摘要
为获取轻气炮冲击实验有效的观测方法,设计了一种用于一级轻气炮的高速摄影系统,给出了摄影系统的布置、安全防护和光路设计.利用该实验系统研究了弹丸垂直冲击靶体和斜冲击靶体情况下,弹丸碰靶前的飞行姿态、碰靶后的侵彻过程以及混凝土靶体飞溅物的运动状态等,结果表明高速摄影方法在轻气炮进行冲击过程中能够捕捉到弹丸在整个冲击过程中速度和姿态的连续变化情况以及靶体破坏状态等大量信息.
To study effectual observation way of impact experiment with the light-gas gun,a high-speed photography system applied to light-gas gun was designed.The setup of photography system,safety protect and optical design were given.Aiming at the conditions of projectile impacting target vertically and obliquely,the flight attitude of projectile before impacting target,the penetration process after impacting target and the motion state of pieces of concrete target were studied by the experiment.The result shows that the variations of velocity and attitude of projectile in the whole impact process and the damage state of target can be caught by high-speed photography in the impact process of light-gas gun.
