摘　　要：分析了水平轴风力机转子桨叶所受的外力和外力矩,给出了桨叶的动力学模型,并推导出桨叶俯仰振动、扭转振动和摆动振动方程及相应的一阶振动固有频率。探讨了有关参数对三个方向振动固有频率的影响。对风力机桨叶的设计计算提供了动力学依据。This paper analyzes forces and moments acting on blades of the rotator of a wind turbine.It gives a dynamic model of the blades and deduces their pitching/torsional/swinging vibration equations as well as corresponding first-order natural vibration frequencies.It also discusses effects of relevant parameters on the natural vibration frequencies in the three directions.Thus it provides a dynamic basis for calculation for wind turbine blade designs.

关 键 词：风力机 桨叶 振动方程 固有频率
