Abstract:
The paper presents a solution in the quadratures of the problem of determining the principal vector and the principal moment of frictional forces arising from plane motion relative to the rough plane of the area limited by a polygonal contour affected by a uniformly distributed normal pressure. Similar problems arise in the study of traction forces of railway wheel pairs, including the forces of elastic deformations in the contact patch area. The results of the article can be used for comparative evaluation of the tribological characteristics of experimentally obtained lubricants.
