【摘要】 考虑充气膜结构的几何大变形和小应变的特点,以建筑力学和造型技术为基础,对不同造型充气结构的约束条件、力学性能等方面进行分析,总结不同造型充气结构的优缺点并对其进行造型分类,突出其不同功用。最后,通过对逐步充气加压过程中,充气造型的几何变化特征和膜面应力变化进行分析,总结不同造型在不同边界、不同内压下的变化规律。更多还原

【Abstract】 Considering advantages of large geometric deformation and small distortion of air-supported membrane structure,constrain conditions and mechanics characteristics to the different air-supported membrane structures are analyzed based on the construction mechanics and modeling technology.The advantages and classifications for different membrane structures are summarized.At last,through analyzing the features of geometric deformation of model and the stress in the membrane surface,the rules under different boundary conditions and different inner-pressures are summarized.更多还原
