Problems solved by technology

However, the traditional radiation heating test uses the single-side radiation heating method for thermal assessment, which is difficult to simulate the deformation coordination state in the thermal state, and is limited by the single-side radiation heating method, which has the problem of heat leakage from the test piece to the surrounding tooling and the influence of boundary effects. Larger, it is difficult to accurately simulate and control the thermal boundary, and cannot meet the assessment requirements of the above two aspects

Abstract

The invention provides a heat examining tester for a structure with pretightening force adjustment, and belongs to heat examining testers for heat sealing and insulation structures with pretighteningforces under effect heat deformation coordination. The tester mainly comprises a heating component, deformation coordinating plates, a loading device, an installation adjustment structure and pressuresensors, the two deformation coordinating plates are arranged in left-right symmetry, the loading device is mounted at one end of the two deformation coordinating plates, test members to be examined,bearing structures and pretightening force applying plates are successively arranged in the outer sides of the two deformation coordinating plates respectively symmetrically, the two pretightening force applying plates are compacted by the installation adjustment structure, and the heating component heats the test members to be examined in a non-contact way. Thus, pretightening force application,deformation coordination simulation and heating control are examined accurately by simulation, and the tester is suitable for heat examination test of the heat sealing and insulation structures withpretightening forces of a high speed aircraft.

Description

technical field [0001] The invention belongs to the technical field of thermal assessment tests, and in particular relates to a structural thermal assessment test device with preload adjustment for high-speed aircraft, which is applied to the coordination of deformation of structures with preload, such as heat-sealed structures and heat insulation structures of hypersonic aircraft. Thermal assessment test of friction and rubbing state. Background technique [0002] Due to the different working environment, material system, and structural form of the high-speed aircraft and its engine, the relative deformation in the working state is relatively large, and there will be a large deformation coordination problem between the two. Therefore, it is required that the connection between the high-speed aircraft and the engine can not only realize deformation coordination, but also ensure reliable sealing and connection. [0003] In order to realize the deformation coordination betwee...
