Abstract
Aiming at the problem that the coupled bistable stochastic resonance (CBSR) is almost always a two-dimensional potential system, a three-dimensional coupled bistable stochastic resonance (TCBSR) system is proposed, which is composed of a fixed parameter bistable system coupled with two adjustable parameter bistable systems. Firstly, the fourth-order Runge Kutta is used to calculate the system output, and the influence of noise intensity and system parameters a, b, r on the output signal-to-noise ratio (SNR) is simulated and analyzed. Then, taking SNR as the objective function, the particle swarm optimization (PSO) algorithm is applied to search the maximum SNR and its corresponding optimal parameter pair. The bearing outer race fault experiment proves that the proposed adaptive TCBSR method can better suppress the interference in high frequency band and has stronger weak signal feature enhancement and fault detection ability than adaptive CBSR system based on PSO, which is conducive to the application of SR in engineering practice.
