Abstract
The fatigue analysis for civil aircraft wing skin butt joint in serving environment was processed. Considering the selected typical serving condition, the detail fatigue rating (DFR) ground-pre-corrosion-influence-factor and air-corrosion-fatigue-influence-factor were determined by detail simulation specimens tests in laboratory accelerated environment. The methods were presented to decompose the complex serving environment and to obtain DFR-corrosion-influence-factors of structural element by the factors gained by typical laboratory environments tests with detail simulation specimens. A corrosion-corrosion fatigue alternated experiment, corresponding to the selected serving condition, with typical wing skin butt joint simulation specimen was designed and conducted. The comparison of the analysis conclusion and the test result shows the validity of the method.
