In order to further study the equivalent accelerated relationship, this paper summarized the existing research on corrosion damage equivalent methods, described the equivalent conversion methods in detail based on the electrochemi-cal principle, physical parameters and mechanical damage, and discussed the advantages and disadvantages of the various methods. The equivalent accelerated relationship research method based on electrochemical principle is suitable for develo-ping the accelerated test environmental spectrum for the metal structure of aircraft, the equivalent accelerated relationship research method based on physical parameters is suitable for establishing equivalent accelerated relationship of accelerated test environmental spectra for the fatigue key sites, the coating of the corrosion key sites and the metal matrix, while the mechanical damage comparison method is suitable for the key sites of structural fatigue. Finally the conclusion was drawn that different equivalent accelerated relationship should be adopted for different materials and different sites.
