Table 1
Data acquisition condition of pyroshock on the open-box-type tension joint.
| | Shock source | CF | Fs (MHz) | Filter (kHz) | Number of samples | CFmr (mm/s/V) | AdB (dB) | Sensing point coordinate |
| | Pyroshock | CF1 = 1.42
CF2 = 1.42
CF3 = 1.42 | 1 | 0.1∼100 | 30,000 | 1,000 | AdB1 = 9
AdB2 = 6
