“…The results showed that different idempotent coefficients, materials and laws of materials affected the natural frequency of rotor systems [9]. Bouzidi et al (2020) analysed the dynamic characteristics of the functional gradient rotor-blade system using the finite element method, modelled the rotor-blade system using the Euler-Bernoulli beam theory, and finally discussed the effect of power-law distribution on the inherent frequency of the rotor-blade system.…”

In the fast-increasing speed of EMUs (Electric Multiple Units), the stability, reliability and smoothness of the EMUs in operation are guaranteed by exploring the rotor vibration model of the traction motor equipment of the EMUs. The finite element model of the rotor is constructed using the finite element algorithm, and the rotor model is used to simulate the rotor of the traction motor according to the radial vibration. The influence of factor changes on the vibration characteristics of the rotor system is discussed. Finally, the radial vibration effect on the rotor under the influence of various factors is explored through simulation. The results show that in the bending mode analysis of the rotor system, the rotor presents four bending modes; in the analysis of the influence factors of the radial vibration of the rotor system, the angle of unbalanced magnetic pull, the angle of rotor gravity, and the angle of rotor bending stiffness are compared. The analysis of the influence of the radial vibration of the rotor shows that the unbalanced magnetic tension increases the amplitude of the rotor and reduces the natural frequency of the radial vibration of the rotor system. The radial dimension of the axis track and the displacement spectrum has no significant difference with or without gravity. When the position of the axis track is relatively static, the offset distance of the rotor centre decreases with the increase of stiffness. When the rotation frequency component is 0.8k0, the amplitude is the largest; in the bending-torsion coupling analysis, the largest amplitude is the torsional vibration of the external torque frequency of the excitation, around 840. Therefore, it is found that radial load leads to torsional vibration of multiple frequencies in the torsional vibration of the rotor, and torsional load also causes bending torsional vibration of multiple frequencies in the torsional vibration of the rotor, which provides a reference for later vibration analysis of the rotor in the traction motor of EMU.
