摘　　要：碳纤维增强复合材料(CFRP)具有优异的综合性能,近年来已被广泛应用于各种主承力件和次承力件的制作。本文引入黏弹性高阻尼橡胶与CFRP结合设计了高阻尼复合材料传动轴,基于模态应变能法,利用数值分析研究了所设计的高阻尼复合材料传动轴、CFRP轴与金属轴的阻尼损耗因子,并通过自由振动试验验证了数值分析的结果。在船用传动轴系中易出现各类振动,本文搭建了船用传动轴系横向振动测试试验平台,比较了各组传动轴在不同工况下对横向振动的减振效果,并通过静态纵向振动试验研究了各组传动轴对纵向激励的响应差异。本研究对高阻尼复合材料传动轴的设计研发提供了参考。Carbon fiber reinforced plastics(CFRP)have excellent comprehensive material properties and have been widely used in the fabrication of various primary and secondary load-bearing parts in recent years.In this paper,a high-damping composite driveshaft is designed by combining viscoelastic high-damping rubber material and CFRP material.The damping loss factor of the designed high-damping composite driveshaft,CFRP shaft,and metal shaft is studied by numerical analysis based on the modal strain energy method.In the marine driveshaft system,various types of vibration are prone to occur,and this paper also builds a marine driveshaft system transverse vibration test platform to compare the damping effect of each group of driveshafts on transverse vibration under different working conditions.At the same time,the difference in response to longitudinal excitation of each group of driveshafts is also investigated by static longitudinal vibration test.This study provides a reference for the design and development of high-damping performance composite driveshafts.
