| 摘 要： | 针对回转机械常用信号处理方法的４个缺陷，提出了基于改进傅里叶变换的瞬态提纯轴心轨迹方法，淫来分析瞬变信号，该方法集成了短时傅里叶变换和全息谱的优点，通过一系列工频椭圆的变化规律来直观地反映转子的振动特性。经启车实例分析，证明该方法将成为诊断和分析转子振动特性的强有力工具。

| Abstract: | Nonstationary vibration is analyzed by application of instantaneous orbit and improved Fourier transform, in addition to short Fourier transform and regular holospectrum. The method could reflect the vibration characteristics of rotor systems based on analysis corresponding frequency ellipse. Transient vibration during the start up stage is studied as examples. |
