specific Embodiment approach 1

[0016] Specific implementation mode one: refer to Figure 1 to Figure 2 This embodiment is described. This embodiment provides a comprehensive test system for the load-bearing performance of an inflatable ring structure, including an inflatable ring 2, a central tensile force loading system 3, a bearing capacity support system 4, and a plurality of support platforms 1; the inflatable ring 2 consists of A plurality of support platforms 1 are supported and fixed, and the bearing capacity boosting system 4 applies bearing capacity to the inflatable ring 2 through the central tensile force loading system 3 to perform in-plane / outer bearing capacity tests, and is controlled by the bearing capacity boosting system 4 The tension sensor 43 displays the applied bearing force value.

specific Embodiment approach 2

[0017] Specific implementation mode two: refer to Figure 3 to Figure 4 Describe this embodiment, this embodiment is to further limit the specific embodiment one, in this embodiment, each of the support platforms 1 includes a stand 19, a pressure sensor 11, a displacement sensor 12, an L-shaped limit rod 13, The inner fixed pulley 15, the inner fixed pulley support plate 16, the outer fixed pulley 17 and the outer fixed pulley support plate 18; the upper end of the platform 19 is provided with a table panel 110 for placing the inflatable ring 2, and the pressure sensor 11 is arranged on the platform. Between the panel 110 and the inflatable ring 2, ensure that the force of the inflatable ring 2 distributed on each stand 19 is the same, and the displacement sensor 12 is placed on the support platform 1 to test the displacement of the inflatable ring 2. After the inflatable ring 2 is inflated After being placed on the stand 19 to determine the position, an L-shaped stop rod 13 i...

specific Embodiment approach 3

[0021] Specific implementation mode three: refer to Figure 1 to Figure 2 Describe this embodiment. This embodiment is to further limit the second specific embodiment. In this embodiment, when carrying out the in-plane bearing capacity test, the L-shaped limit rod 13 is placed on the outside of the inflatable ring 2, and the out-of-plane bearing capacity is tested. During the test, the L-shaped limit rod 13 is placed on the inner side of the inflatable ring 2 . Other compositions and connection methods are the same as those in the second embodiment.

[0022] In this embodiment, according to the size of the inflatable ring 2 to be tested, it can be realized by increasing or decreasing the support platform 1 and various accessories (11-18, 21-22); , the position of the inflatable ring can be limited by adjusting the height of the L-shaped limit rod 13 . .

Abstract

The invention discloses an inflatable ring structure bearing performance comprehensive test system, and belongs to the technical field of inflatable rings. The problem that there is no test device to realize synchronous in-plane and out-of-plane bearing performance tests of inflation ring structures of different sizes at present is solved. The test system comprises an inflatable ring, a central tensile force loading system, a bearing force clamping system and a plurality of supporting platforms; and the inflatable ring is supported and fixed by the plurality of supporting platforms, the bearing capacity clamping system applies a bearing capacity to the inflatable ring through the central tensile force loading system so as to carry out in-plane / out-plane bearing capacity testing, and a tension sensor in the bearing capacity clamping system displays the value of the applied bearing capacity. The system is not limited by the size of the inflatable ring; the limitation by the shape of the inflatable ring is avoided; and the system is not limited by inflatable ring manufacturing materials, and the testing range is wider.

Description

technical field [0001] The invention belongs to the technical field of inflatable rings, and in particular relates to a comprehensive test system for the bearing performance of an inflatable ring structure. Background technique [0002] The inflatable ring is a commonly used load-bearing structure in the inflatable deployment structure. The key to its application is that the inflatable ring structure needs to have a certain load-bearing performance, including in-plane load-bearing performance and out-of-plane load-bearing performance. That is, when the inflatable ring receives the in-plane / out-of-plane load F, its ability to resist deformation, the smaller the deformation of the inflatable ring. It shows that the bearing performance of the inflatable ring is stronger. Test is the most direct method to evaluate the load-carrying performance of inflatable rings, but there is no experimental device that can realize in-plane / out-of-plane load-carrying performance tests for infl...
