Description

technical field [0001] The invention relates to the technical field of aerospace mechanics testing, in particular to a static test device and method for simulating a wall plate structure of a cylindrical cabin section. Background technique [0002] Cargo spacecraft, space stations and other large spacecraft are mostly cylindrical cabins, and the cargo warehouses or instrument cabins inside the cylindrical cabins are all made of multi-layer wall panels. In order to ensure the structural reliability and stability of the spacecraft during use, the structural design of its bearing capacity is the primary goal. In the development process, it is necessary to simulate the load-bearing form of the spacecraft under laboratory conditions, and to assess and verify its structure. [0003] During the static test, due to the limitations of the internal space of the cylindrical cabin and the conditions of the test simulator, the static test and the actual load-bearing form of the cylindri...

AI Technical Summary

Problems solved by technology

Under the same load conditions, different design forms of tooling and simulation devices lead to distortion of the force transmission path, resulting in partial over-examination of the cabin structure or under-examination of the panel structure. To ensure the load-bearing assessment of the inner panel structure of the cylindrical cabin, it is necessary to use High reliability and precision simulation device for static test

[0004] In the prior art, there is no simulation device specially used for the static test of the cylindrical cabin panel structure. Usually, the real panel structure is used for the test, so the processing cycle and cost usually cannot meet the test requirements. Therefore, it is necessary to design In consideration of various aspects such as processing, materials, etc., a static test simulator suitable for the columnar cabin panel structure is designed to simulate the load-bearing assessment of the columnar cabin panel structure in the static test
