The paper presents a multidimensional model of stochastic vibration signals in the form of interrelated periodically correlated random processes. Algorithms were analyzed, and software was developed for computation by experimental data of mutually spectral density and mutually spectral components of periodically non-stationary random vibrations, as well as time-averaged and componentwise coherence functions. Technical characteristics of the developed vibrodiagnostic system PULS with controllable frequency characteristics are given. Results, obtained with application of this system during performance of vibratory analysis of industrial facilities of Ukraine, are considered.
