| description | The invention relates to a planetary gearbox fault detection method and device, and a storage medium. The method comprises the following steps: obtaining a vibration signal of a planetary gearbox to be detected; calculating a theoretical value of the fault characteristic frequency of the gearbox; optimizing the parameter combination of the maximum correlation kurtosis deconvolution algorithm based on a sparrow search algorithm to obtain an optimal influence parameter combination; based on the optimal influence parameter combination, performing parameter optimization on a maximum correlation kurtosis deconvolution algorithm; obtaining a deconvolution signal of the vibration signal by using a maximum correlation kurtosis deconvolution algorithm subjected to parameter optimization; carrying out noise reduction processing on the deconvolution signal based on a sparse coding shrinkage algorithm; envelope demodulation operation is carried out on the noise reduction signal, and an envelope spectrum is calculated; an |
