摘　　要：涂层织物类膜材的力学性能具有非线性、非弹性、各向异性等特征,是膜结构设计分析的基础.对Ferrari 1202S2膜材进行一系列单、双轴拉伸试验,并在我国《膜结构技术规程》规定的拉伸试验及德国标准拉伸试验的基础上,采用不同的数据处理方法分别建立双轴线性材料模型及双轴非线性材料模型.建立膜材的本构关系模型,探究精确确定膜材的弹性模量、泊松比等力学参数的方法.The mechanical properties of coated fabric membrane materials are nonlinear, inelastic and anisotropic, which are the basis for the design and analysis of membrane structures. A series of uniaxial and biaxial tensile tests were carried out on Ferrari 1202 S2 materials. On the basis of the China and German fabric specifications, different data processing methods were used to establish biaxial linear material model and biaxial nonlinear material model. The constitutive relation of membrane material was established to explore the method for the determination of elastic modulus, Poisson’s ratio and other mechanical parameters of membrane material more accurately.
