Abstract: Aiming at the problem of the car seat frame quality, the seat frame structure, ergonomics, the topology optimization method, the characteristics and processing methods of magnesium alloys were investigated. According to the actual requirements of the seat and properties and processing of magnesium alloy, the new structural optimization of car seat cushion was established. Finally, a statics analysis of the new seat frame was given. The results indicate that, the quality of the seat frame after optimization is reduced by 20%, and meets the requirements, which show optimization method can be used for structural design of the seat frame. As the same time, a new seat frame is got ten.
