本文以钢制折叠式夹层板为研究对象，对其加载空中爆炸冲击载荷进行结构响应分析。根据夹层板的结构变形解析计算方法，分析得到其在爆炸冲击载荷作用下的结构变形预报公式。同时，利用非线性有限元分析软件Abaqus对相关计算工况进行仿真分析，对结构塑性变形公式进行验证。在此基础上，对夹层板结构尺寸进行参数敏感性分析，研究各参数对夹层板结构尺寸的影响规律，验证解析计算方法预报结果的准确性，为钢质折叠式夹层板的设计和抗冲击性能评估提供参考。
This paper analyzes the structural responses of folded steel sandwich plates under air explosion shock loads. According to the analytical calculation method of the structural deformation, the deformation prediction formula under explosion loads is obtained. At the same time, the nonlinear finite element analysis software ABAQUS is used to simulate the investigated explosive conditions and verify the structural plastic deformation formula. On this basis, the parameter sensitivity analysis of sandwich plate structure size is carried out, and the influence of each parameter on sandwich plate structure size is studied. The applicability of the analytical calculation method for folding sandwich panel is verified, providing a reference for the design and crashworthiness evaluation of steel folding sandwich structures
