[0016] The present invention uses adaptive stochastic resonance based on artificial fish swarm algorithm to propose an adaptive stochastic resonance bearing fault detection method, which includes the following steps:
[0017] (1) Use the acquisition system to collect bearing fault signals;
[0018] Specifically, the acceleration sensor is fixed on the vibration table, and the vibration acceleration signal of the bearing is collected by the collection system, that is, the bearing failure signal.
[0019] (2) The bearing fault signal is transformed into a small frequency signal by the scaling method;
[0020] Specifically: According to frequency compression ratio Define sampling compression frequency , Is the actual sampling frequency of the fault signal; the numerical calculation step size obtained from the compressed sampling frequency is , So that each frequency component of the bearing fault signal (the characteristic frequency of the fault signal is ) Compression scale rati...
