摘要
碳纤维复合材料具有比重小,比强度和比模量高,耐疲劳等特点。针对某汽车传动轴的强度和临界转速要求,设计了一种碳纤维复合材料汽车传动轴,并采用Abaqus有限元分析软件对传动轴进行了仿真分析,仿真结果显示了复合材料传动轴在受扭转载荷情况下的应力应变分布情况以及失效情况,碳纤维轴管应力应变分布均匀,仿真结果与设计理论相吻合,并与实验结果相验证,说明所设计的碳纤维复合材料传动轴的性能可以满足汽车传动轴的要求。
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.
