摘　　要：以整车轻量化为背景,按照高强度钢板热成形的工艺要求,将捷达车原辊压成形的保险杠横梁进行截面和壁厚优化,最后通过静态弯曲数值模拟对设计进行了验证,高强度钢板热成形的保险杠横梁较原普通钢板辊压成形的保险杠横梁更轻且强度更高。On the background of lightweight of vehicle,according to the requirement of hot stamping of high strength steel,the section of surface and thickness of the bumper beam from Jetta is optimized from the original roller forming in this paper.Finally the simulation is performed to verify the design,and the new bumper beam by hot stamping with high strength steel is lighter and stronger than the original part by roller forming with general steel.
