Abstract : The two-dimensional thermal effect of sliding frictional contact of material thermal stresses is investigated in this paper. Products and machinery with moving components nearly always include parts which experience frictional forces. Often, only the structural contributions to the stresses and deformation of the parts are analyzed. Frictional heating, however, creates a conduction thermal gradient along the parts, which adds to the overall stresses and deformation. Models have been developed to analyze the thermal gradients due to frictional heating for simple geometry1. We intend to develop a frictional contact model which accounts for both the structural and thermal effects on stresses and deformation of our geometry and will verify our model through a combination of linear thermal elasticity and a simplified analytical thermal conduction analysis. The purpose of this complex model is to give a more realistic simulation of the contact surface. This paper will take an in-depth look at how the frictional heat generation is incorporated into commercial solver ANSYS and compare this to an analytical solution. To accomplish this task simple practical model of frictional problem will be used for both the ANSYS simulation and the analytical solution. To aid in verification of the two solutions, a loosely coupled MATLAB code will be used on the same geometry with reasonable approximations. With this verification we hope to show how to implement frictional heating in other model, and whether it is even important to account for the frictional heating. Keywords- Frictional Heat Partitioning, Boundary Layer, Sticking Contact, Hot Spots.
