Аннотация:Motion of elastically supported bluff body under the action of airflow is
considered. It is supposed that the body can perform translational motion in the
direction perpendicular to the flow. In order to describe unsteady aerodynamic effects,
the empirical model is used that was developed earlier for simulation of dynamics of
aerodynamic pendulum. Limit cycles appearing in the obtained dynamic system are
analyzed. Dependence of their amplitude and frequency upon the flow speed is
studied. Influence of model parameters upon the characteristics of the cycles is
studied. It is shown that simulation results are in qualitative agreement with available
experimental data.
