Niu Qiang · 2011
Aiming at the complex nature of the nonlinear existing in mine hoist fault time series,this paper uses the phase space reconstruction method to reconstruct the multi-dimension phase space for mine hoister fault time series.Based on chaos theory,the correlation dimension and the largest Lyapunov exponents are applied to analyze the features of mine hoist fault time series to realize the fault diagnosis for hoister.Research results show that mine hoist fault time series possesses chaotic characteristics,and the calculated correlation dimension and the largest Lyapunov exponents can be used for the characteristics in mine hoist fault diagnosis.
