The invention provides a method and device for determining the service life of a turbine blade, electronic equipment and a storage medium. The method comprises the steps that the gas compressor inlet flow, the gas compressor outlet pressure, the gas compressor outlet temperature and the turbine inlet temperature of a working gas turbine unit in different working durations are obtained; according to the inlet flow of the gas compressor, the outlet pressure of the gas compressor, the outlet temperature of the gas compressor and the inlet temperature of the turbine, temperature fields corresponding to different working durations of turbine blades in the gas turbine unit are calculated; determining a stress tensor matrix corresponding to the turbine blade according to the elastic matrix of the turbine blade, the temperature field corresponding to each working duration of the turbine blade and the blade rotating speed corresponding to the working duration of the turbine blade in the historical working process; and determining the service life of the turbine blade according to all the stress tensor matrixes and the stress service life formula. According to the method, the calculated amount can be reduced, and the time for determining the service life of the turbine blade is saved.
Description
technical field [0001] The present application relates to the technical field of turbine blades, in particular to a method, device, electronic equipment and storage medium for determining the life of a turbine blade. Background technique [0002] With the development of industry, gas turbines have also been applied to various fields, but during the start-up and shutdown of gas turbines, the load on the turbine blades in the gas turbine will shorten the service life of the turbine blades and reduce the reliability of the blades. Only by accurately predicting the thermomechanical fatigue life of the blade can the safety period of the blade be determined and the reliability of the blade can be guaranteed. [0003] In the prior art, numerical simulation is used to determine the life of turbine blades, and it is necessary to simulate the transient working process of the three major components of the gas turbine, namely the compressor, combustor, and turbine, to obtain the flow an...
