|
摘要
汽车传动轴是车辆传动系统中的重要部件,在汽车运行中承担传递转矩的任务。从理论出发设计了碳纤维复合材料汽车传动轴,并通过理论-有限元-实验三者结合的方法对设计的某类汽车传动轴进行了详细的分析,论述了碳纤维汽车传动轴的优异性能。结果表明,运用碳纤维复合材料传动轴设计制造的一体式汽车用复合材料传动轴在满足强度需求的同时,其最低临界转速远高于实际转速需求,为车身的安全性与舒适性提供了保障。此外,通过Abaqus有限元软件对设计传动轴振型进行了理论计算,得出了传动轴振型图像以及振幅数值,并通过实验测量出了实际临界转速,为复合材料传动轴设计与运用提供依据。
Automobile drive shaft is important part in automobile drive system,it acts as torque transmission. According to the theory of design,this article designs an automobile drive shaft made of cambon fiber composite and analyzes it in detail in combination with the theory,finite element method and experiment and expounds its excellent properties. The results show that the carbon fiber composite drive shaft meets the demand of its strength at higher critical speed. It can guarantee the safety and comfort of car body. The finite element software Abaqus is used to do the theoretical calculation of the designed drive shaft to obtain the shaft vibration diagram and the amplitude value and the actual critical speed is measured through the experiment. This paper provides the basis for composite drive shaft design and usage.
