Abstract
As a part of conditional maintenance, rotating machines are monitored and diagnosed in real time to increase their service life and ensure their availability in the industry. Our work aims to follow the evolution of the vibration for rotating machines through the integration of inverse problems such as degradation of the lubricant quality. Experimental tests were made in order to characterize the influence of quality lubricant (viscosity) on the vibration of a component of a rotating machine. Realized experimental bench is composed of gear device lubricated with lubricants of different viscosity grades and rotated at a variable rotational speed. In each case we measure the value of vibration. Following this experience, a vibration model has been developed depending on the change of state of lubricants, based on the results of planned experience. Further, a correlation analysis on the model obtained was realized and the results show an agreement between theory and experiment.
