Hysteretic Instabilityse from internal hysteresis of the shaft material. As many modern rotors are complex assemblies of components, the conditions under which assembly or material hysteresis may give rise to unstable whirling are of great interest (see figure 1).作者: 彎曲的人 時間: 2025-3-22 02:34
Fluid Instabilitytate equilibrium position. The speed beyond which the shaft becomes unstable and the whirl orbit begins to increase in diameter with time is defined as the threshold speed. Fluid-film instability is strongly influenced by the type of bearings which support the rotor, and by the relative flexibility of the rotor itself.作者: Encoding 時間: 2025-3-22 07:18
Technology, Mathematucs, and industry,ch inherently contains more non-rotating velocity damping. It should be noted that the increase of any damping which rotates with the shaft itself has a stabilizing effect below the bending critical speed, and a destabilizing effect above the bending critical speed.作者: Harpoon 時間: 2025-3-22 12:23
