Vibrations of industrial structures - Tools and experimental analysis methods

Following the articles [R 6 190] Vibrations of industrial structures. Notions de physique des vibrations and [R 6 191] Vibrations des structures industrielles. Tools for modeling, prediction and interpretation, this text describes analysis and post-processing tools.

The term "post-processing" implies that the original signals are acquired during the test and stored in memory, so that they can be analyzed and the results interpreted. The storage stage can be avoided in certain repetitive cases of well-established on-line processing, but in periods of trial and error (when the analysis protocol has yet to be perfected), it is preferable - or even essential if the experiment cannot be reproduced - to have all the information acquired during the original trial available for off-line processing.

Please note that a number of real-life case studies will be detailed in the article [R 6 194] Vibrations in industrial structures – Controlling vibrations and induced noise – Industrial case studies.

Finally, please refer to the article [R 6 193] Industrial vibration sensors to find out which vibration sensors are the most appropriate in each context.
