The Study of Fault Diagnosis Method Based on Chaos Characteristics
Based on chaotic characteristics of vibrating screen sides in vertical direction, the paper used phase space reconstruction theory to calculate the characteristic parameters of vibration signals, which are correlation dimension and Lyapunov exponent. Through experimental research, it was found that there was obvious difference in Correlation dimension and Lyapunov exponent when of vibrating screen has crack and has no crack. The characteristic parameters of vibration signals can be used as the basis to determine vibrating screen has crack or no crack. Using this method for fault diagnosis is simple, intuitive, and convenient for analysis.
