摘要：
In order to study the influence of different rail grinding treatments and the matching characteristics between different wheel-rail profiles on vibration characteristics of track structures, in the case of a domestic EMU train and CRTSⅢ ballastless track structure, a coupling dynamics model was built based on vehicle-ballastless track-subgrade coupling system dynamics and the co-simulation technology of UM and Ansys to analyze the influence of wheel-rail matching on the vibration characteristics of track structure at different speeds. The results show that the wheel-ail profile wear has a significant influence on the contact characteristics, which change from single point contact to multi-point contact, causing the increase of the equivalent taper and contact angle. At the same time, the wheel-rail profile wear has influence on vibration characteristics of track plate structure to varying degrees. By grinding the rail, the wheel-rail contact characteristics can be effectively improved, and the vibration displacement and peak acceleration of the track slab can be reduced, which provides guidance for further improvement of grinding target surface. © 2021, Department of Journal of the China Railway Society.
