A Parameter-Driven Methodology of Wheel Flat Modeling for Wheel–Rail Impact Dynamics

A wheel flat is a typical wheel defect that significantly impacts the wheel–rail system, posing substantial challenges to vehicle operation safety. In the existing literature, the wheel flat plane model does not account for the contribution of the width direction to the impact response and thus cann...
