Combined platform for static strength test of rocket body structure

Abstract

The invention provides a combined platform for rocket body structural static strength tests. The combined platform comprises a main platform face and an axial force bearing platform body, wherein the center of the main platform face is of a through hole structure, and the axial force bearing platform body is detachably embedded in the through hole structure. The through hole structure comprises two concave arc surfaces which are symmetrically arranged and two inner arc surfaces which are asymmetrically arranged, and the concave arc surfaces and the inner arc surfaces are sequentially connected into a whole. The axial force bearing platform body is arranged on the concave arc surfaces of the main platform face and coincides with the center of the main platform face, two convex arc surfaces of the axial force bearing platform body are matched with the two concave arc surfaces of the main platform face, two round through holes are formed between concave arc surfaces of the axial force bearing platform body and the two asymmetrical arc surfaces of the main platform face, and the two round through holes are asymmetrical. The combine platform can be used for performing the axial asymmetrical load bearing test of a booster rocker and can also be used for performing the axial symmetrical load bearing test. The combined platform is simple in structure, convenient to operate, accurate in stimulation, flexible to apply and capable of being reused.

Description

technical field [0001] The invention relates to a rocket body structure static strength test platform, in particular to a rocket body structure static strength test combined platform capable of both axially symmetrical load bearing and dual engine axial asymmetric load bearing. Background technique [0002] For ordinary launch vehicles, the engine is located in the center of the rocket body, and the thrust generated by the rocket is along the axis of the rocket body, which is a symmetrical axial load. Therefore, the static strength test platform of the original rocket body structure is a test platform for symmetrical loads. With the increasing demand for the carrying capacity of the launch vehicle, it is necessary to use the form of bundled rockets to increase the thrust of the launch vehicle. At present, the common method is to use four booster rockets bundled to the main rocket. Each booster rocket will be equipped with Two engines, in order to maintain the balance of the ...
