A Study Of The Condition Monitoring Of Large Mechanical Equipment Based On A Health Management Theory For Mechanical Systems

The condition monitoring (CM) of large mechanical equipment has previously been carried out based on the characteristics of the testing techniques, the test objects and the environmental conditions, without any type of guiding strategy. Therefore, in order to solve the problems encountered, this study first reviews the current definition, classification and common techniques of CM and puts forward a new definition for the method. Secondly, the study introduces the theory, content and implementation procedures of a proposed health management of mechanical systems (HMMS) monitoring method. Then, based on the above, the conditions of the proposed HMMS monitoring method are examined and the implementation procedures of the method are presented. It is concluded that CM should be carried out under the guidance of the HMMS theory and the key is to develop reasonable health management items and conditions for the monitoring parameters, as well as selecting the appropriate monitoring methods. Finally, two experimental applications of the proposed CM method based on the HMMS theory are carried out. The results obtained verify the feasibility of the proposed method, which provides a good reference for condition monitoring of similar equipment in the future.
