This article presents an analysis of the Fluid-Structure response of bladeless wind turbines that work by induced aeroelastic resonance, which can be used in cities or small towns to form part of sustainable urban planning. In it, numerical simulations of the behavior of the wind and the effect called Von Karman Vortices that it produces when surrounding the structure of the wind turbine are carried out, taking as input data the wind speeds measured by the Mariscal Sucre Meteorological Station in Quito. CFD simulations determine the excitation signal caused by the different existing wind flows, the effects that these oscillations cause on the structure are simulated through a modal study and harmonic response to resonance. The results obtained show a proportional increase in the frequency and amplitude of the vortex shedding to the increase in wind speed, causing different excitation signals that cause the wind turbine to oscillate with amplitudes between 6 and 11 cm. Finally, the transient simulations show that the presence of houses and buildings in the vicinity where the wind turbine is installed causes the direction of the vortex street to vary, as well as alterations in the frequency and amplitude of the excitation.
