Abstract : the responses of shaft bow and their relationships with unbalanceresponses and mechanical or electronic run out are analyzed based on the theory of rotor dynamics. the responses of shaft bow are separated from the unbalance responses successfully by making use of vibration information under different rotor runs. an identification method of thermal bend is presented based on the 2d - holospectrum technique. experimental results show that when bow phase is steady and amplitude is variable, the tangent of initial phase point on the 2d - holospectrum is parallel, which can be effectively used for diagnosis of bent shaft
文摘:依據轉子動力學理論分析了柔性轉子彎曲響應的特徵,在此基礎上討論了它與不平衡響應及機械與電氣跳動量之間的關系,並利用轉子在不同起車情況下的振動信息,有效地分離了彎曲響應和不平衡響應,求解出彎曲量與不平衡量的比值.提出了轉子在恆定轉速下,基於二維全息譜技術的熱彎曲故障識別方法.研究結果表明,當彎曲量相位穩定而其幅值變化時,轉子響應的二維全息譜初相點的切線是相互平行的,由此可以有效地實現轉子熱彎曲故障的識別與診斷( 3 ). the flattening arithmetic of an edfa was presented based on the inter - correlative function between the gain spectrum function of the edfa and that of the reserve transmission spectrum of the lpfg. for optimal matching between the two spectra, the flattening arithmetic calculates the variation of the resonant amplitude and wavelength of the lpfg
