摘要

The paper introduces the concept of Instantaneous Circular Pitch Cycle Map (ICPCM) as a tool for analysis and diagnosis of modulation signatures in vibrations generated by Epicyclic Gearbox (EGs). The method is based on the representation of a vibration signal as a 3-D map illustrating selected signal properties. Within the method, a novel concept of a Resampling Relative Order (RRO) is introduced. The paper illustrates how the ICPCM might serve as an auxiliary tool for proper interpretation of spectra, envelope spectra, and time-synchronous averaged representations. The idea of the method is presented on a simulated signal, while its practical performance is illustrated on a real signal from a multi-stage EG. (C) 2018 Elsevier Ltd. All rights reserved.
