| 摘 要： | 对新型空间结构——折叠网架的计算模型进行了详细地分析与探讨．此种结构的基本组成单元为剪式铰，利用有限元中的主从节点技术将这种特殊的三节点梁式杆单元转化为通用的两节点梁单元，从而为能用通用的结构分析程序来计算分析折叠结构开辟了一条新径，最后对折叠网架模型进行了试验分析．从结果中可以看出，理论值与试验值吻合很好．

| Abstract: | The computing model of deployable structure has been analysed in this paper.The basic element in this structure is the scissors.The method of main follow node in the finite element has been used to transfer the special 3 node element into 2 node beam element which can make it possible to design this structure in ordinary programme for structure analysis.At last a test of the deployable model has been done and the test results are in good agreement with theoreticol values. |
