Study on Mechanical Wear State in Military Launch Vehicle Hydraulic System with Knowledge Discovery from Analytical Ferrography

Abstract:

Knowledge discovery model of making-decision table was established based on rough set theory and the wearing characteristics of the military launch vehicles hydraulic system. Compatibility relationship of the incomplete information system was used to achieve knowledge discovery from decision-making tables. Incomplete information systems knowledge representation which based on attribute reduction had been simplified, it had obtained simple and intuitive decision rules. The rules indicated that only monitor the normal wearing debris and non-ferrous debris in hydraulic oil could determine the wear state of the hydraulic system.
