| 摘 要： | 本文应用叶片特征截面法,建立了叶片双自由度弯扭耦合动力方程,计入轮盘行波运动相位角影响,引入非定常气动力载荷,研究均匀叶片转子与具有交叉错频分布的非均匀叶片转子的稳定性。研究了非均匀叶片转子抑制颤振的机理及其影响因素。研究是借助于某发动机压气机一级叶片为计算模型。计算结果表明,非均匀叶片转子具有抑制颤振发作的效能。

| Abstract: | The equation of motion which govern the aeroelastic behaviour of the mistuned blade rotor in which the blade is modelled as two degree-of -freedom vibrational body is formulated. The stability of the tuned and alternate mistuned blade rotor is studied. The key link and the influential factors that the mistuned Made rotor is more stable than tuned one are analyzed. |
