摘要: 从流体动力学出发,应用动量定理研究汽轮机直叶片由于间隙引起的气流激振力问题,综合考虑了叶片的各项设计参数并应用理论分析的方法导出普遍适用的计算公式,解决了Alford公式中需人为选取效率系数的困难。通过与Alford公式计算结果的对比计算表明该计算公式是正确的,计算结果是可信的。

Abstract: Based on the hydrodynamics, the air exciting – vibration force of turbomachinery caused by clearance is studied by using the momentum theorem. A computational formulation consisted of the design parameters of vane is educed and it has solved the difficult of selecting efficiency factor in Alford formulation. It can be seen that the presented formulation is correct and the computational result is believable.

Key words: Air - flow, Dynamics, Exciting – vibration force, Rotor
