  1. 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。
  2. Moreover, the components of the radial acceleration are theoretically derived, and the processing methods such as the signal sampling, the dynamic marking and storing, the noise removing, the slope comparison and the onset detection of braking operation are described

    文中對加速度傳感器信號的組成進行了理論推導，並闡述了傳感器信號的采樣、動態標注和存儲、平滑去噪、斜率比較以及制動起始時刻判定等的處理方法。
  3. One new method that the uwb signal can be received ambiguously has been presented in this dissertation. furthermore, the sampling lfm signal becomes two sine signals with different frequencies based on two different delay processes. based on fft and remainder algorithm, the modulation rate and initial frequency of sub - sampling lfm signal are estimated precisely and unambiguously in negative snr

    該方法通過在數字域對信號進行兩路不同的延時和余數定理實現欠采樣條件下超寬帶線性調頻信號的調制斜率和初始頻率的無模糊估計，在不降低參數估計精度的前提下，解決了欠采樣方法引起硬體復雜度增加的問題。
