摘要：
Aero-elastic model wind tunnel test is carried out for a 1/3 rise-span ratio capsule-shaped pneumatic membrane struc‑ ture，the characteristics of the wind-induced aero-elastic response of the structure are studied and the wind-induced dynamic vibra‑ tion coefficients for practical design reference are given. The research confirms that the averaged deformation of the structure shows a trend of windward depression，top uplift and outward bulge in the transverse direction. This deformation trend is increasingly ob‑ vious with the decrement of internal pressure and the increment of wind speed. The averaged deformation and vibration amplitude decrease when the wind direction ranges from 0° up to 45°，then to 90°，and the extreme value of structural mean total displace‑ ments tends to appear at the center points of windward surface and top surface. Under 0° and 45° wind directions，the sort of vibra‑ tion amplitudes of different components is vertical component，along-wind component and cross-wind component in descending or‑ der. Moreover，the structural vibration is dominated by the first-order mode. Under 90° wind direction，the amplitude of the cross‑ wind direction is greater than two other directions，and the wind-induced vibration is dominated by the superposition of the first and second order modes. The internal pressure of the structure decreases in different extents under all cases. The response-based wind-induced dynamic vibration coefficients considering the fluid-structure interaction effect are given. © 2024 Nanjing University of Aeronautics an Astronautics.
