大口径射电望远镜结构的保型设计

发展空间科学,探索宇宙的奥秘,是我国航天科技发展的目标。作为射电天文学主要探测工具的射电望远镜,为适应深空探测的需求,高精度、大口径是其发展的必然方向。大口径射电望远镜结构系统的设计对整个系统设计起着决定性的作用。文中详细阐述了望远镜结构由刚性设计向柔性设计发展的必要性,介绍了望远镜结构保型设计的原理及其在世界知名大型射电望远镜结构设计中的成功应用,并结合我国最大口径的66 m天线的设计实践,证明了该设计方法的科学性与先进性。

Structural Homology Design of Large Diameter Radio Telescope

Developing the space science, exploring the mysteries of the universe, are the goals of China＇s aer- ospace technology. Radio telescope is the main detecting tool of radio astronomy. To meet the need of deep space exploration, high precision and large diameter are the inevitable direction of its development. The struc- tural design of large diameter radio telescope plays a decisive role in the design of the whole system. This pa- per expounds the necessity of telescope structural design developing from rigid to flexible, introduces the principle of homology design of telescope structure and its successful application in the design of notable radio telescope worldwide. Combined with the design practice of China＇s largest diameter （66 meter） antenna, the scientificalness and progressiveness of homology design are proved.
