摘要
为了在工程应用中快速方便地处理风力机叶片的气动弹性问题,往往需要将具体的风力机叶片进行适当的简化处理。该文由此目的出发,通过对以往经验的归纳分析,得到在地面固有频率测试时风力机叶片模型可简化为以相对半径0.500处截面为特征截面的等截面梁,而实际工况下的风力机叶片模型可简化为以相对半径0.875处截面为特征截面的等截面梁,以方便今后风力机叶片气动弹性问题的快速工程建模分析。最后与风力机工程中解决叶片气动弹性问题惯用的建模方法进行比较,以验证其合理性。
In order to solve aeroelastic problem of wind turbine blade quickly and easily, often need to simplify the wind turbine blade lnodle. Based on past experiences, this paper get the simplified engineering aeroelastic wind turbine blade modle on the ground to 0. 500 relative bending radius section as uniform beam regular section. And actual conditions of the machines can simplify the model with a radius of 0. 875 relative bending radius section as u- niform beam regular section to make fast engineering aeroelastic analysis. Finally comparing with past experiences about aeroelastic wind turbine blade model,this paper verifies its rationality.
