Abstract

Through the track mode calculation theory, it is found that the resonance with the 3rd order mode of the track is the main reason for the formation of the 20th order wheel polygon, and the theory is verified by experiments. Finally, the anti-resonance wheel polygon wear suppression measures are proposed, including changing the support damping of the rail, optimizing the structure of the wheelset and bogie frame to avoid the 580 Hz high-frequency resonance. The existing polygon wear can be avoided by changing the vehicle operation speed and operation line.
