风力机叶片截面运动稳定性的数值分析

Numerical Value Analysis of Movement Stability of Wind Turbine Type Blade

用数值方法绘出叶片振动的时间位移响应曲线,根据响应曲线得出叶片运行状态,进而确定影响风机叶片气动弹性稳定性的物理因素和关键参数。

The numerical method is to be used to map the time displacement response curve, in accordance with the corresponding curves get the running＇ s state , and then to determine the physical factor and key parameter for impacting the blade＇ s aeroelastic stability .
