Paper Abstract

For a large aperture astronomical telescope, it is difficult to get the best performance design because there are so many design parameters need to be optimized. In the past, the optimization was carried out for each design parameter individually and the cross impact of different design parameters was neglected. To solve this problem, integrated optimum design was adopted to identify the interaction between parameters and to obtain an approximate explicit function by fitting those calculated design points, so the best design point can be determined. In this paper, an integrated optimum model was established to quest the optimized design of a honeycomb mirror. The individual and interactive impact of design parameters to the mirror’s surface error were analyzed based on this model. Through the optimized integrated design, the weight of mirror had been declined from 109.1 Kg to 74.1 Kg with a little increase of the mirror surface error.
