Investigation of Stress State and Contact Pressures in Contact Area of Journal Bearing by Numerical Simulation

Goal of the paper was to investigate stress state and contact pressures in contact pair of tribological assembly by numerical simulation. This paper deals with simulation of cylindrical contact pair. One part has convex (shaft) and other one concave (hole) surface of the body. This assembly represents friction state of the plain cylindrical journal bearing. The paper includes results of stress state and contact pressures from two loading states. The first loading state includes only radial loading without effect of the torque moment and the second one includes radial loading with torque moment. If we want to know more about tribological processes we will have to know stress state in the materials loaded through contact interaction between two bodies to the last detail. This level of knowledge can be achieved just by numerical simulation. The simulation was made by CAE system ANSYS.
