摘　　要：根据机床传动轴的设计参数,设计了碳纤维传动轴,确定了铺层层数及厚度。在此基础上,根据碳纤维布的铺层原则,制定了6种铺层方案,通过比较几种方案的变形和应力分布,从中选取最优铺层方案。运用ANSYS有限元仿真软件,对设计的碳纤维复合材料传动轴,进行静态扭转分析和模态分析,得到其扭转性能参数和固有频率,根据仿真结果可知设计的碳纤维传动轴能够满足机床传动轴的使用要求。A carbon fiber composite material propeller shaft was developed,its stacking layers and thickness were determined according to the design parameters of the machine tool propeller shaft.On this basis,six different stacking sequences were developed with the stacking principles of carbon fiber cloth;the optimal stacking sequence was chosen by comparing the strain and stress distribution of those different stacking sequences.The finite element analysis software ANSYS has been used to analysis the static torsion and modal of the designed carbon fiber composite material propeller shaft,acquired its torsional performance parameters and natural frequency.The simulation results showed that the developed carbon fiber composite material propeller shaft could meet the usage requirements of propeller shaft for heavy machine tool.
