Using analytical and numerical methods the local stability, the bifurcation and long term behaviors of the imbalance rotor dynamic system are investigated in a wide range of various parametric configurations. it is concluded that the results of both of the two methods are the same for analyzing local stability of the periodic solutions. but after the bifurcation of the periodic solutions the dynamic behaviors of the system with the parameters changed only can be analyzed by numerical method
利用理論與數值方法，在較寬的參數范圍內研究了不平衡柔性轉子系統運動的局部穩定性、分叉和長期性態，結果顯示二者在求周期解的局部穩定性是一致的，但數值方法可分析周期解分叉以後系統隨參數變化的動力特性，這是floquet理論的局限性。 -
Finally, the wave equation of the electromagnetic field of this kind damper is derived from the maxwell ' s equation. the magnetic flux density at the boundary is assumed to be harmonic, so the analytical result of the wave equation is solved. when the rotor rotates, eddy currents flowing inside the conducting material field are caused
最後，應用ahrens的電磁軸承簡化模型，從maxwell方程出發推導了應用於本文所述的被動式電磁阻尼器的波動方程，並用傅立葉級數把矩形磁場展開的諧變磁場作為磁場的邊界條件，通過求解波動方程得到磁場的解析解，從而計算了阻尼器對轉子的電磁力和由渦流引起的切向力產生的阻尼器附加功耗。 -
