对风力涡轮机叶片在指定的流场压力场下的变形提出一种新的分析方法。利用多重参考系模型，研究叶片表面的受力和叶片周围流场的变化，对风力涡轮机叶片进行单向流固耦合分析。叶片在12 m／s风速下的数值模拟结果显示叶尖部分压力最大。该方法既能真实模拟叶片运行时的状况，又能节省计算时间，提高效率。

It presents a new method for analyzing the deformation of wind turbine blade in particular flow field and pressure field.With the multiple reference frame model, this paper researches the pressure distributions on blade surface and the changes of the surrounding flow field, analyzes coupling characteristic fluid-solid interac-tion of wind turbine blade, provides numerical simulation result for the most pressure on blade tip in 12m/s wind.This method can not only simulate the situation of blade runtime realistically, but also reduce the calcula-tion time and increase efficiency.
