摘要
侧撞性能是现代汽车安全性能重要的一部分,侧门防撞杆是车辆侧门重要的结构零件,在侧门受到侧撞冲击时,侧门防撞杆承受和吸收大量的冲击能量。研究优化了目前较为广泛的应用,即几字梁侧门防撞杆的断面,对断面拉伸梁的吸能性能进行正交优化分析,得到高效的防撞杆断面。
Side crush performance is an important part of modern vehicle safety performance. Side impact bar is an important structural part of side door. When the side door is impacted by side impact, the impact bar can bear and absorb a large amount of impact energy. The cross-section of the 'n-shaped' impact bar, which is widely used and has excellent performance, was studied and optimized. The energy absorption performance of the cross-section-extruded beam was analyzed by orthogonal optimization method, and the cross-section of the side impact bar with high efficiency was obtained.
