Embodiment Construction
[0016] The utility model is described in detail below in conjunction with specific embodiments.
[0017] Such as figure 1 , figure 2 As shown, the gas cannon device for testing the dynamic performance of the material includes the combination 1 of the projectile and the flyer, and the combined test piece 2. The combination 1 of the projectile and the flyer and the combined test piece 2 are separated. The combination 1 of bullet and flying piece comprises projectile body 3 and flying piece 4, and projectile body 3 and flying piece 4 are cylinders respectively, and the front end of projectile body 3 is provided with flying piece seat, and this flying piece seat is formed by the front end surface of projectile body 3. The middle part is inwardly recessed to form, and the size of the flying sheet seat matches the size of the flying sheet 4, and the flying sheet 4 is placed in the flying sheet seat, and the flying sheet 4 is closely matched with the side wall of the flying sheet s...

The invention discloses a gas-gun device for testing material dynamic property, which is characterized by comprising a combination of a bullet and a flying plate, a combined test piece; wherein the combination of the bullet and the flying plate and the combined test piece are separated from each other; the combination of the bullet and the flying plate comprise a bullet body and a flying plate which are both cylinders; the front end of the bullet body is provided with a flying plate seat which is formed in the way that the middle part of the front end of the bullet body recesses inwards; the flying plate is arranged in a flying plate seat, the size of which is matched with the size of the flying plate; the flying plate is tightly matched with the lateral wall of the flying plate seat; the combined seat is provided with at least 3 stairs in sequence in the same direction, each stair is respectively provided with a probe point; the combined test piece and the flying plate are made from the same material. Proven by experiments after being applied, the device has very high precision compared with standard material parameter, thus serving as the device for testing material dynamic property.
Description
technical field [0001] The utility model relates to a gas cannon device for testing the dynamic performance of materials, which belongs to the field of material testing devices. Background technique [0002] In recent years, domestic and foreign researches on high-strength concrete and high-strength steel fiber reinforced concrete have been carried out to test the resistance to penetration and explosion of conventional weapons. The material state equation is mainly obtained through experiments, and the experiments in this area are not enough. The gas cannon is the impact loading device used in the current experiment. The gas cannon can launch projectiles at high speed and collide with the test material for loading. In the 1990s, Grady and others began to use gas cannons to obtain Hugoniot data under shock compression, Yan Shaohua (Experimental research on high-pressure state equations of high-strength concrete and steel fiber high-strength concrete, Journal of PLA Universit...
