  1. With the speed increment, not only 1 / 2x and 2 / 3x frequency component appear in low frequency segment, but also 4 / 3x frequency component begin to appear in high frequency segment. the amplitude of fraction frequency is usually larger than that of multiple frequencies. the nonlinear characteristic of torsion for rubbing rotor is similar with that of flexural vibration completely

    研究結果證實了扭振特徵和非線性特性用於該類故障診斷的可行性:從發生碰摩起,扭振分頻和倍頻相伴出現,轉速較低時, 1 / 2x成分突出,隨著轉速升高,不但有1 / 3x及2 / 3x分量出現,而且出現了4 / 3x成分,分頻幅值大於工頻及倍頻;彎振和扭振的非線性運動特性完全相似,扭振有抑制轉子系統復雜運動的能力。
  2. The natural vibration frequency were obtained by galerkin method and multiple - dimensioned method

    通過伽遼金方法和多尺度法求解,得到了懸索的各階頻率計算式。
