Experimental study on shock wave from dynamic explosion of a warhead based on seismic wave triggering

A method for measuring the shock wave overpressure of blasting warhead explosion based on seismic wave triggering was proposed. By the proposed method, the peak overpressure of the blast wave from dynamic explosion of a warhead can be obtained reliably. The air explosion shock waves of the blasting warhead with the target velocities of 0, 535 and 980 m/s were measured, respectively. And the measured results of the peak overpressure of the shock wave from dynamic explosion of the blasting warhead were compared with those by the empirical formula calculation. The influence of warhead velocity on the pressure field distribution of the shock wave was analyzed quantitatively. Finally, a three-dimensional visualization model for shock wave overpressure from dynamic explosion of the warhead was reconstructed by using the thin-plate-spline interpolation method. The reconstructed model can provide a basis for studying the characteristics of dynamic explosion shock wave based on the measured data in the complex environment of an actual combat.
