介绍了一种在气炮上研究材料冲击压缩特性的反向冲击法,即将待测试样装在弹头上,用电磁粒子速度计测量有机玻璃靶中的波后粒子速度,依据阻抗匹配原理来换算待测材料的动力学状态量。该方法对研究岩石类等特殊材料(如非均匀材料、铁磁材料、导电材料、昂贵材料、难加工材料)的冲击压缩特性是非常有益的。 A reverse impact method was introduced to study the impact compression characteristics of gas material on gas cannon, that is to say, the sample to be tested was mounted on the projectile and the particle velocity in the plexiglass target was measured by using the electromagnetic particle velocity meter. According to the principle of impedance matching Convert the amount of kinetic state of the material under test. This method is very useful for studying the impact compression characteristics of special materials such as rocks and so on (such as non-uniform materials, ferromagnetic materials, conductive materials, expensive materials and difficult-to-process materials).
