摘要
运用ANSYS参数化设计语言,建立具有真实气动外形和复合材料铺层的高精度有限元壳结构模型,并且在Matlab平台调用、耦合基于BEM理论建立的气动模型,从而构建风力机叶片气弹分析模型。充分考虑叶片实际受载情况,对100 kW风力机叶片进行弯扭耦合加载气弹分析,求解了耦合与非耦合情形下风力机的响应、功率系数和弯矩等,总结不同风速下气弹耦合作用对于风力机的影响,并对风力机叶片设计提出改进措施。
High precision finite element（FE） shell model are built by Ansys parametric design language（APDL）,real aerodynamic profile and composite layups are included in the model,and based on the Matlab platform,the aeroelastic model of wind turbine（WT） blade is established by coupling traditional BEM theory and FE model.Taking the in-service load cases into account,the aeroelastic response,power coefficient and bending moment in the coupling and uncoupling case of 100 kW WT with bend-twist coupling blade loads are analyzed.Summarizing the influence of aeroelastic coupling on blade under different wind speeds,then,make some improvements for the design of wind turbine blade.
