The theory of the simulation is that, firstly put fuze and parts in simulation device in reverse, then fire them in high speed by air gun , and they fly into gun spinning quickly and impact cushion and brass block in it , negative acceleration because of impact is to simulate setback , meanwhile they spin with spin gun when impacting, so spin environment can be simulated, so the simulation system can stimulate setback and spin of fuze in fire.

该模拟系统的原理是将引信及其零部件倒置在模拟弹丸中,通过空气炮以高速发射出去,然后飞入高速旋转的旋转管内,与旋转管内的缓冲块和黄铜块碰撞,碰撞而形成的负加速度作为引信发射时受到的后坐,由于碰撞时与旋转管一起旋转,模拟引信发射时的旋转环境,达到模拟引信发射后坐与旋转环境的目的。
