Abstract

To investigate the wind-induced vibration characteristics and stability of large-span flexible PV support structures under typhoons, a weather forecast model （WRF） based on the nonhydro-static equilibrium Euler equation model was used to simulate three-dimensional near-surface typhoon with the high spatiotemporal resolution, using a customized field function to incorporate a meso-scale typhoon as the inlet boundary condition for small-scale computational fluid dynamics（CFD） numerical simulations; Three structural optimization models were proposed based on a certain project of a 40 m large-span flexible PV support array. The wind pressure distribution characteristics and nonlinear wind vibration characteristics of large-span flexible PV support arrays under typhoons were investigated, and the entire process of structural instability of different optimization models was analyzed. Finally, a structural instability assessment model of large-span flexible PV support arrays was established. Research has shown that the maximum wind pressure of the large-span flexible PV support array occurs in the windward first-row area, with a maximum wind pressure coefficient of 0.85, and the minimum wind pressure occurs in the second row, with a minimum wind pressure coefficient of 0.15; The total displacement of different structural models is mainly in the Z-direction, and the structure is the first to fail in the local triangular braces of the first row of side spans on the windward side. The instability determination model shows that considering cross-diagonal braces and horizontal links is the optimal configuration for large-span flexible PV support arrays.
