Derivation and measurement of DFR based on Gerber model under corrosive conditions
In order to study the influence of the selection of the equal life curve model on the calculation results of the detailed fatigue rating, the fitting precision of the Gerber model and the Goodman model for the high-cycle fatigue data was compared for six typical aeronautical materials.

| description | In order to study the influence of the selection of the equal life curve model on the calculation results of the detailed fatigue rating, the fitting precision of the Gerber model and the Goodman model for the high-cycle fatigue data was compared for six typical aeronautical materials. The DFR calculation based on the Gerber model was derived. Formula, expression of corrosion conversion coefficient CC; fatigue test for pre-corrosion 0 h, 6 h, 12 h, 24 h, 36 h and 72 h for 2024-T3 aluminum alloy (surface anodization) and analysis of pre-corrosion 72 h fatigue fracture. The results show that the Gerber model is suitable for aluminum alloys such as LY12CZ, and the DFR method based on the Gerber model can exert the potential of ductile materials when N95/95 > 105 times; with the increase of pre-corrosion time, 2024-T3 aluminum alloy DFR The values decreased, and the DFR calculated based on the Gerber model were 84.251 MPa, 84.721 MPa, 79.683 MPa, 80.745 MPa, 77.026 MPa, and 74.996 MPa, respectively.
