摘　　要：通过材料的性能评价及产品CAE分析,采用缠绕法成型工艺完成碳纤维复合材料轴管的成型,铆粘连接技术实现轴管与金属万向节的可靠连接,开发的碳纤维复合材料传动轴将原有的两段串联合并为一段,取消了一对金属万向节,质量降低超过40%。台架试验结果显示,产品静扭强度、扭转疲劳寿命、临界转速等各项性能指标均满足国家汽车行业标准QC/T 29082—2019《汽车传动轴总成技术条件及台架试验方法》的要求。Through material performance evaluation and CAE analysis,carbon fiber composite shaft tube is crafted using winding molding process,the adhesion riveting technology realizes the reliable connection between the shaft tube and the metal universal joint.The developed carbon fiber composite transmission shaft combines the original two sections into one section,cancels a pair of metal universal joints,and the mass is reduced by more than 40%.The bench test results show that the static torsional strength,torsional fatigue life,critical speed and other performance indexes of the product fulfill the requirements of the national automotive industry standard QC/T 29082—2019 Specification and Bench Test Methods of Automobile Propeller Shaft Assembly.
