由於機械運轉速度的不斷提高和新型材料、新型結構的推廣應用，旋轉機械的非線性動力學行為日顯突出和重要.基於線性系統原理的轉子動力學理論與方法難以對實踐中出現的豐富的非線性動力學現象作出準確的描述、闡釋和預測.近年來，隨著非線性科學研究的深入和滲透，轉子系統非線性振動已成為應用力學和機械工程領域的研究熱點之一.從有利於建立旋轉機械振動狀態集與故障集之間的映射關系出發，綜述了近年來轉子系統非線性振動研究的主要進展，總結了轉子系統中出現的典型非線性動力現象及其產生機理，目的在於豐富旋轉機械故障診斷知識庫.參55Abstract : 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When the mosquitoes in flight come into contact with the chemical droplets floating in the air, they will be killed. however, its ability to penetrate dense foliage or obstacles is not as good as that of the thermal fogging
