  1. The dynamics behaviors of the flexible jeffcott rotor system supported by unsteady short dynamic bearing are investigated. based on nonlinear unsteady - state dynamic n - oil film force model described by three functions the local stability of the periodic solutions with the controlling parameters, rotational speed ratio, imbalance amount, damping ratio and viscidity, are predicted by using the floquet multiplier. it is found that the period doubling bifurcation is caused by a certain imbalance amount and the hopf bifurcation is created by the lost stability of the oil - film

    研究了非穩態動載短軸承支撐的jeffcott柔性轉子系統的動力特性，基於可用三個函數表示動態油膜的非穩態非線性油膜力模型，將轉速比、不平衡量、阻尼比、粘度作為控制參數，利用floquet乘子預測周期解的局部穩定性，發現倍周期分叉是由一定量的不平衡引起的，而hopf分叉是由油膜失穩造成的。
  2. However, b ecause t he d isplacement o f v ibration t able u sed i n t he t est i s 1 imited t o 4cm, the results of the testing could prove only partially the damping effect for ground motions with significant short - period contents

    由於振動臺振動位移的限制，振動臺試驗僅能進行短周期成分豐富的地震動試驗，不能全面地評價斷路器的抗震性能和鉛合金減震器的減震效果。
