Vortex Effect of Optical Cables
Vortex-induced vibration is the resonant, small-amplitude vibration caused by steady, low-velocity wind blowing across cables under mechanical tension. The results show that in the submarine cable, there appears to be a beating vibration and locking phenomena respectively. Under the current scouring, submarine cables are prone to be exposed, suspended, and even vortex-induced vibration (VIV), threatening their mechanical and electrical proper-ties. In this contribution, a finite element simulation model of 110-kV single-core optical fibre composite submarine cable is.
