The requirements of lightweight design of bumper beam with consideration of crash- worthiness and pedestrian protection were introduced. An aluminum alloy bumper beam for a produc- tion car was designed according to these requirements. With minimizing the mass of beam as the ob- jective, thickness optimization was conducted through central composite design method and adaptive response surface method. Compared with the original beam, the weight of the aluminum beam is re- duced significantly and the performance of crashworthiness and pedestrian protection is enhanced ef- fectively.
