Abstract
Technological progress is impossible without new innovative developments, discoveries, inventions. Modern nonlinear technical systems cannot do without the use of friction units, which are various gears, connections, as well as complex nodes and devices. The geometrical parameters of the railway-rolling stock system were optimized when moving in curves of small radius. A unique roller rig was used to carry out model tests using the method of physical and mathematical modeling. It is proposed a method for increasing the efficiency of friction systems, which is based on fundamental research in the field of mechanics of contact friction interaction of solids. One of the technical solutions implemented on the basis of this study is the development of technology and technological equipment for increasing the traction force of a locomotive and increasing the service life of wheelsets. The theoretical basis of this technology is the anisotropy of friction junctions formed by thermos metal plating of the wheel working surfaces.
