Abstract

Roller/ring tribo-fatigue system which is used in wear-fatigue tests as the model of wheel/rail system is considered. In this system as well as in wheel/rail system stress-strain state is defined by interaction of contact and volume deformation of one of the system elements. These loads in the roller/ring system are defined by single compressive force. Results of finite element simulation of stress-strain state of roller/ring system are presented. Significant change of contact parameters and stresses distributions in this system due to the bending of the ring comparing to the contact pair is shown.

Keywords tribo-fatigue system, contact interaction, bending, roller/ring, wheel/rail, stress-deformed state, computer simulation
