P. 1071–1196.Defects of crankshaft friction surface treatment,which reduce their wear resistance, are analyzed.The technology of processing of friction surfaces of a shaft and babbitt sliding bearings which increases their geometrical accuracy and wear resistance and reduces coefficient of friction is developed and investigated. The essence of the main technology in the grinding and penetration of diamond grains based on disulfide-molybdenum oil in the surface during their friction and compression. The absence of surface wear for a long time of operation of the crankshaft has been experimentally confirmed

No full textThe paper is devoted to the problem of searching the optimal parameters of time sampling of random stationary processes. Based on the analysis of existing approaches to this problem, the author suggests the approach developed by S. V. Dotsenko. This approach was applied for determining the optimal parameters of time sampling for the process, reflecting the change of carbon oxide content in exhaust gases of internal combustion engine. The algorithm for calculating the optimal parameters of time sampling was developed. Using the graphical environment of simulation modeling Simulink, the models of analog-digital and digital-analog converters are constructed. Simulation was carried out taking into account the optimal parameters obtained by the method, proposed by S. Dotsenko, and using the Nyquist sampling theorem. Based on the obtained results of relative errors of digital conversion, conclusions on advantages of the method, chosen by the author, were made.Данная статья посвящена проблеме поиска оптимальных параметров временной дискретизации случайных стационарных процессов.
