Problems solved by technology
[0003] Due to the complex structure and load of the load-bearing parts of the engine, it brings certain difficulties to the structural design and strength calculation of the load-bearing parts. It often needs to be verified by tests, which must be verified by tests. Due to the experimental conditions and the development needs of the engine , the existing tests cannot meet the test requirements for the coaxiality, stiffness, deformation, yield strength and ultimate load of the main load-bearing parts of the engine. This test is the first test project carried out in China, and there is no reference method at home and abroad. And technology

Description
【Technical Field】 [0001] The invention belongs to the field of aero engine testing, and relates to an overall static strength assessment test system and method for the main bearing components of the aero engine. 【Background technique】 [0002] With the continuous development of the modern aviation industry, it is necessary to conduct a static strength assessment test for the main load-bearing components of aero-engines to assess whether the yield strength and ultimate strength of the main load-bearing components meet the design requirements under the combined action of multiple loads. Understand its mode of destruction. The load-bearing component is one of the important components of aero-engines, and is an important component supporting the rotor and fixed stator. The thrust of the engine is also transmitted to the aircraft through the load-bearing components. [0003] Because the structure and load of the engine load-bearing parts are relatively complex, it brings certain diffi...
