Test method for ground shockwave from the explosive near-field

摘要：

　　In order to accurately obtain the overpressure curve of the ground shock wave from the explosive near-field, the problems existing in the original test method of the ground shock wave are analyzed,and a new test structure is proposed.The principle that the new test structure can effectively suppress the parasitic output of vibration is analyzed.The comparison test between the original test method and the new test method is carried out.After comparing and analyzing the test data, it is found that the new test method can effectively suppress the parasitic effect of vibration and can control the ratio of the parasitic output of shock wave caused by vibration to the peak value of shock wave within 6%.At the same time, it solves the problem that the signal curve increases to the full range value caused by sudden disconnection of the rear circuit of the pressure sensor under vibration or loosening of the signal line connector under vibration suddenly.The accurate measurement of the near-field ground shock wave from the explosive charge is realized.
