3. the different forms of oil whip presented in engineering practice are verified by the numerical examples from nonlinear theory. the influence of different mass eccentricity, rotating speed, bearing load and external damper are numerical studied also
運用數值積分的方法，對油膜振蕩的發生、發展、失穩機理及諸多影響因素進行分析，從理論上深層次揭示工程實際中表現出來的油膜振蕩形式的多種多樣性。 -
The numerical results show that : with the enhancement of er effects, the bearing capacity is obviously increased ; the increase magnitude is larger when small radius clearances and large eccentricity ratios ; at low shear rates, the influence of er effects on the lubrication performance of journal bearings are more obvious
數值研究表明：隨著電流變效應的增強，軸承潤滑油膜的承載能力明顯提高；軸承半徑間隙越小，偏心率越大，軸承承載能力增加的幅度也越大；在低剪切速率下，電流變效應對軸承潤滑性能的影響較大。 -
Through careful analyses the author is able to conclude that the primary reason leading to niederkorn & ottino ' s incorrect conclusion is the numerical errors of velocity fields in their calculations and the errors of eccentricity in their experiments
分析表明，流場計算數值誤差和實驗偏心距誤差是niederkorn & ottino得出不正確結論的主要原因。 -
The threshold speed and the typical characteristics of the oil whip of the system are simulated under the nonlinear model of oil film force, and the state of motion and type of the bifurcation are analyzed by floquet multiplicators which is computed by the shooting method. secondly, the the nonlinear dynamical model of the low - pressure rotor - bearing system by column bearing with reduced dimensions is presented. the numerical results show the rule of the amplitude with the eccentricity of rotor, the length - to - diameter ratio, oil viscosity and the clearance - to - radius ratio of the bearing under the definite speed
其次，對降維后的低壓轉子?軸承系統的非線性動力學方程，計算了圓柱瓦軸承支撐的轉子系統的振動穩定性在固定轉速下隨偏心距、軸承長徑比、潤滑油動力粘度和軸承間隙比的變化規律，並分析了轉子前軸承軸頸的失穩轉速與轉子偏心距、軸承長徑比、潤滑油動力粘度和軸承間隙比之間的關系，同時利用floquet理論分析其運動狀態和分岔類型。 -
By numerical simulations the author found the eccentricity produces very large effects on the chaotic mixing. when the eccentricity is high, there always exist very large regular zones in time - periodic flows and these regular zones ca n ' t be removed in aperiodic flows. the optimal configuration is that the dimensionless eccentricity is 0. 5
數值模擬發現偏心率對混沌混合結構有很大的影響，偏心率很大時，常規區總是存在，而且非周期序列並不能消除這些常規區，分析表明，偏心圓筒內二維時間周期和對稱破壞序列混沌混合最佳的幾何條件是無量綱偏心率在0 . 5附近時。
