer. Sophisticated technology of measuring and analysis systems and new procedures require fundamental and interdisciplinary knowledge to get a foothold in this area. A promising and fascinating field.
