Diagnosing the Vibration State of the Rotors of a Double-Flow Turbojet Engine Using Phase-Frequency Characteristics Obtained without Using a Shaft Position Sensor
Tóm tắt
Theoretical and practical approaches to constructing phase-frequency characteristics of a double-flow turbojet engine (TJE) are considered and the results of experiments are presented. The novelty of this work lies in the use of the vibration phase to diagnose the technical condition of the turbojet engine rotors and in the elimination of the use of information from the sensor of engine’s initial position for constructing the phase-frequency characteristics of the rotors. The method of orbital vibration analysis is used to determine the instantaneous value of the rotor oscillation phase. The use of the analysis of changes in the phase of vibrations makes it possible to determine the presence of resonance processes, as well as defects and malfunctions that cause changes in the parameters of stiffness and damping of the rotor. Examples of diagnosing a turbojet engine using the analysis of phase-frequency characteristics are given.
