Abstract

In order to solve the problem of interference in traditional electric measurement of shock wave pressure, a method to evaluate shock wave based on reactant plate plastic deformation is proposed. In case of the theory model is complex and multiple parameters, the dimensional analysis can simplify the progress. With it, the relations of the deformation of reactant plate with TNT equivalent, mounting height and distance of explosion and reactant plate are obtained. Afterwards, the deformation model of reactant plate under standard TNT explosive shock wave is established. Finally, three groups of experiments are designed to measuring the reactant plate deformation in explosion shock wave in three TNT equivalents of 100 Kg, 60 Kg and 20 Kg. And the regression analysis method is applied to calculate the coefficients. Through comparison of the deformation from experiment with the model, the error of vertical reactant plate and horizontal reactant plate is better than 3.59% and 3.33% respectively. Thus this analysis provides new ideals for evaluation of shock wave damage effectiveness assessment and can greatly reduce the amount of explosive experiment.
