中文摘要：
对四边固定带预制孔靶板在爆炸冲击波载荷作用下的动态响应问题进行了实验研究.通过设计爆炸冲击波载荷对2种材料不同孔数、不同孔径的靶板的冲击工况,获得了各靶板的中心点挠度.通过分析,得到了预制孔靶板中心点挠度与预制孔数、孔径的相关规律,结合无孔平板在爆炸冲击波载荷下的挠度公式,建立了广义的靶板中心点挠度公式,可用于计算不同孔靶板的中心点挠度.研究结果可作为平板材料在破片冲击波联合毁伤研究的基础,为杀爆战斗部威力评估提供一些依据.
英文摘要：
To explore the deformation features of the plates with holes under blast waves,thin plates of two materials were prepared by adopting three kinds of hole numbers and three kinds of hole diameters to gain the rules of deflection at the centre of the plates.A generalized deflection formula was proposed by combining the existent deflection formula for the plates without holes subjected to blast loading.The proposed deflection formula can be used to calculate the deflection at the centre of the plates with holes.
