基于流固耦合的风电机组预应力模态分析
Pre stress Modal Analysis of Wind Turbines Under Fluid structure Interaction
摘要
Abstract
Taking a pleavy wind driven generator as an example and considering the rotation of blade load and fluidstructure coupling effect,this paper uses the finite element software ANSYS Workbench to conduct prestress modal analysis of the wind driven generators. Firstly the pressure of flow field is obtained under the effect of blade wheel load and fluidstructure coupling and by CFD analysis for its outflow field,then the static structural analysis is conducted and the data is transtered to the modal analysis under the prestress. The results indicate both modal frequency and mode of vibration are changed under the condition fluidstructure coupling apparently.关键词
