- Abstract:
- To study on the performance consistence of the large-caliber telescope, the main 1m-caliber telescope was structure-designed and analyzed to achieve the comprehensive result. The materials of the main telescope were selected by comparing the materials’ nature, and light-weight design was proformed. After choosing the supporting scenarios of the main telescope and prepare case models. We proceed modal analysis to the main telescope parts, and verified supporting materials. Last, we conducted the gravity-transformative and thermal analysis on the main telescope. The weight of the main telescope was reduced to 76kg with a light-weight ratio of 77%. The simulation results indicated that: the RMS of axial and radial direction of the speculum were 8.9 nm and 3.5 nm respectively. After performing optimal design viai Sight, the radial self-weight deformation RMS of the primary mirror was improved to 3.3nm, decreased 5.7% comparingwith the RMS before optimization. When the temperature of main specular body reached 20± 0.3℃, the RMS was 10.1 nm, which satisfied the surface figure accuracy of the telescope.
