【Abstract】 It was described of the technique of determining the correlation dimension of the vibration signals of reciprocating compressors using the embedding phase space reconstruction method. More visual and reasonable delay time could be selected with the combination of the self-interrelated function method and the pseudo phase portrait method. The scale range was given based on the reconstruction of vibration signals. The application of the technique in the fault diagnosis of reciprocating compressors verified its accuracy and efficiency.更多还原
