摘要
根据风机气动相关理论,进行叶素空气动力学特性分析,并给出叶片气动力的计算表达式,采用ANSYS有限元分析软件对风机叶片模型进行振动模态分析,计算了叶片的固有频率、各阶振型图,为避免叶片发生共振、提高叶片使用寿命提供了分析方法。
Some aerodynamics characteristics analysis of airfoil had been done according to some wind turbine theories.Then the expressions of aerodynamic forces were given.Modal analysis were achieved by ANSYS software,and the natural frequencies,each vibration modes are also calculated.These study can supply analysis method for preventing blade resonance and increasing blade working life.
