折叠式网架结构的几何非线性分析

GEOMETRICALLY NONLINEAR FINITE ELEMENT ANALYSIS OF DEPLOYABLE SPACE STRUCTURES

    摘要
  • 摘要: 折叠式网架结构是近年发展起来的结构形式,其主要的应用范围是航空航天工业。因具有很多的优点,其应用范围也逐步扩大到民用建筑之中。在这种结构杆件之间采用了一种特殊的连接方式——枢轴连接,因此单元计算模型也随之发生变化。本文针对折叠式网架结构中出现的特殊单元推导出了几何非线性有限元分析的单元切线刚度矩阵,并对柱壳式折叠网架结构进行了算例分析。

     

    Abstract: Deployable space structure is one of the new types of structures. Its member is a scissor-like element (SLE) which is quite different from conventional grids. In this paper, the geometrically non-linearfinite element analysis is presented with the tangent stiffness matrix derived for a three-node element. Some numerical results for a barrel vault are given.
