Wheel-rail profile matching based on finite element method for Beijing metro

IOP Conference Series: Materials Science and Engineering, 2017
An instrument that measures wheel-rail appearance is used to measure the size of the wheel and rail in the section of the Baishiqiao South Station of Beijing Metro Line 6 to develop a finite element entity. Different working conditions such as axle load and traction are considered.

Research on Low-Frequency Swaying Mechanism of Metro Vehicles Based on Wheel-Rail Relationship

Shock and Vibration, 2020
For the worn state of the wheel, metro vehicles often suffer a serious carbody swaying issue, which causes the lateral stability of the vehicle to exceed the limit and affects the ride comfort.
