Abstract：Using a mass-spring equivalent model, the structural optimization problem of a large flexible solar array wing was studied in this paper. A method called “Design of Experiment” was used to build a numerical surrogate model of a solar array wing. The sensitivity and the main effect of the first frequency on key parameters were analyzed. According to the numerical surrogate model of the solar array wing, both MIGA global optimization algorithm and the NLPQL gradient algorithm can increase the first frequencies under the restrained condition of reducing overall mass. The result shows that this method can optimize the structure design and contribute to determine the structure scheme effectively, which has paid an important part on successful development of the solar array of China Space Station.
