摘要

For the deviation of replacing the actual physical model with the surrogate model in the probability analysis of the turbine disk life, an uncertainty evaluation method of reliability calculation of turbine disk life considering the geometric parameter dispersion and surrogate model error is developed. The main approach of this method is to quantify the maximum fluctuation range of the prediction life of the surrogate model and the maximum fluctuation range of the prediction life deviation between the surrogate model and the life model. The safety margin of turbine disc life is calculated and evaluated. Finally, the quantitative evaluation of uncertainty of the low cycle fatigue life of the engine GH720Li turbine disk is completed by this method.
