两装药同时起爆时金属靶板的动态响应
Dynamic response of a metal target plate to simultaneous initiation of two charges
摘要
Abstract
To study the response law of a metal target plate under the simultaneous initiation of two charges and to construct a calculation model for the deformation and deflection of the target plate under the action of dual explosion source shock waves,the dynamic response of the metal plate under the action of double explosion sources was studied through dimensional analysis.Based on the numerical simulation calculation results using the finite element software,the influence of the charge quality,charge spacing,and vertical distance from the charge to the target plate of the double explosion source on the maximum deflection of the 45 steel target plate was summarized.The results show that the maximum deflection of the target plate increases linearly with the charge mass,decreases linearly with the charge spacing and decreases exponentially with the vertical distance from the charge to the target plate.The functional relationship between different parameters and the maximum deformation deflection of the target plate was fitted.This study can to some extent achieve rapid calculation of the explosion effect of charges with different distributions.关键词
