摘要
考虑充气膜结构几何大变形、小应变的主要特点,以非线性有限元知识为基础,进行包括形态、受荷、模态等全过程受力分析。运用分析软件ANSYS8.1,对充气膜结构各不同过程进行非线性有限元分析,以达到最优形态。
Considering the outstanding advantages to the geometrical large distortion and small deformation of air - supported structures and on the basis of non - linear finite element knowledge, the process of formfinding,loading and mode calculation is analyzed. With the analysis software ANSYS, different processes are analysed by the finite element method to find the best optimize shape.
