The anti-fatigue design method of aerospace thin spoke plate is discussed. The determination of the stress spectrum of the thin spoke gear plate, the stress analysis of the finite element method and the relevant treatment method in the fatigue life estimation process are given. The comparison between the analysis results and the experimental results shows that the anti-fatigue design method of the thin-walled gear presented in this paper is effective
