| 中文摘要 | Based on previous works, experiments are carried out for effects of harmonic and cone-like disturbances on vortex-induced vibrations (VIV). The structures are designed as the pendulum oscillated transversely in water channel. Three waviness, the ratio of wavy height to the wavelength, of 0.025, 0.05 and 0.1 are presented with the non-dimensional prescribed wavelength of 6. With the increasing incoming velocity, the oscillating amplitude of the wavy cylinder is firstly decreased at the start of synchronization with the comparison to that of the straight cylinder, and then increased greatly at higher velocities. Meantime, the response region of the wavy cylinder is also enlarged with the comparison to that of the straight cylinder. Other characteristics of responses of amplitude and frequency at different incoming velocities are presented. |
