Correlation degree analysis of sliding bearing oil monitor data based on grey theory

Based on regular analysis of the spectrum, PQ value, precision moisture content and kinematic viscosity of a certain sliding bearing lubricating oil, this paper used grey theory to study the correlation degree within these four kinds of analysis indicators. It is hoped that it can achieve mutual verification and judgment of the state evaluation of sliding bearings. It can provides reliable basis for studying the internal operating rules of sliding bearings. It can also provide scientific basis for the management and maintenance of sliding bearings.
