中文摘要：
为了考察铝蜂窝夹芯板在爆炸载荷下的动态响应，采用自行设计的冲击摆系统，用激光位移传感器测定了爆炸载荷作用在铝蜂窝夹芯板上的冲量，对夹芯板的变形和失效模式进行了归类和分析，并就芯层的几何尺寸、炸药当量及板厚对其响应的影响进行了系统研究。给出的理论分析结果与实验结果吻合较好。
英文摘要：
A large number of experiments were conducted, and the experimental results were reported and discussed. The quantitative results were obtained based on the measurement in the tests by a ballistic pendulum with corresponding sensors, and then the deformation/failure modes of specimens were classified and analyzed systematically. According to the experimental results, a parametric study was carried out, in which the effect of face-sheet and core configurations, such as face-sheet thickness, cell size and foil thickness of the honeycomb, and mass of charge, on the structural response were investigated. Good agreement between the experimental results and theoretical analysis indicates that the proposed method is a powerful approximation method for the dynamic plasticity analysis of a sandwich structure.
