摘要
针对五面体单层折板网格结构突出的静力稳定性及其极限承载力问题,运用ANSYS软件中Beam188单元来模拟构件,考虑几何非线性,用特征值屈曲分析和非线性屈曲分析两种分析方式考查了空间折板单层网格的屈曲模态和失稳全过程,得出了一些有意义的结论。
This paper for pentahedron single-layer folded plate grid structure of prominent static stability and the ultimate load capacity, using Beam188 element in ANSYS software to simulate the component, considering geometric nonlinear, buckling analysis and nonlinear buckling analysis of two analysis methods to examine the folding space of single-layer lattice shell buckling modes and buckling process by the characteris- tic value, some meaningful conclusions are drawn.
