N2 - A major challenge in fault diagnosis for rotary machines is the effective extraction of features from weak signals that are indicative of faulty components, submerged in strong noise. Unlike traditional techniques that focused on noise filtering and reduction, stochastic resonance (SR) takes a noise-assisted approach to detecting and analyzing weak signals. This paper presents a new method for weak signal detection, termed Dual-scale Cascaded Adaptive Stochastic Resonance (DuSCASR), in which the new adaptive strategy can quantify the frequency content of a weak signal without prior knowledge. Simulations and experiments have confirmed the effectiveness of the method in early stage bearing fault diagnosis under strong noise, with high precision and robustness.
