英文摘要：

Carbon fiber composite material has characteristics of light weight,high specific modulus,high specific strength and fatigue resistance.According to the requirements of strength and critical speed,a carbon fiber composite drive shaft which was applied in one type of automobile was designed.The finite element analysis software Abaqus was used to simulate the drive shaft,and the results show the stress,strain and failure distribution of the shaft under torque load.There has average stress and strain distribution in the carbon fiber shaft tube,and the simulation results are in agreement with the design theory and experiment.The mechanical properties of carbon fiber composite drive shaft meet the requirements in automobile.
