According to real operating conditions of turbine engine blades in service
a series of combination tests of various load matching and frequency matching for plate specimens was carried out on the compound fatigue testing rig which can simulate operating loads on the blades.From the test results and theoretical analyses
some characteristics and the regularities of this compound fatigue are obtained.A new method of life prediction for this compound fatigue is presented in this paper.The calculated results of this method are in good agreement with the experiments.
