Research on screening method of performance index of PHM system for armored vehicles

Abstract

The comprehensive index system is a prerequisite and basis for ensuring the scientific performance of the product performance evaluation, so, the screening of the index is the necessary link in the construction of the index system. The paper regards the armored vehicle PHM system as a special product, aiming at the problem that the redundancy of the primary index set of the armored vehicle PHM system performance index system is high and the targeting is not strong. This paper uses Principal Component Analysis (PCA) to select the index, and then analysis of correlation between indicators and obtain the final optimal results. Finally, factor analysis is used to verify the feasibility and scientificity of the method, which lays a foundation for further evaluating the performance of PHM system.
