基于Grubbs准则的冲击波超压异常值处理方法

Shock Overpressure Outlier Processing Based on Grubbs Criteria

针对弹药威力评定冲击波超压测试中出现异常值问题,采用了基于Grubbs准则测试异常值处理方法,并将数据处理结果与3σ法则处理结果进行了比较,Grubbs准则更适用于样本数量少的情况,更能有效判定异常值并予以剔除。

Aiming at the problem of abnormal values in shockwave overpressure testing,a method of data processing based on the Grubbs criterion was presented. The lethality assessment results of comparing the method with 3σ rule show that the data processing method based on the Grubbs criterion is more effective to judge and eliminate the abnormal test value in the small sample test. The method of data processing can offer an important reference for ammunition shockwave overpressure testing.
