| Abstract: | On the basis of the statistical characteristics of fatigue cumulative damageand its critical value, a new dynamic interference model for reliability analysis is presented. Because the nonlinearity of fatigue damage accumulation is taken into account,this model is able to predict the fatigue reliability for random spectrum loadingconveniently. To verify the predicted results, a special fatigue expenment, in which thenumber of specimen is up to 101, is conducted using a fighter spectrum loading. It isshown that the new model is reliable, practicable and better than existing models. |
