本文应用幅频特性曲线模态计算法[2]实测转子—支承系统在盘处的偏心距与阻尼比,并测定盘处挠度,应用传递矩阵法[1]计算了该转子的有阻稳态不平衡响应,计算结果与实验吻合较好,本文还研究了阻尼等因素对挠度及轴承受力的影响。本文所采用的实验研究方法及结论可供工程设计及实验研究参考。 In this paper, the modal calculation method of amplitude-frequency characteristic curve [2] was used to measure the eccentricity and damping ratio of the rotor-support system at the plate, and the deflection at the plate was measured. The steady state of the rotor was calculated by the transfer matrix method [1] Unbalanced response, the calculated results are in good agreement with the experimental results. In addition, the influence of damping and other factors on the deflection and bearing force is studied. The experimental research methods and conclusions adopted in this paper are available for engineering design and experimental research.
