摘要
在对现有冲击波超压测试方法和特点分析的基础上,为进一步准确测定弹药爆炸时产生的冲击波超压和冲量,提出了一种可行的间接测量冲击波超压的方法,即在求得冲击波速度的基础上,利用兰金--雨贡纽方程(Rankine-Hugoniot)求解冲击波超压,用该试验方法求得的超压值与压力传感器直接测量的超压值进行比对,由此来证明用冲击波速度测试超压这种试验方法的理论可行性。
To measure the shock wave overpressure and the impulse more accurate when the ammunition exploded, a feasible way to measure the shock wave overpressure indirectly was proposed by analyzing the means and features of existing shock wave overpressure measurement. On the foundation of getting the speed, utilized the Rankine- Hugoniot equation to solve the shock wave over pressure, then compared the pressure with which was measured by transducer, to prove the feasibility of this kind of experiment.
