The invention relates to a vibration signal feature extraction method and device, a storage medium and computer equipment. The vibration signal feature extraction method comprises the following steps:collecting a vibration signal of target equipment; carrying out noise reduction on the vibration signal, so as to obtain a noise reduction signal; carrying out empirical mode decomposition on the noise reduction signal, so as to obtain an original intrinsic mode function corresponding to the noise reduction signal; acquiring a superposed signal according to the original intrinsic mode function corresponding to the noise reduction signal, and carrying out empirical mode decomposition and superposition removal on the superposed signal, so as to obtain a final intrinsic mode function corresponding to the noise reduction signal; and carrying out Hilbert-Huang transformation on the final intrinsic mode function, so as to obtain a spectrum signature of the vibration signal. According to the vibration signal feature extraction method, the feature extraction accuracy can be increased, and extracted features can well represent the operation states of the target equipment.
