Abstract

The invention relates to the technical field of turbine blades, and provides a method for predicting the influence of an air film hole arrangement mode on the performance of a nickel-based single crystal alloy. The method for predicting the influence of the air film hole arrangement mode on the performance of the nickel-based single crystal alloy comprises the following steps of simulating a turbine blade provided with a plurality of air film holes, wherein the turbine blade is made of the nickel-based single crystal alloy; determining the maximum slitting stress borne by the turbine blade; determining the normal form equivalent force borne by the turbine blade; and determining the stress-strain distribution of the turbine blade according to the maximum cutting stress and the normal form equivalent force, so that the accuracy of performance prediction can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of turbine blades, and in particular to a method for predicting the effect of air film hole arrangement on the performance of nickel-based single crystal alloys. Background technique [0002] The turbine blade is a nickel-based single crystal alloy component, which can directly use high-temperature, high-speed gas to do work. In order to cool the turbine blades, air film holes need to be provided on the turbine blades. Among them, the arrangement of air film holes has a certain influence on the performance of the turbine blade. [0003] However, when predicting the performance of turbine blades in the prior art, a turbine blade model that omits air film holes is often used, and the influence of air film holes is not considered, resulting in inaccurate prediction results. [0004] It should be noted that the information disclosed in the above background section is only for enhancing the understandi...
