AN INVESTIGATION INTO THE FIELD IDENTIFICATION TECHNIQUE OF MODAL PARAMETERS OF ROTATING SYSTEM

  • 哈尔滨工业大学

    Graphical Abstract
    • 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.
