Abstract: In order to solve the problem that the position of the airborne dynamic explosion is difficult to measure, a five-zone positioning method based on the results of the shock wave overpressure test was studied. The digital pressure recorder was composed of a test square in the explosion area, and all the measuring points were divided into five zones according to the estimated distance from the estimated point of the heart. Multiple sets of measuring points were obtained by selecting one measuring point in each zone, and the relative coordinates of each set of measuring points and the shock wave overpressure value were taken as raw data. The functional equations were established based on the airborne static explosion free-field shock wave propagation law, the dynamic explosion shock wave overpressure engineering calculation formula, and the wall reflection law. The Matlab software and the Levin-Marquard method were used to iteratively get a set of core coordinates, and the Gurbus method was used to eliminate the anomaly data and calculate the average of the remaining data to obtain the final three-dimensional coordinates of the core. Combined with the actual explosion test, the calculation results were compared with the monitoring results. The results show that the method is reliable and effective for obtaining core coordinates.
