High-speed cold hit test method simulation experiment

The present invention relates to a test method for high speed simulation of cold hit, emitted at the outlet of the test tube method test sample of material by first fixing means provided on the side of the air, and then injected by means of a pneumatic muzzle pressure gas pushing the striking lever in the launch tube strikes the test sample of material, at the same time, the recording of the deformation of a test sample by high-speed video camera and / or infrared camera, since this test method the material under test specimen during clamping, It uses the open clamping manner, so that the deformation of the test sample of material can be recorded a high speed video camera and / or infrared camera down, thereby solving the prior art process of testing the sample of material being tested , deformation of the test sample of material and recording the problem can not be observed.
