摘　　要：碳纤维横臂和车身、轮边的粘接工艺会极大地影响悬架的强度,这是许多方程式车队在悬架轻量化道路上需要攻克的一大技术难点。为此,基于中国大学生方程式汽车大赛(Formula Student China,FSC)对悬架整体进行受力分析,并对粘接工艺、材料选取等方面进行研究,利用ANSYS进行动力学仿真,控制粘接面的粗糙度和连接同心度等,最后进行多次拉伸试验,设计一套受力最高可达36 kN的基于美国3M DP460结构环氧树脂胶和铝合金接头的碳纤维悬架粘接方案,完全满足赛车需求,保证车手在赛车练习和比赛时的安全,确保悬架性能的正常发挥。The bonding process of carbon fiber crossarm,body and wheel edge will greatly affect the strength of the suspension,which is a major technical difficulty that many formula teams need to overcome on the road of lightweight suspension.Therefore,based on the Formula Student China(FSC)competition,the force analysis of the whole suspension was carried out,and the bonding process and material selection were studied.Dynamic simulation was carried out using ANSYS to control the roughness of the bonding surface and the connection concentricity.Finally,multiple tensile tests were carried out.A set of carbon fiber suspension bonding scheme based on 3M DP460 structure epoxy resin adhesive and aluminum alloy joint with a force up to 36 kN is designed,which can fully meet the needs of racing cars,ensure the safety of drivers during racing practice and competition,and ensure the normal performance of suspension.
