英文摘要：

To achieve precision forming of beating outer ring for high-speed rail, the simulation model of the cold rolling process for high-speed rail bearing outer ring was established by using ABAQUS finite element software based on the basic theory of cold rolling. And the cold rolling process was numerically simulated. The evolution of stress and strain fields in the rolling process was analyzed. Its deformation mechanism was expounded. Study results lay the theoretical foundation for the realization and promotion of cold rolling roll forming technology for high-speed rail bearing.
