Development of diagnosis algorithmsfor technical objects of different purpose
The paper describes the main steps of development of diagnosis algorithms for complex technical objects for which new generation diagnosis systems are expected to be designed. Previous diagnostic systems were mainly designed for non-destructive testing. However, non-destructive testing is not sufficient to adequately determine residual life of test objects. The in-service condition monitoring accuracy of components and systems can be improved if they are designed with features allowing acquisition of the most informative condition measurements. In view of this, diagnosis algorithms for new technical systems should include modules capableof selecting the most informative diagnostic indicators that can be obtained during diagnostic measurements. A special attention should be paid to the issues of uncertainty assessment of direct and indirect measurements because these issues are not completely resolved in metrology standards.
