    Abstract
  • By means of the rank statistical method and the mean ranks of the incomplete fatigue life data, the distribution parameter estimation formulas are derived. After the mean and the standard deviation of the population distribution are deduced, the confidence limit of the incomplete fatigue life is presented according to t-distribution theory. Two application examples of this method for the fatigue life prediction of the composite rotor and the rotor component in engine are given. In these examples, the results determined respectively by this method and the supposed complete life method are compared, and it is found that the safe life determined by this method is longer since the information of the incomplete life data is more fully used in this method.
