A Weak Signal Detection Method for Bearing Based on QGA and Stochastic Resonance

Aiming at the problems that the vibration signal is weak and the SNR is low in its early failure stage of rolling bearing, a weak signal detection method combining Quantum Genetic Algorithm (QGA) and Stochastic Resonance is proposed, which improves SNR and identifies fault location. Firstly, the lar...
