Abstract
High-strength and lightweight methods for vehicle parts include methods such as optimization and application of lightweight materials by reflecting load or material characteristics. Safety regulations have been established in accordance with the loads affecting the vehicle to secure the safety of the vehicle. In order to reduce the weight, high strength materials such as high strength steel (HSS) or high tensile strength steel (AHSS) have been studied. In addition, research on additional lightweight optimization is actively performed by removing parts that do not require high strength or replacing them with plastics. The process of designing a vehicle or part with different properties and considering various loads is costly and time consuming. In order to secure safety and light weight, the authors propose an approximate model for the optimal design of the seat frame that has a direct impact on occupants among the parts of the vehicle, and reduces the development cost, time, and intuitive design through the procedure.
