| 摘 要： | 目的为消除爆炸分离冲击信号中的零漂趋势项,提出一种爆炸分离冲击数据处理方法。方法基于分段和线性拟合思想,获取测试数据的零漂趋势项。通过分析原始信号和校正信号的频谱相关性,定量讨论分段窗口数对试验数据有效性的影响规律,进而给出爆炸分离冲击加速度信号的校正原则。结果通过对试验数据进行有效性分析与校正,能够较好地抑制积分零漂,消除基线零漂趋势项对冲击谱的影响。结论该方法可提高试验数据的准确性和有效性。

| Abstract: | Objective To propose a method for pyroshock data processing to reduce the influence of the zero-shift trend in pyroshock signal. Methods Null drift trend items of tested data were obtained based on segmentation linear fitting thought. The influence of the segmentation number on the results of integration and spectrum analysis was discussed by relevance analysis between the original signal and validated one. Then, the correction principles on pyroshock acceleration signal were given. Results Effective analysis and correction on experimental data could restrain the zero-shift trend and reduce the influence of null shift trend on shock spectrum. Conclusion The method can improve accuracy and validation of experimental data. |
