| Abstract: | Typical riveted structure samples were designed and the ground parking environment of aircraft on-service was simulated.Pre-corrosion test under accelerated corrosion test environment spectra and constant-amplitude fatigue test after different corrosion time were carried out.Finally,the fatigue life characteristics on pre-corroded typical riveted structure was obtained,and the effect coefficient C(t) curve of ground parking corrosion to fatigue life was established. |

| Keywords: | fatigue life pre corrosion C（t） curve |
