爆炸分离冲击环境测量中滤波频率影响研究

摘要

概述了航天器的爆炸冲击环境特点,介绍了爆炸冲击环境测量过程中存在的问题,阐明了测量系统各环节采取低通滤波器的必要性.以实测数据为例,研究了不同低通滤波截止频率对数据分析结果的影响,并针对性地提出了爆炸分离冲击测量中滤波器频率的设置建议.%Characteristics of pyroshock environment on space rocket are given in this paper. Some problems on measurement of pyroshock environment and the necessity of low pass filters in measurement system are also described here. Finally, an example is provided to illuminate the influence of different low pass filter cutoff frequency on the data analysis results.
