摘　　要：阐述量纲分析和相似理论的重要意义和工程应用价值,针对具有双层结构材料的轴对称柱形壳体,运用量纲分析的方法,依据模型和原型基本相似特点,开展其在脉冲载荷加载下动力学响应分析,建立在特定条件下无量纲因变量与无量纲自变量间的函数关系,开展缩比模型样件验证试验,试验结果证明了理论推导的正确性。The significance of dimension analysis and its engineering application is described.For double axis symmetry structure shell the dynamic response of the shell has been studied based on dimension analysis and the relation of non-dimension between independent variables and dependent variable for the shell is obtained.Its correction has been verificated by experiment and it will be an important method for study the dynamic response of large size structure in engineering.

关 键 词：量纲分析 动态响应 试验验证
