针对冲击波测试中缺乏一致的数据处理正确性判定问题,提出了以峰值数据分布正态性检验作为数据处理正确性的评判方法.在分析常规弹药试验中冲击波超压峰值的规律基础上,利用某型弹药试验结果进行假设检验,验证了数据存在正态分布的客观规律,通过对试验数据采取滤波处理、经验公式拟合处理等方式,分别进行正态检验,与原始数据进行比对,得出了采取不同方法进行数据后期处理的差异,指出了经验公式拟合处理方法的必要性,进而阐明以峰值数据分布正态性检验作为数据处理正确性的评判方法.该方法为提高冲击波测试精度、判断数据正确性提供了参考.
Research on evaluation method of static blast shock wave data processing
To address the lack of consistent determination of data processing correctness in shock wave testing,the normality test of peak data distribution was proposed as a method to judge the correctness of data processing.Based on the analysis of the pattern of peak shock wave overpressure in conventional ammunition tests,a hypothesis test was conducted using the test results of a certain type of ammunition to verify the existence of the objective law of normal data distribution.The method was then used to clarify the normality test of the peak data distribution as a method to judge the correctness of data processing.This method provides a reference for improving the accuracy of shock wave testing and judging the correctness of data.
