Embodiment Construction

[0030] see figure 1 and figure 2 As shown, the overall static strength assessment test method of the main load-bearing parts of the aero-engine described in the present invention is completed by using the casing structure fatigue tester in the prior art. The casing structure fatigue tester includes a test console 26, a fixed base 9 and a test measuring mechanism. The first to seventh loading assemblies 5, 7, 8, 11, 12, 14, 16 are installed on the casing structure fatigue tester. The front end of the test assembly is connected to the front adapter section 8, the rear end of the test assembly is connected to the rear adapter section 13, the lower end of the test assembly is connected to the fixed base 9 through the main installation joint support 10, and the upper end of the test assembly is fixed to the auxiliary installation joint support 18 Plate 17 is connected and fixed on the casing structure fatigue tester.

[0031] Each loading assembly consists of 18 loading units, ...

Abstract

The invention discloses an aero-engine main force bearing component overall static strength assessment test system and an aero-engine main force bearing component overall static strength assessment test method. The aero-engine main force bearing component overall static strength assessment test system comprises a plurality of loading assemblies and a measuring mechanism, wherein adapting sections at left and right ends of a test assembly are connected with test frameworks through the plurality of loading assemblies, upper and lower ends of the test assembly are fixed on the test frameworks, the lower part of the test assembly is connected with the lower test framework through the fourth loading assembly, and the measuring mechanism is arranged on the right test framework and is connected with the test assembly. The test method provided by the invention has clear and feasible test steps and detailed loading process, can truly simulate working states of an aero-engine main force bearing component, applies complex load on the integral aero-engine main force bearing component synchronously on a test device, and is suitable for carrying out static strength assessment tests on various types of aero-engine main force bearing components integrally.

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 main load-bearing components of an aero-engine. 【Background technique】 [0002] With the continuous development of the modern aviation industry, it is necessary to carry out static strength assessment tests on the main load-bearing parts of the aero-engine to check whether the yield strength and ultimate strength of the main load-bearing parts in the working state and under the combined action of multiple loads meet the design requirements. Understand its failure mode. The load-bearing part is one of the important parts of the aero-engine, and it is an important part for supporting the rotor and fixing the stator. The thrust of the engine is also transmitted to the aircraft through the load-bearing components. [0003] Due to the complex structure and load of the load-bearing parts of the engine, it brings certa...
