超高速弹撞击岩石的地冲击效应理论与实验研究

The hypervelocity kinetic energy weapon is a new type of strategic strike weapon, which will produce serious impact effect on the ground. In this project, it is investigated that the similarity theory of ground shock on granites impacted by hypervelocity projectiles. Firstly, the relationship between the ground shock and the characteristic parameters is clarified. And the energy distribution and similarity law of the ground shock by the hypervelocity projectile are revealed by means of the fine measurement on the ground shock propagation in target. Then the equivalent calculation method of ground shock induced by hypervelocity projectile is constructed to provide a theoretical basis for protecting against hypervelocity weapons on the ground.
