气动力和离心力载荷对风力机叶片结构特性的影响
|
摘要
采用雷诺平均NS方程和标准k-ε湍流模型,在不同风速和转速下对某风力机叶片基于Workbench进行了单向流固耦合数值模拟,分别分析了气动力载荷和离心力载荷对风力机叶片功率及风力机叶片结构特性的影响。结果表明:相对于气动力载荷,风力机叶片离心力载荷对风力机叶片结构特性的影响较大。
The one-way fluid-structure coupling performances of wind turbine blades under different wind speeds and different rotation speeds were investigated by solving Renault average NS equations combined with standard k-εturbulence model. Influences of aerodynamic and centrifugal loads on the power and structure performance of wind turbine blades were analyzed respectively. The computed result shows that: compared with the aerodynamic load,the centrifugal load on the wind turbine blades has a greater influence on the structural characteristics of the wind turbine blades.
