碳纤维增强塑料（CFRP）具有重量轻、强度高、热膨胀系数小、阻尼比高等优点。以碳纤维复合材料-金属混合传动轴为研究对象，对其振动特性进行了分析。层压模式
CFRP轴管的等效弹性模量、等效剪切模量和模态阻尼设计为[±15°3/ ±45 ° / ± 88 ° / ±88° / ±45° / ± 15°3 /88°]s，
通过理论计算得到了CFRP轴管。通过有限元分析，得到了CFRP轴管扭转振动角的变化规律。此外，对CFRP-金属混合驱动器进行了相同的弯曲振动和扭转振动测量
轴和金属驱动轴使用加速度传感器。测得混合动力传动轴的一阶弯曲共振转速为1094.64 r/min，共振振幅为0.118 mm，测得金属传动轴的一阶弯曲共振转速为1298.2 r/min，
CFRP轴管的最大扭振应力为330.0733 Mpa，远高于金属传动轴的最大扭振应力（125.99 Mpa）。可以看出，CFRP驱动轴具有更高的抗弯曲性，
扭转和振动比金属传动轴。
Carbon-Fiber-Reinforced Plastic (CFRP) has several advantages, such as light weight, high strength, small thermal expansion coefficient and high damping ratio. The CFRP-metal hybrid drive shaft is taken as the study object to analyze its vibration characteristics. The laminate mode
of the CFRP shaft tube is designed as [±15°3/ ±45° / ± 88° / ±88° / ±45° / ± 15°3 /88°]s, and the equivalent elastic modulus, equivalent shear modulus and modal damping of
the CFRP shaft tube can be obtained by theoretical calculation. The change rule of the torsional vibration angle for the CFRP shaft tube is obtained by the finite-element analysis. Furthermore, the same bending vibration and torsional vibration are measured for the CFRP-metal hybrid drive
shaft and the metal drive shaft using an acceleration sensor. The measured first-order bending resonance speed of the hybrid drive shaft is 1094.64 r/min, and its resonance amplitude is 0.118 mm. The measured first-order bending resonance speed of the metal drive shaft is 1,298.2 r/min, and
its resonance amplitude is 0.21 mm. The maximum torsional vibration stress of the CFRP shaft tube is 330.0733 Mpa, which is far higher than the maximum torsional vibration stress (125.99 Mpa) of the metal drive shaft. It can be seen that the CFRP drive shaft has higher resistance to bending,
torsion and vibration than the metal drive shaft.
