摘要
针对传统的爆炸冲击波拟合方式,提出了一种利用小波分析对数值拟合的结果进行高频修正的方法,并对修正前后与实测值的相似性和幅值变化进行了比较,实验结果表明这种方法能更加准确地表示冲击波信号,体现出实验中的特殊性和偶然性。
In view of traditional explosive shock wave fitting way, proposed one kind of method which the value fitting result using wavelet analysis carried on the high frequency revision and the fore-and-aft revision has been carried on the comparison with the actual value similarity and the peak-to-peak value change. The experimental result indicates this method be able to express shock-wave signal more exactly and embody in the experiment the particularity and fortuitousness.
