Paper Abstract

The aim of the paper is to introduce a description of a rotating machinery operation in variable conditions. The description was based on a dynamic scene idea. A diagnostic research of the rotating machinery conducted in variable conditions of its operation lets us to observe reaction of machinery on different kinds of excitations. An example of this research is run up or run down of machinery. In this case, the frequency range of excitations is very wide. Results of this research are great source of information on technical state of the observed machinery as well as changes of its technical state. Interpretation of time-frequency analysis results is nowadays based on the visual manners of their estimation. The paper deals with a way of description of the machinery operation in dynamic scene form, which was based on results of a time-frequency analysis of vibration signals recorded during machinery operation in variable conditions. The proposed manner of that description can be basis for automatic identification of technical state of the observed machinery.
