Study on Vibration Characteristics
of Metro Bogie with Permanent Magnet
Synchronous Direct Drive Motor
Liqiang Yang, Xiaoping Jia, and Li Huang
Abstract In this paper, the vibration characteristics of a metro bogie directly driven
by a permanent magnet synchronous motor are introduced. In a field test, by arranging
acceleration sensors on the bogie and the car body to obtain the vibration signals of
the various parts of the vehicle, the vibration of the motor and axle box during
the operation of this type of bogie was acquired and analyzed, and the vibration
transmission of the bogie was mastered in detail. Through the time/frequency domain
analysis theory, the results demonstrate that the RMS of motor vibration acceleration
increases with the increase of vehicle speed, and the main frequency of the motor is
identical before and after the motor is removed. In addition, the traction rod seat has
6 characteristic frequencies, and each characteristic frequency exists at both root and
end, while the energy amplitude at the end is larger. It can provide a certain technical
reference for the application and further research of this bogie.

21.1 Introduction
Compared with three-phase AC asynchronous motor, permanent magnet
synchronous motor (PMSM) is more energy-saving, environment-friendly and has
better performance [1], it can effectively reduce the volume and weight of the traction
drive system, reduce the noise and improve the efficiency of the transmission system
