Design of steel structure for the dome of ground-based large aperture optical telescope
摘要
Abstract
As the storage and protective enclosure for telescopes,the dome must exhibit superior structur-al performance to ensure safe operation and enable normal observation.With the increasing aperture of ground-based optical telescopes,dome dimensions have correspondingly expanded,presenting challenges to structural stability,environmental adaptability,and operational precision.This study examines the theo-retical positioning and structural design of a dome for large-aperture telescope by comparing and analyzing the configurations and operational characteristics of large dome structures domestically and internationally.Based on the local environmental conditions at the installation site,wind,seismic,snow,and thermal loads were analyzed;combined design loads were then established using appropriate load factors.Load cases for both open and closed states of the dome were modeled using the spatial structure design software 3D3S,and finite element simulations were performed.Results indicate that the maximum stresses in the dome truss system under open and closed conditions are 144.58 MPa and 189.51 MPa,respectively,both below the material yield strength.The calculations and simulations presented provide technical guidance and reference for the design of future large-scale telescope domes.关键词
