The vibration signal of rolling bearing on the driving side of dust-removing fan of Iron-making Plant is with such characteristics as strong nonlinearity and modulation due to it is in service in the harsh environment of high temperature, high humidity and much dust as well as the complex working condition of strong background noise so that its fault character frequency is difficult to be extracted and identified. With the variational mode decomposition (VMD) and maximum correlated kurtosis deconvolution (MCKD), the noise reduction and extraction of fault character frequency for vibration signal of rolling bearing for dust-removing fan are realized as well as the fault identification is completed by envelope demodulation.
