COUPLED CALCULATION OF AIRFLOW INTERACTION WITH ELASTIC ROD OF SQUARE CROSS SECTION FIXED RIGIDLY TO A SUBSTRATE
The study of wind effects on buildins is one of the most important stages of design, since the results of these calculations can prevent the undesired vibrations, damage and destruction of buildings and other structures. The paper presents the results of numerical modeling of vibration of an elastic rod mounted normal to the external flow and fixed rigidly to a substrate. The simulation is performed with ANSYS software using the technology of bidirectional coupling (2-FSI). The hydrodynamic, conjugate and modal analysis have been performed. The structure of the air flow in the vicinity of the model was analyzed. The oscillations of the elastic model were revealed and the stress-strain state was obtained. The natural frequencies of the rod and corresponding vibration shapes are found.
