摘要
对一种新型的张拉式索膜结构———倒伞式可展膜结构进行了这种新型结构的特点和它的设计过程,重点研究了它的找形分析过程;对找形原理进行了非线性有限元的理论推导。用ANSYS对一倒伞式膜结构进行了找形分析,对其中的一些重要问题进行了较深入的研究并提出了有实用价值的解决方案,最后得出了主要结论并提出了待解决的问题。
Research is done on a new cable and membrane structure, a developable upssidedown umbrella membrane structureCharacteristics and the design process of the structure is presentedThe formfinding analysis of the developable upsidedown umbrella membrane structure is the main objective of this paperNonlinear finite element formulation of formfinding principle is calculatedFormfinding of a developable upsidedown umbrella membrane structure is realized by ANSYS research is conducted on some important related problems and feasible solutions are given accordinglyAt the end of this paper,major conclusions are got and problems to be solved are put forward
