叶片颤振属于流体诱发振动现象，是叶片振动的另一种形式。弹性体的叶片在气动力作用下形成的气弹耦合的自激振动，称为颤振。
不同二次流与叶片颤振的相关性中尖部漏流涡对叶片气弹稳定性的影响较大。
The tip leakage vortex may have greater effect than other vortexes, that is consistent with the experimental results.
计算结果表明，漏流涡对叶片气弹稳定性影响较大，大涡量的漏流涡能抑制叶片颤振发生。
The results show that the tip leakage flow vortex has a great effect on the blade aeroelastical stability and large tip leakage vorticity may restrain blade flutter.
