摘要
A cyclostationarity approach to the analysis of mechanical signals. Cyclostationarity offers a theoretical framework to processes whose statistical properties are periodically varying in time. It is found particularly relevant for analysing acoustical and vibration signals. This paper addresses the peculiarities of such an approach. Several examples illustrate its potential to the diagnostics of machines, the identification of mechanical systems and the separation of vibro-acoustical sources.
