Therefore, in the research of turbomachinery aeroelastics, it is more and more important to predict bladeflutter and to avoid bladeflutter.
所以，预报颤振发生几率，避免叶片颤振的研究工作在叶轮机械气动弹性力学学科中占有越来越突出的地位。

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 bladeflutter.
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。

Through the computation and analysis of unsteady aerodynamic forces loading on the cascades and aerodynamic work, the probability of bladeflutter is predicted through the energy method.
