  1. By vibration measurement and order proportion spectrum frequency analysis for high rotation speed reciprocating compressor pipe network, vibration causes are searched out, reducing vibration methods and treatment measure are established, after improvement, high vibration amplitude value is reduced greatly for pipe network

    摘要對高速往復壓縮機管網振動進行了測試和階比譜頻率分析，找出了振動原因，確定出實際可行的減振方法和處理措施，經過改造后的機組，原振動較大點幅值得到大幅度降低。
  2. The main research in this thesis can be summarized as follows : ( 1 ) the structure and features of tc620 turbo cycling compressor are introduced. its frequent faults, fault mechanism and diagnosis are also analyzed. ( 2 ) the vibration signal analysis based on fault analysis and processing are presented, including wave analysis, tarce analysis, frequency spectrum analysis etc. and connected signal transformation ideas are also described, which can be conducted in amplitude field, time field and frequency field according to different needs

    本文主要包括以下內容： （ 1 ）介紹了tc620透平循環壓縮機的結構特點，歸納總結了其常見的故障現象，分析了各類故障產生的機理和診斷方法； （ 2 ）論述了基於故障分析處理的幾種常用的振動信號分析法，如波形分析、軌跡分析、頻譜分析等。
  3. 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
