Numerical Analysis of the Vibration of an Elastic Beam Using a Wake Oscillator Model
نویسنده
چکیده
The vibration of an elastic beam experiencing vortex-induced vibration is numerically analyzed through a wake-oscillator model using the finite differences method. The influence of the excited mode, the initial velocity, the shedding pulsation and the mass ratio on the energy transfer among modes and the vibration amplitude is determined. Multiple frequencies are detected, and the power spectral density of the beam tip time series is employed to determine the dominant frequency.
