Simulation and Analysis on Typical Rotor Fault Based on DASP
TANG Yu, SHI Chengjiang, YANG Jing, CUI Qing
Based on the flexible rotor testbed as the research object, used DASPv10 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 timedomain analysis, frequencydomain 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.
