자동차용 경량 시트의 안전도를 고려한 최적화 설계 및 해석

The purpose of this study is to suggest a concept of automotive seat design to reduce the structural weight and to develop the seat frame strength. In the paper, structural analysis required for development of seat frame was accomplished according to the test requirements by FMVSS 202. Using optimum design, upper and lower bracket detected as stress concentrated points were reinforced to reduce the maximum stress value. The most effective way to reduce the weight of seat frame is to use lighter materials like aluminum. The weight of aluminum seat frame could be reduced to about 43% compared with the existing steel seat frame.
