  • Gearbox fault identification under non-Gaussian noise and time-varying operating conditions 
    Schmidt, Stephan Stephan; Chaari, Fakher; Zimroz, Radoslaw; Heyns, P.S. (Philippus Stephanus); Haddar, Mohamed (Springer, 2021-05)
    The Synchronous Average of the Squared Envelope (SASE) is very useful to visualise the periodicities in the instantaneous power of the machine due to damage. However, the SASE is sensitive to impulsive noise and the presence ...
  • A simple condition monitoring method for gearboxes operating in impulsive environments 
    Schmidt, Stephan; Zimroz, Radoslaw; Chaari, Fakher; Heyns, P.S. (Philippus Stephanus); Haddar, Mohamed (MDPI Publishing, 2020-04-09)
    Reliable condition indicators are necessary to perform effective diagnosis and prognosis. However, the vibration signals are often corrupted with non-Gaussian noise and rotating machines may operate under time-varying ...
