Abstract

The influence of elastohydrodynamic (EHD)-lubrication on stress field in contact area of rolling and sliding mechanical elements is presented in this paper. Computational analysis is performed using the equivalent model of two contacting cylinders that have the same radii as are the curvature radii of contacting mechanical elements at any point of a real contact. The equivalent cylinders are subjected to normal and tangential tractions that are determined with the Hertz contact theory with consideration of additional external contact forces that arise from the EHD-lubrication conditions. The finite element method is used for numerical computations of the stress field
