| Abstract: | The evidence fusion diagnosis method of wear out fault Dempster-Shafer for an aeroengine was investigated based on the spectrum information and the fault recognition framework and the fault diagnosis rules were determined.The mass function form was determined by using the section S function.Seven metallic elements informations of the density and rate of density change were fused in the fluid which was applied to wear out fault diagnosis for the aeroengine. |
| Keywords: | D-S evidence combination information fusion aeroengine fault diagnosis |
