• Bumper beam is one of the key structural parts,which plays an important role in the frontal crashes of automobile. With the global trend of light-weighted automotive parts,the light weight of bumper beam at-tracts extensive attention of automobile manufacturers,and hot stamping technology with significant weight ad-vantage has become one of the main light weight measures for bumper beam. The quasi-static press,low speed crash and frontal crash simulation models of bumper beam were established according to its actual working con-ditions in the automobile crashes. The feasibility of replacing normal steel bumper beam with hot stamping bum-per beam was analyzed. Meanwhile,the stiffeners in the front face of hot stamping bumper beam were opti-mized with topography optimization in order to further improve its performances.
