Abstract
This paper addresses the design of a rib-stiffened shell antenna with the adaptive structure system by simultaneous optimization of the structure and the actuators to improve the surface accuracy of the space antenna. A rib-stiffened shell antenna is proposed for the antenna structure concept with the adaptive structure system. The simultaneous design optimization is performed for the 1/6 element model of rib-stiffened shell antenna. The results of the design optimization show that the higher precision surface can be obtained by the simultaneous optimum design than the individual optimum design. The feasibility of the simultaneous optimum design is examined experimentally. The surface error obtained by the experiment is in agreement with the surface error of the design optimization, and thus, the feasibility of the simultaneous optimum design is verified.
