doi:10.3969/j.issn.1000-1093.2016.08.013

Abstract

Abstract: An effect target evaluation method is proposed to evaluate the near-field underwater explosion power of charges, which considers the power evaluation and the structural damage. The calculation method of target deformation is established and validated through the experiment and theoretical study of slip boundary circular plate, and the distribution characteristics of energy in near-field explosion are obtained. The equivalent relation among different scale target plates is established by the dimensionless power damage factor. Based on these studies, the test equipment and method for evaluating near-field underwater explosion power are preliminarily established. The results show that, for the near-field underwater explosion, the deformation energy ratio firstly decreases rapidly and then tends to be gentle as the distance increases. In comparison to conventional evaluation method, the effect target evaluation method is able to represent the damage power of charges in near-field underwater explosion.
