An experimental study on angular misalignment detection in rotor bearing system using welch power spectral density

摘要

This paper describes Welch power spectrum density, a technique that monitors the functioning of rotor bearing system and the faults occurrence in operation environment. Vibrations in rotor bearing system have been measured fault detection with and without angular misalignment. It is difficult to predict in each mode of vibration and hence investigations on the vibration characteristics for the misalignment have to be determined so that down time can be eliminated to the possible extent. This study infers that the changed dynamic force induced at bearing depends on the localization and the magnitude of angular misalignment.
