Fatigue Analysis, Blade Structure, Thermal Load, Finite Element Method


Engine turbine blades are subjected to cyclic thermal stress during engine start-up, shutdown and various operating conditions. These thermal loads may generate temperature gradients and tensions inside the blades, which may cause structural fatigue damage and failure, and in severe cases may directly lead to flight accidents. In order to ensure the integrity and reliability of the engine blade structure, the fatigue analysis of the engine blade structure considering thermal stress is of great significance for the safety of aircraft. In this paper, the fatigue life of the engine blade structure is simulated and analysed considering the thermal load. Firstly, the research background and current research status are briefly introduced, and then the relevant theories for fatigue analysis of blade structures are elaborated. Then, a three-dimensional engine blade structure model is built in CATIA software, and it is imported into ANSYS software for thermal stress analysis. On this basis, the thermal fatigue calculation of the blade structure is further done, and the fatigue life of the structure is obtained when the thermal load is considered.
