Abstract

The structure and material of automotive B-pillar have a significant impact on side collision safety. Through collision simulation analysis and orthogonal experimental design methods, a comparative analysis was conducted on the upper and lower materials of the B-pillar outer panel, as well as the boundary line. The intrusion amount and intrusion velocity were used as evaluation criteria to find a better match for protecting passengers inside the vehicle. The research results showed that after optimization, the maximum intrusion amount of the B-pillar outer panel is reduced by 14.7%, and the maximum intrusion velocity is reduced by 7.4%, which can effectively reduce the impact and compression injuries to passengers inside the vehicle.
