摘要
风机叶片正向超大型化、轻质化和高性能化方向发展。高效率的风电机组必然要求高性能的风轮叶片,气弹剪裁则是获得高性能叶片的一种有效方法,而弯扭耦合是实现气弹剪裁的一种途径。本文通过研究弯扭耦合的控制参数,建立了弯扭耦合的理论估算公式,并对现有750kW叶片主梁重新进行弯扭耦合设计。研究结果表明,碳纤维取代玻纤单向布对主梁的重新设计,将大大提高叶片的整体性能。
Wind turbine blade will be developed to be bigger, less weight and higher performance. High performance blade is needed for the high efficient wind turbine. Aeroelastic tailoring is an effective method to design high performance blades, bend-twist coupling is one of the way to realize aeroelastic tailoring. This paper builds up the theoretic equation of bend-twist coupling through study on the control parameters. Redesign of 750KW-bladespar-cap is made using bend-twist coupling method, in which glass fiber is replaced by carbon fiber, results show that the whole blade performance will be improved greatly.
