摘　　要：为了使加载破片达到弹药安全性试验所要求的初速,文中采用火药驱动破片的内弹道参数进行仿真计算,设计了一种大药室、小口径的高速破片加载装置来提高破片速度,利用气动分离的破片弹对其加载性能进行试验验证。研究结果表明:该装置可以将18.6 g标准破片加速到1 830 m·s±60 m·s范围内,且破片速度稳定,能满足目前国内开展弹药安全性破片撞击的相关试验需要。The internal ballistic parameters of propellant-driven fragments were simulated and calculated, and a high-speed fragment launcher with large chamber and small aperture was designed to improve the fragment speed.Its performance was verified by using pneumatic separated fragment projectiles. The results show that the device can accelerate an 18 g standard fragment to 1 830 m·s± 60 m·swith a stable velocity.The device can meet the needs of fragment impact tests of ammunition safety in China.
