Vibration-based condition monitoring of rotary machinery develops toward application for highly non-stationary operational conditions, mainly rotational speed and load. If speed and load vary during the acquisition of vibration signal, both, instantaneous amplitudes and instantaneous frequencies of signal components vary accordingly. This scenario causes a strong demand for novel signal processing...
In this paper, the authors propose a method for extracting second-order cyclostationary components from a vibration signal. For a known cyclic frequency, the proposed algorithm allows to estimate the amount of energy of each cyclic component of interest in the time–frequency domain. In this way, the resulting representation contains only the chosen second-order cyclostationary component that manifests...
