运用修正的叶素－动量理论和有限元方法，建立了一种全新的考虑气动弹性的风力机叶片性能分析方法。运用该方法，在多种风速工况下对某850 kW风力机叶片的性能进行了计算，结果表明：对于大功率风力机，在大风速大载荷工况下，气动弹性对风轮性能有明显的影响，使叶片偏离原设计值。该方法的运用对于叶片的气动设计、载荷计算和结构设计有实际指导意义。

A novel approach , which utilizes a modified blade element-momentum theory and the finite element method, is presented to analyze the blade performance of wind turbine considering aeroelasticity .Then, the ap-proach is used to analyze the performance of the blades of an 850 MW wind turbine at various wind speeds .The re-sults show that aeroelasticity obviously influences the performance of large-size wind turbines at high wind speed and greatly reduces the accuracy of the original design .The presented approach is of guiding significance for the aerody-namic shape design , load calculation and structural design of blades .
