Abstract

In this paper, the advanced high-strength steel roll forming technology for automobile crash beams and its applications are studied. Firstly, the importance and research background of automobile crash beams and the advantages of high-strength steel materials in improving the safety performance of automobiles are introduced. Then the key parameters of the roll forming process are discussed in detail, including the elements of roller design, load distribution of the multi-pass roll forming tooling, and roller gap adjustment control. The design of the roll forming process was determined by analyzing the material properties of high-strength steel. Then the simulation and data analysis of the roll forming process were carried out, and the sheet strain in each pass was predicted by finite element simulation, and the mechanical properties and surface quality of the formed parts were evaluated. Finally, the production test of roll forming of high-strength steel for crash beams was carried out, and the crash beams meeting the design requirements were successfully manufactured by accurate roll forming mold processing and high quality mold materials. The dimensional accuracies of the formed parts were examined, and the results showed that the dimensional accuracies of the formed parts were within the permissible range. This study proves the feasibility and superiority of advanced high-strength steel roll forming technology in the manufacture of automotive crash beams.
