An anomalous frequency band identification method utilising available healthy historical data for gearbox fault detection

Schmidt, Stephan; Gryllias, Konstantinos C. (Elsevier, 2023-11)

Informative frequency band identification methods are used to automatically design bandpass filters to enhance fault signatures in vibration measurements. Blind and targeted features can be used to guide the frequency band ...
Combining an optimisation-based frequency band identification method with historical data for novelty detection under time-varying operating conditions

Schmidt, Stephan; Gryllias, Konstantinos C. (Elsevier, 2021-02)

Incipient damage detection is important for critical rotating machines such as gearboxes found in the power generation, mining and aeronautical industries. However, the fault information frequently manifests in weak frequency ...
