Abstract: In order to further enhance the stability of the orbital transportation, the modal characteristics of the orbital support structure were simulated and analyzed. The multi-objective optimization method was applied to design the structure for lightweighting while increasing the first-order natural frequency and reducing the stress peak. Using ANSYS Workbench, the parametric finite element model was established, the length of the intermediate support rod, and the lateral length of the rib were regarded as the parameterized dimensions. Through dynamic characteristic analysis, the natural frequencies, modal shapes, and harmonic response characteristics were obtained. Parametric samples were obtained by using Latin square method, and the approximate model was fitted by polynomial function. Multi-Objective Genetic Algorithm and Sequential Quadratic Programming were applied for optimization calculation. The results indicate that the structurally lightened design can attain higher strength and stiffness.
