Under windows nt and labview development environment, using the linear fit module, exponential fit module > general polynomial fit module of labview to design a method for fitting the experiment data, the results of curve fitting indicate that the purpose of general polynomial fitting is better than the rest. separating the equivalent input impedance of magnetostrictive transducers without stimulate current from input impedance of it with stimulate loop based on the results of curve fitting, and determining the syntony frequency and electric simulation network parameters of magnetostrictive transducers by this input impedance. finally, with labview network functions, realizing magnetostrictive transducer electric simulation system based on web server and discussing a scheme for this system network by datasocket. the method of this paper can more accurately determine the syntony frequency and electric simulation network parameters of magnetostrictive transducers than the testing method of syntony & anti - syntony. at the same time, discussing virtual instrument measurement system and how to realize magnetostrictive transducer electric simulation network system by labview network functions of network virtual instrument measurement development environment
在windowsnt系統環境和labview虛擬儀器技術開發平臺下,首次利用labview中的直線擬合模塊、指數擬合模塊以及多項式擬合模塊,設計了一種對實驗所得數據進行曲線擬合的方法,對三種擬合方法進行了比較,曲線擬合結果表明,多項式擬合方法相對于其它兩種擬合方法效果更好;根據曲線擬合的結果可從帶激勵線圈的磁致伸縮換能器的輸入阻抗中分離出磁致伸縮換能器鐵芯在無激勵電流時機械振動形成的等效輸入阻抗,並由此輸入阻抗確定了磁致伸縮換能器的諧振頻率及其電氣模擬網路參數;最後通過labview提供的網路功能,實現了基於web服務器的磁致伸縮換能器電氣模擬虛擬儀器測試系統,並探討了通過datasocket技術實現該系統網路化的方案。Standard practice for combustible gases in the gas space of electrical apparatus using portable meters

船用電氣儀表環境試驗的通用規則Electrical and pneumatic analogue chart recorders for use in industrial process control systems - guidance for inspection and routine testing
工業過程式控制制系統用電動和氣動模似圖表記錄儀.檢查和常規試驗指南Electrical and pneumatic analogue chart recorders for use in industrial process control systems - part 2 : guidance for inspection and routine testing
工業過程式控制制系統用電動和氣動模擬圖表記錄儀.第2部分:檢查和常規試驗指南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分享友人
