基于刚度灵敏性分析的15MW风力机气弹响应
Research on aeroelastic response of 15 MW wind turbine based on stiffness sensitivity analysis
摘要
Abstract
This study investigates the interactions among loads and the structural properties of offshore wind turbine blades.To examine these interactions,the study developed an aeroelastic model of the IEA15MW turbine based on the geometrically exact beam theory coupled with the blade element momentum theory.A sensitivity analysis meth-od is introduced to quantify the influence of individual stiffness components on the aeroelastic response.Results show that reducing the torsional stiffness to 40%of its baseline increases the tip torsional angle by 57.5%,while both flapwise bending and torsional stiffness exhibit medium-to-high sensitivity.Among coupling terms,both shear-torsion and bend-torsion coupling stiffness are highly sensitive to the effects of all pronounced variables.In particu-lar,reducing the bend-torsion coupling stiffness to 10%results in a torsional sensitivity factor of up to 20.9.These findings clarify the influence patterns of stiffness parameters on blade aeroelasticity and offer guidance for optimizing the structural design and stiffness of offshore wind turbine blades.关键词
