Paper Abstract

A dynamic analysis of a flexure support system for a one- meter primary mirror in a space telescope is presented. It is assumed that the primary mirror is held by a three-point flexure support at the back surface. The design study is to be conducted with three different power spectral density functions (PSDF) and four different sized support systems. Mechanical responses of the mirror to each PSDF are to be examined. Using the finite-element analysis program, MSC/NASTRAN, the maximum root-mean-square values of the bending stress and the axial stress in the flexure system due to the launch loads are calculated. As a result, the stiffness and the strength of the flexure in the vertical (optical axis) and tangential directions to accommodate the launch loads are discussed.
