Abstract EN
The degradation state identification is a key step of the condition based maintenance of hydraulic pump.
In this paper, spatial information entropy (SIE) as a novel degradation feature of pump is proposed based on the study of permutation entropy (PE) algorithm.
The fundamental principle of SIE is introduced and contrasted with PE.
Different parameters used in the calculation of SIE are discussed and meaningful conclusion is gained.
The results of simulation analysis not only checked the rationality of SIE but also demonstrated the availability and superiority of adopting SIE as the degradation feature.
Based on simulation analysis, SIE and PE are united and used as degradation feature vector of pump.
FCM algorithm is employed to diagnose the degradation state of pump.
The analysis results of practical signal testified the rationality and availability of the proposed method.
