IMPROVED METHODS FOR THE
PREPARATION OF INITIAL DATA FOR THE DIAGNOSIS ALGORITHM PARAMETRIC
S.V. Yepifanov, B.A.
The correctness of the result of an object technical state
diagnosing depends on the effectiveness of the troubleshooting techniques, and
on the perfection of input data preparation. In this paper, a number of
improvements to the initial stages of the data preparation included in any
algorithm for parametric diagnosing. Particular attention is given to the most
crucial steps – selection of the
controlled area, the construction of the reference model, correction the
measured the parameters to the standard atmospheric conditions. A comparative
study of the effectiveness of various methods of smoothing the samples has been
done. The proposed method can be used equally well as in tolerance control, and
trends- analysis.
Key words: gas turbine engine, the parametric diagnostics, tolerance control,
trend analysis, calculated for standard atmospheric conditions, screening,
smoothing.
