포스코 ULSAB 차체 최적설계

Vehicle body stiffness/strength and weight are very important factor for crash safety and driving stability. The global steel industry commitment have developed ULSAB(Ultra Light Steel Automotive Body) to meet these requirements of vehicle. The ULSAB is safe, affordable, fuel efficient and environmentally responsible vehicle. Recently, as the underbody part of ULSAB model has been substituted into hydro forming product by posco, the new ULSAB body with the better performance has been developed. In this study, the light and robust ULSAB model are manufactured by using optimization design based on the sensitivity.
