摘　　要：本研究通过建立气动冲击响应谱试验系统,实现了高量级冲击环境模拟,并借助高速摄影及图像分析测速技术,研究了气室压力、弹头速度、弹头质量与冲击谱型间的相互关系。结果表明,该系统可以较好的实现高量级冲击环境模拟;此外,研究表明,冲击气压可明显改变弹头冲击速度,进而改变冲击量级;同时,在一定气压下,不同质量的弹头会改变冲击谱型斜率。In this work, a pneumatic shock response spectrum test system was established to simulate a high level shock environment, and the interrelationship between air chamber pressure, bullet velocity,bullet mass and shock response spectrum was investigated with the high-speed photography technique and image analysis technique. The results show that the system is able to simulate the shock environment at a high level, and that the air pressure can significantly change the shock velocity of the bullet,thus altering the shock level. In addition, under a certain air pressure, different masses of bullets will change the slope of the shock response spectrum.
