摘　　要：为实现二级轻气炮发射长杆弹的弹托分离、充分发挥二级轻气炮的发射性能,提出了一种机械式脱壳系统设计。在二级轻气炮上应用该技术进行了脱壳试验,利用AUTODYN软件对该系统的工作过程进行了数值模拟,通过与试验结果比较,证明了数值模拟的准确性,最后通过数值模拟对不同速度条件下脱壳系统的工作性能进行了研究。结果表明:该脱壳技系统设计合理,在500～1 750 m/s速度范围内,均可实现对长杆弹的弹托分离,且效果理想;当发射速度低于1 500 m/s时,脱壳器损伤较小,可重复使用。In order to launch long-rod projectiles with a two-stage light-gas gun,a mechanical shelling system was designed to realize shelling of long-rod projectiles and give a full play to the firing performance of the two-stage light-gas gun.This system was used to conduct shelling tests on the two-stage light-gas gun,and the working progress of this system was simulated with the software AUTODYN.The numerical simulation results were compared with those of tests to verify the correctness of the former.Finally,the system working performance was studied under conditions of different velocities using numerical simulation.The results showed that this shelling system’s design is reasonable,and its effect is ideal within the launch velocity range of 500-1 750 m/s;when the launch velocity is less than 1 500 m/s,the shelling system has a smaller damage and can be reused.
