Abstract
A parametric study was performed to optimize the support systems of a large primary mirror. In order to analyze the support pattern locations and the levels of the support forces, finite element models of the primary mirror were employed. Influence matrices for the axial defining supports were established by combining sets of unit load cases which were applied at each of the selected support points in the mirror models. A least square algorithm was utilized to satisfy the design requirements during the optimization process. In this paper, a description of an optimization scheme to define the axial support locations and the force directions of the lateral supports is presented. The optimization procedures were applied to the GEMINI primary mirrors and the optimized force sets were verified by finite element analysis.
