To address the limitations of existing optimization methods that focus on single objectives or neglect stiffener features, a multi-objective topology (MOTO) method is proposed based size and layout. By constraining initial structural performance parameters, optimal height determined through optimization. Based height, single-objective used to achieve best material distribution. The width treated as design variable, while MOTO performed load point displacement, first natural frequency, mass, thereby yielding an performance. Finally, multi-dimensional analysis width, dynamic static characteristics stiffened thin-plate structure conducted. results indicate optimized layout considerably improved. Compared structure, maximum average displacements are reduced by 23.26% 8.62%, respectively. frequency increases 3.81%, resonance amplitude overall mass decrease 39.97% 1.99%, achieves lightweight maintaining better stiffness low-frequency vibration resistance. feasibility effectiveness validated.
