To standardize the processing flow of shock wave measurement data in damage experiment, an automatic batch processing method for shock wave measurement data were proposed based on the regional correlation principle of shock wave propagation. The adaptive filter was used in noise processing. The validity test of measurement data was realized by confirming the existence of step waveform in the time range of shock wave arriving at sensor. Mean value method was used to extract shock wave overpressure. Shock wave measurement data processing is efficient and automatic batch processing. The accuracy of data processing is improved.

Explosion Equivalent Quantitative Evaluation of Global Blowup Warhead
TU Guo-yong, WANG Hai-feng, LU Xiao-fei, YANG Hong-bing
Modern Defense Technology    2020, 48 (2): 30-34.   DOI: 10.3969/j.issn.1009-086x.2020.02.005

Explosion equivalent quantitative evaluation of global blowup warhead changes with many factors such as explosive payload and charging type etc. To get some relatively accurate experimental result, concluded and analysed the empirical formula of the shock-wave propagation laws, and built the computational analysis model, which achived the explosion equivalent quantitative evaluation of global blowup warhead.The quatitative evaluation with the model enhances the confidence of the damage experimental result.
