In order to study the protective performance of minesweeper protective equipment on the chest and abdomen under the action of explosion shock wave,it is necessary to explore efficient test methods to improve the experimental research index system and overall performance of individual soldier protective equipment.In this paper,two sets of minesweeper protective equipment were taken as experimental research objects,and the real explosion test of minesweeper EOD operators for typical kneeling posture was designed based on Hybird III dummy model under different sealing conditions.The shock wave was generated by the explosion of 50 g TNT charge column.Two wall overpressure sensors were installed in the chest and abdomen of the dummy model to measure the shock wave overpressure generated by four real explosion tests,and a free field pressure sensor was set at the same distance relative to the explosion source to compare the test data.Using the dummy data acquisition system,the whole process data of overpressure on the chest and abdomen after the shock wave penetration of the minesweeper protective equipment were obtained.Through data processing,the pressure-time curve of chest and abdomen subjected to explosion impact and the peak attenuation rate of overpressure were obtained and compared.The test results preliminarily verify that the better the sealing performance of the joint,the higher the protection performance,which indicates that the protective equipment with high sealing performance has a certain blocking attenuation effect on the diffraction of explosion shock wave,and can reduce the damage caused by superimposed overpressure to the chest and abdomen to a certain extent.The experimental design and data analysis in this paper can be used for further equipment performance improvement.
