Abstract：In this paper, it constructs a non-Gaussian correction coefficient based on polynomial response surface model, and proposes a new method for fatigue life estimation under non-Gaussia- n random vibration. Transforming the non-Gaussian random stress into Gaussian random stress based on Winterstein transfer function method, estimating their cumulative damage and spectral moments based on rain-flow counting and Miner damage criterion, constructing a polynomial response surface model for stress spectral moments and non-Gaussian correction coefficient based on the method of least squares for many samples. Contrasting non-Gaussian random vibration damage based on Gaussian approximation and based on rain-flow counting and Miner damage criterion, the results shows that Gaussian approximation has better accuracy.
