Vibration signal was gained through the vibrate testing of rotating model and steam - electric generating set 對旋轉(zhuǎn)機械模型和汽輪發(fā)電機組分別進行了振動測試,獲取了振動信號。
With general dimension series single value approach and general dimension most correlation coefficient method brought forward in this paper , fault classification and identification and diagnosis of rotating model system were checked , and favorable results were obtained 得到較準(zhǔn)確的結(jié)果。并將此方法應(yīng)用于汽輪發(fā)電機組中的復(fù)雜故障的診斷、識別及分類,都收到了良好的結(jié)果。
In this paper , it has been studied based on the fractal theory , multi - fractal theory , calculation and analysis of each fractal dimension and general dimension being set as fault feature that fault diagnosis and identification of rotating model and steam - electric generating set 本文基于分形理論、多重分形理論,通過對各分形維數(shù)的計算分析,把廣義分形維數(shù)作為故障特征量,對旋轉(zhuǎn)機械模型及汽輪發(fā)電機組的故障診斷與識別進行了研究。
