Abstract

Submarine Pipeline is used widely in ocean engineering now. In order to study the mass ratio’s effect on the submarine pipelines’ vortex-induced vibration, two-degrees-of-freedom vortex-induced vibrations of the pipelines with large and small mass ratio are simulated with the software ANSYS-CFX. When the mass ratios are 7.08 and 3.2, the lock-in, beat and phase switch phenomena were caught in the experiment. The effects of mass ratio on VIV were discussed. Besides, the trajectories were observed with different mass ratios. The research provides a theoretical basis for engineering practice.
