Rotating through means of supporting the eccentric shaft housings can be high - power output shaft axis and the distance between completely exclude sleek phenomenon
通過旋轉支撐入力軸的偏心軸承座可高速入力軸和出力軸之間的距離，能完全排除不滑順的現象。Firstly, the relationship of atomic force and distance is studied. the scan type of samples and the working mode of probe is confirmed, then pzt is chosen as actuator for micro scan displacement, and optical deflexion method is used to detect the deflexion value of cantilever. after all these work, the system light path design is finished, and its mathematical model is completed
首先，分析了原子力探針系統的中原子力?距離的關系，並確定探針系統的探針的工作模式和樣品的掃描模式，從而選擇壓電陶瓷作為掃描微位移驅動器;採用光學偏轉法檢測微懸臂偏轉量，並選用了psd作為傳感元件，並在此基礎上進行了系統光路設計及其數學模型的建立。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。Under the direction of elastic - plastic statics theory, transient dynamics theory and structure mechanics theory, the means of numerical analyse is adopted in this thesis to study the security of existing tunnel. the thesis studies the contents as follovvs : ( 1 ) the bias pressure, vvhich is caused by the digging of new tunnel, deflects and deforms the lining of existing tunnel. the effect degree relates to tunnel space, construction method, topography and round rock
本文用數值分析的手段，對既有隧道的安全性進行了彈塑性靜力分析、瞬態動力學分析和結構力學分析，如下： （ 1 ） 、新建隧道的開挖對既有隧道造成偏壓影響，使得既有隧道發生偏轉和變形，從而對隧道襯砌產生不良後果，其影響程度與隧道間距、施工方法、地形和圍巖狀況有關。分享友人
