Application of sound-vibration coupling analysis in shock wave measurement

In order to high-accurately measure air shock wave, a theoretical frequency response property calculation of the measuring system was presented with sound-vibration coupling analysis. Dynamic response experiments of the measuring system were carried out in a shock tube. The suitable diameters of the damper holes in probes were obtained for three different ranges. Results show that the calculated values of the diameters of damper holes in probes and the jump time of pressure waveform are in basical agreement with the measured ones. The shock pressure waveform measured by the measuring system in intense explosions presents fine frequency response properties.
