摘要

Vortex-Induced Vibration (VIV) is a familiar phenomenon which can be encountered in many practical fields, particularly in ocean engineering. While VIV occurs, the structure interacts with the fluid. The fluid exerts oscillatory drag and lift forces on the structure, causing the structure to oscillate or move rigidly. Meanwhile, the oscillating structure influences the fluid in turn, by changing the fluid forces. If the vortex shedding frequency is close to a natural frequency of the structure, the resonance takes place, resulting in large-amplitude oscillation. This phenomenon is defined as lockin. The lock-in phenomenon can ultimately lead to structure failure. Therefore, it is of great significance to investigate the mechanism and characteristics of VIV in the design of offshore and deep-sea structures. The researches accomplished in the past decades on the characteristics of VIV have been comprehensively reviewed in Sarpkaya (2004),Gabbai and Benaroya (2005), Williamson and Govardhan (2008) and Wu et al. (2012).
