Abstract

Abstract

Aiming at the shortcoming that the measurement of part points can not acquire the propagation process of shock wave overall and the limitations of the empirical formulae for overpressure, this paper utilizes the weighted generalized inversion to inverse the velocity field of shock wave, acquires the overpressure distribution according to the relationship of peak overpressure and velocity.The inversion results are preferable to the empirical results by experimental confirmation in limitative area.
