Design Requirements

Abstract Design requirements for a support truss used in a segmented reflector telescope test-bed are identified. From these requirements a baseline model of the support truss is developed. Multicriteria optimization and Pareto optimality concepts are employed to obtain an optimal truss structure among variations of the baseline model that yields a correct balance between strength and flexibility. Modal analysis shows that the structure exhibits the characteristics of a large space-borne structure.
