Abstract

The aim of the paper is to present an application of the WT analysis of vibration signals recorded during the run-up or run-down of rotating machinery. Because of complex research work and complicated signals structure the described experiments need an application of special methods. The very good results have been achieved with the use of the WT analysis. However, it demanded special way of synchronization of analysis parameters as well as choice of basis functions. The results of the WT analysis are very interesting, but at the same time their interpretation is very difficult. There is shown an application of the RSL method in the paper. Its application leads up to partitioning of some signal components. This method can be applied to results of the WT analysis, which facilitates the interpretation of scalograms. Identification of these components with diagnostic knowledge is the base of estimation of phenomena occurred during machinery operation thereby technical state of machinery.
