Abstract: 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.
