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:依据转子动力学理论分析了柔性转子弯曲响应的特征，在此基础上讨论了它与不平衡响应及机械与电气跳动量之间的关系，并利用转子在不同起车情况下的振动信息，有效地分离了弯曲响应和不平衡响应，求解出弯曲量与不平衡量的比值.提出了转子在恒定转速下，基于二维全息谱技术的热弯曲故障识别方法.研究结果表明，当弯曲量相位稳定而其幅值变化时，转子响应的二维全息谱初相点的切线是相互平行的，由此可以有效地实现转子热弯曲故障的识别与诊断
