Thermal mechanical and high-cycle composite fatigue test method for turbine blade in rotating environment

The invention provides a thermal mechanical and high-cycle composite fatigue test method in a turbine blade rotating environment, and solves the problems that the lifting of centrifugal force of a blade is simulated by utilizing the lifting of a stretcher, and the influence of blade rotation on vibration cannot be well simulated by superposed high-cycle fatigue vibration of a static blade which simulates the lifting of temperature by utilizing an induction coil. The method is carried out on a wheel disc rotation tester, the accuracy of the simulation environment is improved, the method can be used for testing and examining the blade body root section and the tenon root section, and key parts are examined. And thermal mechanical and high-cycle composite fatigue tests of a plurality of blades of the whole wheel disc can be carried out in one test, so that the number of sub-samples of the test is greatly increased, the accuracy of a test result is improved, the test time is saved, and meanwhile, the test risk in
