Abstract
This study describes experimental investigations into the non-linear vortex-excited vibration of a circular cylinder in steady and uniform flow in open chanel with emphasis being placed on the amplification of fluid forces caused by the fluid-structure interaction. The dynamic transverse responses of a spring supported circular cylinder were investigated in the range of reduced velocity Vr=4 to 10 for several values of reduced damping Ksa. The value Ksa of deduced damping was adjusted by using a electromagnetic damper. Hydrodynamic forces, drag and lift, acting on the vortex-excited circular cylinder freely vibrating in uniform flow were measured by using a load cellinstalled in the test cylinder and a load cell supporting the test cylinder. The variation of amplification of the hydrodynamic forces acting on the vortex-excited vibrating cylinder in comparison with the hydrodynamic forces acting on the cylinder stationary mounted at the reduced velocities Vr and amplitudes of transverse vibration of cylinder were evaluated quantitatively.
