摘　　要：以帽型加筋板结构为研究对象,设计开展落锤碰撞冲击试验,分析其损伤变形情况。在此基础上,分析确定帽型加筋板结构在碰撞冲击载荷作用下的变形模式,进而推导得到瞬时结构抗力的解析计算公式,并与试验结果比较验证解析计算方法的合理性。该解析方法对帽型加筋板的碰撞性能设计及评估具有指导意义。Hat-profile-stiffened plate is taken as the research object,the drop hammer impact test is carried out to analyze the damage deformation condition of the hat-profile-stiffened plate.On this basis,the deformation mode of hat-profile-stiffened plate structure under collision load is analyzed and determined,and thus the analytical formula of instantaneous structural resistance is derived.The rationality of the analytical calculation method is verified by comparison with the results of model tests.The analytical method established has guiding significance for the design and evaluation of the impact performance of hat-profile-stiffened plate.
