Phase-based time domain averaging (PTDA) for fault detection of a gearbox in an industrial robot using vibration signals
TL;DR: The proposed phase-based time domain averaging (PTDA) method can estimate deterministic signals that are more synchronized by considering the phase angle of the vibration signals and improve the performance of fault detection for gearboxes in industrial robots.

A positive energy residual (PER) based planetary gear fault detection method under variable speed conditions
TL;DR: The proposed positive energy residual (PER) method is capable of detecting faults of a planetary gear under variable speed conditions, while showing better performance than the two other methods.

A health-adaptive time-scale representation (HTSR) embedded convolutional neural network for gearbox fault diagnostics
TL;DR: Wang et al. as discussed by the authors proposed a health-adaptive time-scale representation (HTSR) embedded CNN, which is designed to exploit the concept of TSR, informed by the physics of the time and frequency characteristics induced by the faultrelated signals.
