Recently,A new research pointed that multipurpose lubricants can't provide satisfactory service in current demanding environments。Lubricant performance must be optimized to meet the increasing demands of modern industry.
The first step in selecting the best lubricant for a given application is to define the tribological system.With a fully defined tribological system in place,the next step is theoretical analysis.Selection of a lubricant based on EHD(Elastohydrodynamic) lubrication analysis or analysis of any other discrete parameter is inappropriate ,because such analyses focus only on a subset of the tribological system.
