SUMMARY MECHANICAL ENGINEERING УДК 621.01.001 Effectiveness of devices application with calculated parameters / V. V. Mikityansky, L. M. Mikityanskaya // Astr. <...> For the first time there was formulated the problem about the role of machine devices in the capacity of technological operations of mechanical treatment. <...> The influence of application of machine devices with design parameters was demonstrated on the capacity of technological operations based on the developed procedure of research of devices dynamics. <...> The authors introduced a new coefficient of intensity of technological processes as a result of application of designed devices. <...> Designed technique of technological processes capacity in mechanical engineering is given as a result of application with known dynamic parameters. <...> УДК 621.9.047 Surface quality and properties of machinery parts / A. A. Aliev, V. P. Bulgakov, B. S. Prikhodko // Astr. <...> It is noted that roughness has an effect on metal corrosion as well as corrosive cracking, fracture fatigue and tightness. <...> УДК 621.837.001.57:531.3 Approximation of work load function of executive press mechanism with circular sections / T. O. Nevenchannaya, A. Y. Mitin, E. V. Ponomaryova // Astr. <...> When solving the problems of defining the dynamic parameters of mechanisms special attention’s given to the load defining acting their elements. <...> The given approach for making up the model of diagramme of load on cross head of crank mechanism allow to investigate the dynamics of the system in view of its work features. <...> УДК 621.753.4 Putting a problem of investigation of dynamics influence of machine tool devices on dynamic perform and data of the whole technological system / P. N. Zaripov // Astr. <...> The role of fitting and machine tool devices is shown as well as their influence of their dynamic characteristics of the whole system. <...> Urgency and long-term introduction of systems of automatic designing as well as their devices were analysed in mechanical engineering. <...> It was determined that the precision of devices used for mechanical treatment is one of the main factor and it offers great opportunity for precision and interchangeability of made parts. <...> Complete design of mechanical system with determination of such dynamic parameters as stiffness, elasticity, actual frequence of vibrations, etc. are made with obvious errors as the result of application of different empirical connections and coefficients. <...> It <...>
