Gearbox condition monitoring and quality surveillance are crucial techniques to ensure safe and cost-efficient machine operations. In condition monitoring, the interpretation of the different vibration spectrum elements is still an open question, many works show that some predefined vibration models…
This paper presents a gradient-based method for on-the-fly optimization for both per-frame and per-frequency window length of the short-time Fourier transform (STFT), related to previous work in which we developed a differentiable version of STFT by making the window length a continuous parameter. T…
Demodulation consists in factorizing a signal as a product of a high-frequency component (carrier) and a low-frequency component (modulation). Most of the classical demodulation methods developed for telecommunications cannot be transposed directly on mechanical problems. In gearbox vibration monito…
