摘　　要：文中首先结合国内外研究进展情况概括总结了大型风力机叶片气动弹性等效梁建模理论,以及解决风力机叶片气动弹性稳定性问题的常用方法:BEM方法、动态失速模型和CFD方法。其次,对在现代大型风力机叶片设计中颇受关注的,智能材料在风力机叶片结构颤振及振动主动控制中的应用研究现状也给予了简要的介绍。最后指出一些尚待进一步研究的问题,以及今后的发展方向。Firstly, by combining with the situation of researching headways at home and abroad, the modelling theory for equivalent beam of the aero-elasticity of large scaled wind turbine blade and the commonly used method： BEM method, dynamic stalling model and CFD method used for solving the aero-elasticity stability problem of wind turbine blade were briefly summarized. Secondly, a brief introduction was given on the current situation of application research for the intellectual material, that a considerable attention has been paid in the design of modern large scaled wind turbine blade, used in the structural flutter of wind turbine blade and the initiative control of vibration. Finally, some problems need to be further studied and henceforth directions of development have been pointed out.
