Embodiment 1

[0054] (1) The following process is the transfer process of the wind tunnel test section from the working station inside the wind tunnel to the parking station outside the wind tunnel. At this time, the wind tunnel test section has been disconnected from other sections, and the relevant pipelines have also been disconnected .

[0055] Its operation steps are as follows.

[0056] a. According to the weight of the wind tunnel test section, select the number of vehicles in parallel (that is, the number of transport vehicles), and the remote control transport vehicle drives under the wind tunnel test section at the working station in the wind tunnel.

[0057] b. The height adjustment unit of the remote control transport vehicle rises, so that the V-flat guide rail used for positioning and loading is separated from the wind tunnel test section.

[0058] c. The transport vehicle and the wind tunnel test section leave the working station in the wind tunnel together and move to th...

Abstract

The invention discloses a large wind tunnel test section replacement method. The purpose is to solve the problem that according to an existing wind tunnel test section transportation mode, travellingmechanisms turn inconveniently or positioning is not accurate during replacement. According to the large wind tunnel test section replacement method, test section transportation vehicles are adopted for conducting test section transportation and replacement, a test section is not provided with travelling mechanisms, and through lifting, 90-degree turning of wheels and freely parallel operation ofthe multiple vehicles of the test section transportation vehicles, turning of the wind tunnel test section is achieved; meanwhile, a V-flat slideway mode is adopted for positioning wind tunnel test stations of the test section, round liquid hydrostatic bearings are arranged on the test section transportation vehicles and are used for reducing transverse friction force when the test section falls into a slideway, and through cooperation of the V-flat slideway, the wind tunnel test section and the round liquid hydrostatic bearings, the wind tunnel test section is precisely positioned. By means of the large wind tunnel test section replacement method, the problems that during wind tunnel test section transportation and replacement, positioning is not accurate, and the travelling mechanisms need to turn can be effectively solved, so that the large wind tunnel test section replacement method has a high application value.

Description

technical field [0001] The invention relates to the field of aerospace wind tunnel tests, in particular to a method for replacing a test section of a wind tunnel, which is a method for replacing a test section of a large wind tunnel. Background technique [0002] Typically, a wind tunnel will have several test sections for different purposes. Depending on the purpose of the test, it is usually necessary to use different test sections. The test section is usually transported in the following ways: [0003] (1) Transport by rail transport vehicle [0004] The test section has its own walking mechanism, which, together with the rail-type transport vehicle, realizes the transportation and replacement of the test section, and uses positioning pins for positioning; [0005] (2) Air cushion transportation [0006] An air cushion is set under the test section. After the air cushion is inflated, the floating height of the air cushion is adjusted so that the test section is in a s...
