Abstract

Abstract

To investigate the bending-torsional vibration mechanism of EMU traction motor rotor and identify their typical fault features under the action of combined loads, the rotor structure was lumped into a rigid-disk-massless-shaft system according to the actual structure configuration of EMU traction motor, and a bending-torsional mechanical model of motor rotor system with ten degrees of freedom was established. The differential equation of bending-torsional coupling motion of traction motor rotor system was built by using Lagrange's equation method under the action of multiple radial and torsional loads, such as the unbalanced magnetic pull caused by the static and dynamic air-gap eccentricity, the mechanical unbalanced force caused by the mass eccentricity, the rotor gravity, the driving torque and the load torque of motor. The bending-torsional vibration characteristics of rotor system under different combined load cases were calculated and analyzed based on the Runge-Kutta method. Analysis result shows that the coupling relationship of bending and torsional degrees of freedom caused by the mass eccentricity of rotor makes the bending and torsional vibration characteristics of traction motor rotor system affected mutually by the radial and torsional loads of rotor, and the influence results conform to the law induced by the mass eccentricity coupling of rotor.Under the action of all radial and torsional loads, the radial vibration of traction motor rotor includes the frequency components such as the zero frequency, the rotation frequency, the double rotation frequency, the bending natural frequency, the double power frequency and its combinations with rotation frequency, the combination of pulsating torque frequency and rotation frequency, and so on, and among them the bending vibration amplitude corresponding to the rotation frequency component is the largest, while the vibration amplitude of the combination of pulsating torque frequency and rotation frequency is very small, which means that the contribution of pulsating torque to the radial vibration of traction motor rotor is not obvious. The torsional vibration of traction motor rotor under the action of all loads consists of the frequency components such as the rotation frequency, the double rotation frequency, the combination of bending natural frequency and rotation frequency, the combination of double power frequency and rotation frequency, and the pulsating torque frequency, and so on, and among them the torsional vibration amplitude corresponding to the pulsating torque frequency is the largest, and the torsional vibration amplitude corresponding to the rotation frequency caused by the gravity and unbalanced magnetic pull is also larger, and both them basically have the same order of magnitude, which means that their contributions to the torsional vibration cannot be ignored.
