AN INVESTIGATION INTO THE FIELD IDENTIFICATION TECHNIQUE OF MODAL PARAMETERS OF ROTATING SYSTEM
-
摘要: 基于时域振动参数识别理论,本文讨论了由转子和油膜轴承构成的转子系统的模态参数现场识别问题。本文所述方法不需要施加人工激振,仅在轴承座处测量轴承座的振动和转子的绝对振动,可以在线应用。Abstract: Based on the time-domain vibrating parameter identification theory, the field identification technique of modal parameters or rotating system composed of oil-film bearings and rotor is investigated in the present paper. The method proposed by this paper does not need artifical excitation force and oniy needs the vibration signal of bearings and neck journals. This method can be applied on-line.
