摘要
基于数值模拟,研究了焊接边宽度及新型焊接边设计对双帽形薄壁梁吸能特性的影响。动态落锤试验结果证明,宽度的增加和新型焊接边设计均可有效提高平均压溃力与比吸能。
Spot- weld double- hat section is the main structural form selection of automobile and ship safety collision. The effects of width and new shape of spot- weld on thin- walled beam energy absorption characteristics were investigated through the simulation analysis. Results of drop hammer experiment show that the crushing force and SEA can be significantly increased by the width increasing and new shape of spot- weld.
