大型水平轴风力机新型叶片结构设计思想和研究进展

CONCEPT AND DEVELOPMENT OF NOVEL BLADE STRUCTURE OF LARGE HORIZONTAL-AXIS WIND TURBINE

  • 摘要: 该文首先阐释了在风力机大型化发展过程中叶片结构设计的主要问题在于大型叶片对综合结构性能的高要求与轻量化、气动性能之间的矛盾,传统悬臂梁结构叶片的承载特性限制了叶片进一步大型化发展的空间,新型叶片结构的设计开发是解决这一问题的有效手段。新型叶片结构的设计思想按其着眼点主要包括仿生柔性设计思想、分段设计思想和局部附加结构的设计思想等。在此基础上,该文综述了近年来新型叶片结构的研究进展,为大型叶片结构设计提供了参考。

     

    Abstract: During the development of large-scale horizontal axis wind turbines, the major problem is the contradiction among the structure reliability and the requirement of light weight and aerodynamics efficiency. The structural characteristics of a traditional cantilever blade has restricted the further development of large wind turbines. The novel form of a blade structure is the effective solution to the problem, such as bionic flexible blades, segmented blades and multi-element blades. This paper reviews the state of the art of novel blade structures in recent years, providing some references for large blade design.
