Study on the Effect of Altitude on the Height of Three wave Points of Shock Wave

The height of the three-wave point of the shock wave in the blast field will directly affect the damage effect of the ammunition on the target. Accurately obtaining the height of the three-wave point of the shock wave at different altitudes is of great significance for the design of the ammunition and the assessment of the damage power. The paper uses AUTODYN to establish a finite element numerical simulation model of the shock wave pressure distribution of the TNT bare charge explosion field at different altitudes, analyzes the three-wave point heights of the shock wave pressure at the altitudes of 198m, 1500m, 2000m and 4650m, and obtains the effect of the altitude on the shock wave. The influence relationship of the trajectory height of the pressure three-wave point provides a certain degree of guidance for the engineering installation of the free-field shock wave pressure sensor.
