中文摘要 | 本文探討非對稱轉軸具剛性非對稱轉盤之動態穩定性。非對稱轉軸之動態方程式表示成連續形式,並以連續模態求解。本文利用解析法求解臨界轉速以及同步、超諧迴旋之不穩定邊界。在轉動座標中,以此法得到正確解。並以例題說明轉盤非對稱性結合轉軸非對稱性對穩定性之影響。 |
英文摘要 | The dynamic stability of asymmetric shafts with rigid asymmetric disks is studied in this paper. The governing equation of the asymmetric shaft is expressed and solved in a continuous form. Ananalytical method is developed to determine critical speeds and instability boundsries of synchronous, superharmonic whirls. The closed-form soulutions can be obtained in the rotating frame. The influence of disk asymmetry togethe with shaft asymmetry is evaluated by numerical examples. |
