Ezperimental Study on Mechanical System Torsional Vibration Based on Sensorless Detection Method
In order to study the mechanism and the effect of the sensorless detection method which is applied to mechanical system torsional vibration detection, a shafting torsion vibration simulation device was set up, which is driven by an induction motor and is loaded by a DC generator. The shafting torsional vibration is generated through the rapid on-off of a computer control load circuit. Then fault information is extracted from current signals by Hilbert transform envelope spectrum to compare with the traverse vibration signal measured by an eddy current sensor. The experimental results show that the mechanical fault information of the motor driving equipment, which is mainly a form of torsional vibration, is coupled to stator current. Compared to traverse vibration detection, sensorless detection method is more applicable to torsional vibration fault detection and diagnosis of the mechanical systems.
