The Analysis and Explore for Diagnosis of Fault Strength States of Rotator Based on Return Map

In the paper, we analyze and study the status character in detail which a rotor of some rotating mechanism exist in some different fault types and different fault strengths. The research result shows that a fault rotor reveals distinct return map images, which the rotor runs in different malfunction status or different malfunction strengths. The research gives an effective method to explore fault character of complex mechanism chaotic dynamic system.
