| 摘 要： | 采用整体索网作为大射电望远镜(FAST)反射面的支承结构，网格划分形式为短程线型．通过对整体索网的初始预应力态的分析、工作状态的动态模拟以及结构的受荷分析，发现结构的拟合精度均能满足FAST电性能的要求，论证了整体索网结构作为FAST反射面支承结构的可行性．

| Abstract: | The geodesic meshed cable-net structure was used to support the reflector of the Five-hundred-meter Aperture Spherical Telescope (FAST). Based on the analysis of the original prestressed state, the emulation of the working state, and the analysis of its reaction under loads, the cable-net structure proved to be able to meet the functional requirements of FAST, and the feasibility of the cable-net structure supporting the reflector was verified. |
