摘要
传统的钢质车架不符合轻量化,而全铝合金车架强度难以满足商用车的要求且制造和维修成本较高。钢铝结合车架利用铝合金替代部分钢制零件,充分发挥铝合金在轻量化方面的优势,借助结构优化设计,在保证强度的同时,既节省成本,又达到了轻量化的目的。综述了钢铝结合的商用车车架轻量化技术研究现状,总结了钢铝材料在车架上的国内外应用现状、目前所面临的关键问题、钢铝车架CAE优化方法及钢铝材料连接工艺,最后作出了总结和展望。
The traditional steel frame does not meet the requirements of lightweight,while the strength of all-aluminium alloy frame is difficult to meet the requirements of commercial vehicles and the cost of manufacture and maintenance is high.The steel-aluminium combined frame uses aluminium alloy to replace some steel parts,and gives full play to the advantages of aluminium alloy in lightweight.With the help of structural optimization design,it can not only ensure strength,but also save cost and achieve the goal of lightweight.This paper summarizes the research status of lightweight technology of steel-aluminium bonded commercial vehicle frame,summarizes the application status of steel-aluminium materials in the frame at home and abroad,the key problems faced by steel-aluminium bonded frame,the optimization method of steel-aluminium frame CAE and the connecting technology of steel and aluminium,and finally makes a summary and prospect.
