Abstract

This paper presents experimental and numerical study with the objective of exploring the effect of suction control on vortex-induced vibration (VIV) of a bridge deck. The vertical and torsional responses of the model with or without suction control during this experiment were measured. The results demonstrate that the suction decreases the vibration amplitudes. The suction holes arranged on the undersurface near the leeward of the model has the best effect. To study the mechanism of the suction control, the aerodynamic stability of the model is analysed by the forced vibration method. The results demonstrate that the aerodynamic stability of the model is increased by the suction control.
