Vibration Monitoring of a Rotor System using RMS Accelerations (m/s2)

摘要

Vibration monitoring is a useful technique for application to rotating machines and provides valuable information regarding symptoms of machinery failures which in practice may avoid costly breakdowns. This paper involves design and fabrication of a rotor rig and investigations of vibrations at the bearings of the rig due to the effect of simulated faults, the test rig is designed in case of dynamic loading and also includes the various component used and fabrication of rotor rig The line diagram and actual photo graphs of Rotor Test Rig are also include in this paper. The faults like parallel misalignments, angular misalignment, combined parallel and angular misalignments and unbalances have been simulated. To study the effects of simulated faults, RMS (Root mean square) vibration accelerations in vertical, horizontal and axial direction of the rolling element bearings have been monitored using a piezoelectric accelerometer.
