摘　　要：以薄膜温室为研究对象,利用结构力学方法简化温室结构得到分析模型,利用有限元软件ANSYS对其进行仿真。将薄膜和骨架看作一体,薄膜有明显的几何非线性,使温室具有非线性特征。分析结果得到温室在不同载荷下的应力分布和最大位移,为温室整体结构的设计提供了理论依据。Taking the membrane greenhouse as the object of studying, using structure mechanics simplifies it to get the analysis of model and then simulates it by the finite element software ansys. Taking the membrane and struture as the whole, the membrane has obvious geometric nonlinearity, the greenhouse also has it. through simulating, it shows the results of stress distribution and the maximum displacement, when greenhouse is in different loads, which provides a theory to the whole structure of the greenhouse.
