Loading method and loading device for static test of undercarriage wheel

Abstract

The invention provides a loading method and a loading device for a static test of an undercarriage wheel. The loading device comprises a fixture, a clamping assembly, a vertical loading assembly, a side loading assembly and a navigation load assembly. The vertical loading assembly is vertically arranged and is connected with the fixture and the clamping assembly; the clamping assembly is installedat the corresponding position of the fixture through a connecting support; the side load assembly and the navigation load assembly are both horizontally arranged on the fixture, the side load assembly is arranged on two opposite sides of the bearing assembly, and the navigation load assembly is arranged on one side of the bearing assembly and is perpendicular to the side load assembly; loading points are arranged at the two ends of the bearing assembly, the two loading points are connected with the side loading assembly, or one of the loading points is connected with the navigation load assembly. Compared with the prior art, the loading device has the advantages that the real working condition can be better restored, and the obtained test data are real and effective.

Description

technical field [0001] The invention relates to the technical field of general tests, in particular to a loading method and a loading device for a landing gear wheel static test. Background technique [0002] With the rapid development of my country's aviation technology, the performance of aircraft has been continuously improved, and new and higher requirements have been put forward for the performance of aircraft wheels of aircraft landing gear. In order to verify the design and manufacturing strength of the wheel before the aircraft test flight, it is necessary to conduct a static test on the wheel. In the static test wheel loading device, the real radial load condition and radial-lateral combination of the aircraft wheel are simulated. Load conditions, verify whether the static strength and stiffness of the main engine wheel and brake device structure meet the design requirements, verify the rationality of the structural design and strength design of the landing gear whe...

AI Technical Summary

Problems solved by technology

At present, the general static radial loading test of the wheel only considers the design radial load of the wheel, but when the real landing gear lands, the wheel is not only required to be able to withstand the maximum radial load, but also required to be able to rotate flexibly on the ground , therefore, the current loading device can not meet the test requirements and standards

[0004] For example, the frame-type catapult take-off carrier-based aircraft front landing gear static test loading device disclosed in the current patent announcement number CN103604619A is applied to the landing gear static test loading device in front of the frame-type catapult take-off carrier-based aircraft, and the test conditions have limitations. , cannot solve the problem of real simulated landing gear wheel loading under different test requirements
