In connection with the nonlinear dynamic characteristics shown from the performance of fault rotating mechanical system, based on the research and analysis, correlation dimension and complexity can be used to characterize the system state of motion. The authors propose the analysis method of correlation dimension and complexity to the signal feature of mechanical fault. Using theory of phase space...
In connection with the nonlinear dynamic characteristics shown from the performance of fault rotating mechanical system, based on the research and analysis, complexity and approximate entropy can be used to characterize the system state of motion and non-degree rule. The authors propose to apply complexity and approximate entropy to the feature extraction of fault signal. From the analysis and calculation...
