Abstract477)      PDF (4664KB)(486)      
Based on the flexible rotor testbed as the research object, used DASPv10 analysis software to simulate the rotor imbalance and misalignment of two typical faults, the mechanism analysis were made for the collected signal from the eddy current sensor and the piezoelectric acceleration sensor. The experiments gave the timedomain analysis, frequencydomain analysis and axis path diagram in the case of normal and fault two cases,compared the experimental results with the theoretical analysis. It verified the two typical fault identification features of rotor vibration, making a better understanding of the fault mechanism and fault diagnosis of the rotating machinery system. 
