Based on Bayes estimation and Monte Carlo simulation method, a new method of getting distribution of fatigue strength parameters including average and dispersion is presented. With the scanty life date obtained by up and down experimental method, the interval estimation and confidence analysis of the parameters can be carried out, which makes the further study possible. A calculation example is also presented to validate the feasibility of this new method. Through comparison the results, the advantages and disadvantages of the three treatment methods of life date gained by up and down method can be easily seen.
