摘　　要：比较了张拉膜和充气膜的异同。基于非线性有限元UL格式,进行充气膜的形态分析和荷载分析,分析中考虑了充气膜的特殊之处。建立了充气膜的优化设计模型,以工程造价为目标函数进行优化。编制了相应程序,算例表明本文的分析方法是可行的。The air-supported membrane structure is compared to the tension one in this paper. On the basis of nonlinear FEM, the shape-form analysis and load analysis are done, in addition, the peculiarity of this kind of structure is considered. The optimize design model of this kind of structure is built, which consider engineering cost as the goal function. The program based on this method is carried out, the example indicates that the program is feasible.

关 键 词：充气膜结构 非线性有限元 优化设计
