| Abstract: | In view of the wide loading range of the metro vehicle seat model and the seat support structure symmetry features, the topology optimization of the metro vehicle seat support is carried out. The mathematical model of topology optimization is built by SIMP theory. The substructure method and the mode repetition are presented to optimize the structure, which meets the requirements of the design. The comparison results show that the mass of the optimized metro vehicle seat support is reduced by 49%, and the whole strength of the metro vehicle is enhanced, which can meet the lightweight target of the metro vehicle seat bracket. |

| Keywords: | topology optimization substructure method mode repetition metro vehicle seat support flexibility |
