Study on the Fluid-Solid Coupled Wind-induced Vibration of CFRP Cable
Study on the Fluid-Solid Coupled Wind-induced Vibration of CFRP Cable With ANSYS
on the wind-induced vibration of CFRP cable with the consideration of
fluid-solid coupled effect
Abstract: Due to the lightweight
and high strength of Carbon Fiber Reinforced Polymer (CFRP), it has
good application future in large span structures. Since the self-weight
of CFRP cable is very light, more study should be given on its wind-induced
vibration. In this paper, the wind-induced vibration of CFRP cable is
studied with the fluid-solid coupled simulation function of ANSYS, a
common finite element package. Different turbulence models are discussed.
And the responses of CFRP cable in stable and fluctuant wind fields
are simulated. The numerical results show that due to the lightweight
of CFRP cable, the aerodynamic damping effect is more obvious. So with
proper design, the wind-induced vibration of CFRP cables may have better
performance than steel cables with the same size.
