The object of research is the process of contact interaction, friction and wear of the working surfaces of machine parts. The purpose of scientific and research work is the development and implementation of the theoretical basis of the calculation and testing for wear and use them to improve the wear resistance of the friction units. In conducting research in the project used an integrated system approach to the analysis of processes of friction and wear of the mathematical basis of the accepted theory of differential equations, calculus of variations. Use experimental methods for determining the tribological properties of oils, special test equipment to determine the properties of the surface layers. As a result of operation of the system is designed to test methods and calculations for wear patterns with variable section: sphere, cylinder, cone. The theoretical basis and the experimental test methods lubricated surfaces. The methods of numerical simulation of wear and reliability prediction of friction units wear the criterion for assessing the behavior of the friction units under real operating conditions. A new approach to the theory test methods for wear: the method of variable contact area when tested with the determination of the model parameters of wear. The resulting analytical model with the parameters of durability for a fundamentally new scheme of wear testing "cone-three ball" to assess the evaluation of the impact of technological and structural parameters for wear. Proposed components of the finite element stress analysis of the surface condition of tribo surfaces and a criterion for optimal wear resistance make up a minimum stress. Implementation of the project provides an opportunity to save material, energy and labor resources due to reductions in field tests and experimental research in the design of the friction units
