SURVEY OF LUBRICATION OIL CONDITION MONITORING, DIAGNOSTICS, AND PROGNOSTICS TECHNIQUES AND SYSTEMS

摘要

Recently, an increasing demand for performance assessment of lubrication oil has been noticed. Considerable techniques and systems in lubrication oil condition monitoring have been developed and successfully utilized in many applications such as gasoline/diesel engines, gearboxes and etc. This paper provides an overview of the existing lubrication oil condition monitoring solutions and their characteristics along with the classification and evaluation of each technique. The reviewed techniques are analyzed and classified into four categories: electrical (magnetic), physical, chemical and optical techniques. The characteristic of each solution and its sensing technique is evaluated with a set of properties which are crucial for oil health monitoring, diagnostics and prognostics. A comprehensive comparison among a wide ranges of different lubrication oil condition monitoring solutions are conducted.
