Embodiment Construction

[0017] When the existing wood block / steel composite structure using machine-added symbols is bonded to the large-curvature radome, the adhesive that appears due to the unsatisfactory symbols cannot evenly fill the non-conformable area, resulting in the adhesion of the radome. The area of ​​large curvature that is not easy to fit is not sufficient, the combined structure of wood block / steel plate will fall off under the action of large load, and the radome will be damaged in layers when it is not uniformly subjected to large load. The purpose of the present invention is to more realistically simulate large curvature and large load radar Partial load loading of the hood ensures that the test load is applied evenly and ensures the accuracy and efficiency of the static test.

[0018] The invention proposes a full-fill bonding method suitable for bonding wood block / steel plate composite structures when loading large curvature and large load radome tests, which can solve the problem ...

Abstract

The invention belongs to the technical field of test mechanics, and particularly relates to a full-injecting type bonding method for a large-curvature large-load radar cover and a tension-pressing pad. The method comprises the following steps that a tension-pressing pad of model fitting is designed according to the shape of a radar cover loading area; a glue injection through hole is formed in thelarge-curvature position of the tension-pressing pad corresponding to the radar cover loading area; an adhesive is brushed on the bonding surface between the tension-pressing pad and the radar cover;adhesive glue is fully injected into a large-curvature area which is not ideal in model fitting through the glue injection through hole; and full-injecting bonding between the tension-pressing pad and the radar cover loading area is achieved after the adhesive is cured. According to the full-injecting type bonding method for the large-curvature large-load radar cover and the tension-pressing pad,firm bonding of the tension-pressing pad tested by the large-curvature large-load radar cover is achieved, uniformity and high efficiency of local static test loading of the radar cover are guaranteed, and development of model development is facilitated.

Description

technical field [0001] The invention belongs to the technical field of experimental mechanics, and in particular relates to a full-fill bonding method of a large-curvature and large-load radome tension and pressure pad. Background technique [0002] With the development of aviation technology, in order to adapt to the high-speed flight of the aircraft, the aircraft radomes are no longer designed as the traditional plane without curvature or curved surface with small curvature. The radome bears a sharp rise in load, and it is particularly important to accurately simulate the loading state of the large-curvature and large-load radome, and it is particularly important to carry out the ground static verification test before the aircraft flies. [0003] At the present stage, for the loading of the static test load of the large-curvature and large-load radome, the machine-added symbol-shaped wood block / steel plate combination structure is bonded to the radome to apply the transfer...
