Evaluation of the L sub 10 Life of Military Greases in Wheel Bearings by Computer Analysis.

Abstract

The objective of the wear life study was to develop a methodology that would be capable of predicting performance of military grease under laboratory environment. The desired methodology can be used to reduce the current maintenance costs and to improve future systems. In the initial study, the maximum likelihood (ML) computer program for the two-parameter Weibull probability distribution has been developed on the failure data of grease. The results show that this computer program can reliably predict log life which can also be denoted as the minimum life of greases. Originator-supplied keywords include: Log life of grease, Weibull distribution, Maximum likelihood computer program, Extreme value distribution, Endurance test method, Newton-Raphson method.
