燃料空气炸药爆炸压力场测试系统误差分析

Testing System Deviation Analysis of Blasting Pressure Field of Fuel Air Explosive

结合燃料空气炸药武器野外爆炸试验的实际情况．运用误差理论．分析了自由场冲击波压力测试系统的误差传递规律。得到了冲击波超压的相对误差计算式。研究表明：用算术平均偏差估算ＦＡＥ武器爆炸状态场冲击波侧向超压的测量误差比用标准差更切合实际。

In order to measure precisely the pressure field parameters of the FAE weapon blasting state field and to make out its distribution law. this paper. basing on the deviation theory and the actual FAE weapon fleld explosion experience, analyses the deviations transfer law of the free fleld shock wave pressure testing sys- tem and finally obtains the shock wave relative deviation formula. The research reveals that the method of arith- metic average deviations is used to figure out the shock wave incidence overpressure testing deviation of the FAE weapons blasting state field is more practical than that of standard deviation. In addition, this paper also suggests the technical measures to raise the measurement precision of the free field shock wave pressure field pa- rameters.
