Embodiment Construction
[0024] This embodiment is a test piece clamping device used in an ice wind tunnel environmental test chamber.
[0025] Firstly, the test piece clamping device can be conveniently and firmly installed on the test piece mounting seat of the ice wind tunnel test section; and it must be able to stably clamp the test piece under all test conditions of the ice wind tunnel environmental test chamber requirements; the installation position and installation angle of the test piece can be adjusted according to the actual wind belt width and test requirements of the ice wind tunnel, and the clamping device of the test piece cannot affect the test area; finally, it needs to be combined with the working conditions of the ice wind tunnel environmental test chamber Choose the right material.
[0026] refer to Figure 1 ~ Figure 2 , the present embodiment is used for the test piece clamping device of the ice wind tunnel environmental test box, which is composed of a fixed ear piece 1, a mova...

The invention provides a test piece clamping device for an ice wind tunnel environmental test chamber. The test piece clamping device is fixed on a test piece mounting base of an ice wind tunnel test section, and clamps a test piece stably under all test conditions of the ice wind tunnel test chamber; and the mounting position and the windward angle of the test piece are accurately adjusted according to the actual wind zone width of an ice wind tunnel and test requirements. The test piece clamping device can perform a contrast test on two test pieces simultaneously in a single test, so that the test efficiency is improved. The mounting angle of a test piece mounting arm plate can be adjusted according to different test requirements, wherein a variation range of the angle is 0-180 degrees. Both connection between the test piece mounting arm plate and a mounting plate and connection between the test piece mounting arm plate and the test piece adopt a self-locking bolt, accurate positioning is performed, and looseness between components in the process of an experiment can be prevented at the same time. The test piece clamping device adopts a titanium alloy material, thereby being small in temperature influence, high in rigidity, great in structural damping and good in vibration isolation effect, and being high in corrosion resistance at the same time.
Description
technical field [0001] The invention relates to a clamping device for a test piece, in particular to a clamping device for a test piece used in an ice wind tunnel environment test chamber. Background technique [0002] In the existing technical field, in order to study the anti-icing effect of superhydrophobic materials, researchers usually need to conduct a series of ice wind tunnel tests on superhydrophobic materials. Among them, the main test ice wind tunnel is GS-3000F ice wind tunnel environmental test chamber, which is composed of low-speed return wind tunnel, corner device, refrigeration system, spray system, wind tunnel insulation layer, control instrument It is suitable for simulating icing environments such as aircraft and sensors, and investigating the influence of environmental parameters such as temperature and wind speed on the icing and anti-icing effects of test pieces. GS-3000F Ice Wind Tunnel Environmental Test Chamber, as a low-profile and replacement pro...
