[Abstract]:At present, in order to test the durability and reliability of aero-engine during its service life, an accelerated task test technology for aeroengine is proposed. However, accelerated task test technology is still in a period of development and perfection in our country. This paper studies the compilation and verification of aero-engine acceleration task test spectrum, and aims at the main components of aero-engine. Life tests carried out, Based on the existing engine load spectrum compilation techniques, a universal standard test load spectrum compilation method is proposed to simplify the process of load spectrum compilation under test conditions, based on which the general standard test load spectrum compilation method is proposed. The life test load spectrum of main engine components can be obtained conveniently and quickly. The specimen spectrum load test of accelerated load spectrum and original load spectrum under C is carried out. Based on the original stress spectrum of high pressure turbine disk of a turboshaft engine, the test temperature of 650? The accelerated stress spectrum under C and the two kinds of load spectrum are used as the experimental load spectrum to carry out high temperature 650? The creep-fatigue interaction test of the specimen under C condition. The comparison and analysis of the acceleration load spectrum and the original load spectrum are carried out to verify the equivalence of the two kinds of load spectrum and the feasibility of the method for compiling the accelerated task test spectrum. At the same time, the accuracy and validity of the universal standard test load spectrum compilation method are verified. By comparing the acceleration load spectrum and the original load spectrum with the acceleration task test spectrum and the simulated task load spectrum of a turboshaft engine, the results are compared and analyzed. The equivalence of load spectrum between accelerated task test and simulated load spectrum of a turboshaft engine is verified, which can be used as a reference for accelerating task test. Based on the GUIDE function of MATLAB software, a load spectrum management system software for accelerated life test is developed. Using this software, the acceleration task test spectrum of a turboshaft engine is compiled, and the actual use of the engine is fully considered in the process of compiling the software. Using this software, the acceleration task test spectrum of an aeroengine can be obtained conveniently and quickly. It saves a lot of money and time for aero-engine acceleration task test or parts test.
