  • 旋轉(zhuǎn)中心
  • 轉(zhuǎn)動中心

Examples

  • Conclusions : with the horizontal alveolar loss , the rotation center moved toward the apex and the capacity of periodontal support decreased significantly
    結(jié)論：隨著牙周支持組織高度的逐漸降低，牙的旋轉(zhuǎn)中心向根尖移動，牙周支持組織對牙的支持能力明顯減弱。
  • In succession , we should test whether the rotation center of the tri - eccentric butterfly vavle was right , brought forward a method to test the seal fit interference , designed the program about the seal fit interference and gave the corresponding results which the program was run
    對于三偏心蝶閥回轉(zhuǎn)中心的選擇是否合適，本文提出了一個檢查密封副干涉的方法，設計了相關(guān)的程序并進行了驗證，給出了程序運行的部分結(jié)果。
  • The paper analyzed the struture of the tri - eccentric butterfly vavle at length , defined the tri - eccentric butterfly valve , educed the geometry function and its characteristic about the section of the butterfly disc . the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse , thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body , combining the torque , we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle
    本文主要分析了三偏心蝶閥的結(jié)構(gòu)，給出了三偏心的定義，推導出了蝶板截面的幾何方程及其性質(zhì)，結(jié)果表明，沿蝶板厚度的平行截面輪廓線為標準的橢圓形，進而推導出了蝶板幾個主要截面的幾何參數(shù)(長軸、短軸)與三個偏心之間的函數(shù)關(guān)系；考慮到蝶板啟閉過程中避免與閥體及閥座發(fā)生干涉，結(jié)合蝶板的啟閉扭矩，確立了三偏心蝶閥回轉(zhuǎn)中心的適宜區(qū)域。
  • Because it is impossible to adjust the air bearing absolutely balance , the difference between mass center and rotation center must lead to a notable gravity disturbance torque . in the process of identification , modeling and identification of gravity disturbance torque is considered , and an extended kalman filter is educed for identifying air bearing inertia matrix and gravity disturbance torque , and then the algorithm is validated
    由于氣浮臺平衡調(diào)試方法和手段的限制,實驗過程中氣浮臺質(zhì)心與轉(zhuǎn)動中心有一定的位置偏差,必將導致較大的重力干擾力矩,在辨識算法的推導過程中,重點考慮了重力干擾力矩的建模和參數(shù)辨識問題,推導了氣浮臺的轉(zhuǎn)動慣量和重力干擾力矩辨識的擴展卡爾曼濾波算法,并對算法進行了數(shù)學仿真和全物理仿真驗證。
  • The air bearing is the most important part of an attitude control system simulator for simulating a satellite moving in the weightless circumstance . performance of a satellite attitude simulation system based on air bearing is decided by the inertia matrix and gravity disturbance torque arising from a difference between mass center and rotation center , and air bearing can be used to simulate the algorithm of on - line mass - property parameters identification on the ground . so the problem of mass - property and gravity disturbance torque identification for satellite and air bearing is studied in this thesis
    氣浮臺能夠模擬衛(wèi)星在軌失重條件下的姿態(tài)運動,是衛(wèi)星姿態(tài)控制系統(tǒng)物理仿真的核心部件,其轉(zhuǎn)動慣量和質(zhì)心偏移引起的重力干擾力矩等決定了基于氣浮臺的衛(wèi)星姿態(tài)物理仿真系統(tǒng)的性能,并且利用氣浮臺可以實現(xiàn)衛(wèi)星質(zhì)量特性在線辨識算法的地面物理仿真驗證,因此本文對衛(wèi)星和氣浮臺的質(zhì)量特性及干擾力矩在線辨識問題進行深入研究。
