  2. Base on review of existed study and application in suppressing cable vibration in the world, technique of mitigating cable vibration with viscous damper and mr damper has been investigated in this dissertation, and the main contents and progresses in form of summary are as following : 1 the motion differential equations of the cable - damper system are formatted, which take into account these factors, such as the inclined angle, sag, stiffness etc. coupling motion between cable and deck is studied with analytical and numerical method. numerical results show that large amplitude vibration of cable with beat rhythm will occur when exciting frequency of deck equals two times modal frequency of cable

    本文在對國內外斜拉索振動控制研究與應用現狀進行綜合評述、分析的基礎上，針對上述問題進行了深入研究，具體的研究內容和取得的成果包括： 1 、建立了斜拉索-阻尼器系統運動方程，對拉索與橋面的耦合振動作了分析和研究，數值結果顯示當橋面激振頻率等於某階拉索模態頻率的兩倍時，很小的初始擾動將引起拉索的大幅振動，並呈現拍振的特徵，與實測的拍振信號一致。
