摘要:Shield machine is a complex large-scale tunnelingequipment with multiple systems and driving sources. In orderto improve the accuracy of fault diagnosis for shield machine, amethod based on the combination of reverse feature elimination(RFE) and extreme learning machine (ELM) is proposed. Forthe characteristics of shield machine operation data with manydimensions and large quantity, the RFE method is introduced toreduce the dimension of the data, eliminate the redundantdimension and remove the correlation between features. Toimprove the accuracy and efficiency of fault diagnosis, the ELMneural network classifier model is built based on the extremelylearning mechanism for fault diagnosis of shield machine. Thesimulation results based on the field construction data showthat this method improves the accuracy of fault diagnosis ofshield machine significantly and has good engineeringapplication value.
