Summary:Abstract In this paper, a dynamics test is carried out on the 120km/h type A metro vehicle, and the vibration characteristics of the car body, the bogie frame, the motor and the gearbox are respectively monitored at different speed levels of the motor car and trailer. Vibration acceleration sampling was conducted according to GB/T 5599-2019 to obtain the vehicle body’s stability index and analyze the vehicle body’s vibration characteristics. According to UIC518-2005, the root mean square (RMS) value of the frame lateral acceleration is used as an index to analyze the vibration characteristics of the frame. By sampling and analyzing the vibration acceleration of the motor and gear box, the rotation frequency of the motor at 95km/h and the vibration transmission frequency of the transmission system in three directions are obtained.
