Study on the Wind-induced Dynamic Response of Wind Power Tower in Consideration of Fluid-structure Interaction

摘要

Based on Adina finite element software, this paper established elaborate model in consideration of the fluid-structure interaction between structure and air, then compared the stress between on-site monitoring and the simulation which the wind speed is 5m/s. Finally, based on the Davenport wind speed spectrum, this paper analyzed the dynamic response of wind power tower for pulsating wind for 10a, 20a and 50a, and suggested more accurate fluid-structure interaction method when analyzed the wind-induced dynamic response. The study shows: The elaborate simulation method used in this paper is mostly consistent with the on-site monitoring; The FSI method makes a better accuracy than the standardized calculation method; Normal performance of wind power tower structure is determined by the displacement.
