As an important parameter of the vehicle, the relationship between the tread equivalent conicity and the vibration of bogie for EMU is very valuable and significant for research. In this paper, a tracking test is carried out on the EMU running on a certain line to analyze the equivalent conicity and frame vibration of the vehicle. The evolution law of the equivalent conicity and the relationship between frame vibration and repair cycle and operating mileage during the tracking test of the vehicle are obtained, which provides a certain foundation for deepening the basic theory of high-speed rail and the technical research of high-speed rail with a speed of 400 kilometers in time.
