電樞是旋轉磁場交流發電機的不動部分(定子) 。In large rotating machinery using filmatic bearing ( turbogenerator, air compressor, etc. ) there is a potential trouble from impefect installation or running conditions, a metals " contact between rotors and shells. the trouble is usully called rubbing. the advantage of ae technologe in the rubbing diagnosis and early detection is showed. instead of classical ae characteristic parameters ( counts, amplitude, energy, duration and the other ones ) a new feature extraction by frequency analysis of ae envelop signals is discussed. both research of ae process and field experements indicate that periodic components in the envelop spectrum related to rotational speed increase evidently at the beginning of rubbing production, hence are highly sensitive to the rubbing fault diagnosis. according to the new design an acoustic emission equipment for the rubbing diagnosis named buaa ae testing system is developed and described
汽輪發電機、空氣壓縮機等採用油膜支撐的大型轉動機械,由於安裝或運行中的原因,在轉子旋轉過程中,可能和器壁發生輕微的摩擦和碰擊,簡稱碰摩.聲發射技術在碰摩發生特別是故障早期診斷上有優越性.本系統的特點是沒有沿用傳統的計數、幅度、能量和持續時間等聲發射特性參數,而是在聲發射包絡信號的頻率分析中進行特徵提取.聲發射發生的過程分析和現場試驗都表明這種方法對碰摩檢測很敏感,在碰摩發生的起始階段,包絡譜中與轉速同步的周期性分量顯著增加.根據這種新的設計思想自行研製了buaa碰摩聲發射檢測儀並對此作了介紹In the latest years, people have designed and made many types of magnetic micromotors, but there are still many problems and much work w hich needs to do about the working principal, design theory and experimental research of magnetic micromotors, this dissertation was just aimed at these problems and did following work : first, on the basis of analying and comparing the working principals and structures of available magnetic micromotors, this dissertation proposed a new type of magnetic micromotor, introduced its structure, controlling methods and the features. according to the basic principles of the fixed - point movement of the rigid body, the dissertation revealed the moving relationship between the rotation of the inner magnetic field of the motor and the rolling of the rotor, presented the moving equation of the rotor and the calculation formula for the rotation ratio between the the inner magnetic field and the rotor, and so made clear the relationship between the structure parameters and the moving characteristics of the motor
