ABSTRACTS

Bishutin S.G., Tulpinova N.V. Forecasting of heat separation in contact zone of stock and abrasive disk with taking in account its wear process. The original methodology of forecasting of heat separation during grinding of the constructional materials with taking into account change of state of working surface of abrasive tool during its usage is present.

Gorlenko A.O., Matlakhov V.P. Maintenance of wear resistance of surfaces of friction by controlled technological action. In given article the model of contact interaction and wear pro-cess of cylindrical surfaces is considered in view of a roughness, a sinuosity, macrodeviations and physicomechanical properties of a superficial layer. According to kinetic model of wear process parameters of quality of the superficial layer, controlled with the help of various technological methods are chosen. Possibilities of technological methods of direction in these parameters are considered.

Erohin V. V. Maintenance of parameters of quality surfaces of adaptations for machine tool. In clause substantive provisions on maintenance of parameters of quality of functional sur-faces of details adaptations depending on their set of operational properties and are stated to de-manded accuracy of installation of preparation in the adaptation.

Shatov A.J., Boikov D.A., Stupak A.A. Linear shrinkage steel casting, its communication with the diagram of a condition. In work alculations of stage-by-stage measurement of the linear sizes steel casting are carried out. Influence peretective transformations is revealed on sizes beforperlitive and full linear shrinkage. The comparative estimation of the re-ceived settlement results with experimental data is carried out.

Shec S.P. Increasing of cuff proofing capacity by combining with magnetic fluid seal. Dif-ferent modes of operation are considered. The bases of the calculation on hermetic of cuff seal acting in combinations with sealing-lubricating magnetic liquid are presented. The defects in the work of separately installed cuff of the seal are revealed and the possibility of their compensation by unique characteristics of sealing-lubricating magnetic liquid is presented.

Davidov S. V., Keshenkova V.G. Modern structural materials for turbo blade row. The main groups of modern structural materials of turbo blade row are described and their structural stability is estimated

Mikhalchenko G.S., Yurshin A.S. Estimation of wearing the wheels of freis locomotive with radial steering design of bogies. Analysis of dependence of work of friction forces in the con-tact between wheels and rail on tractive force, vehicle velocity, curve radius and cant considered. Impact analysis of wearing the wheels of freight locomotive with traditional and radial steering design of bogies is given.

Pakhomov Y.A., Rogalev V.V. 50 years anniversary of the Internal combustion engines speciality in Bryansk state technical university. The article views the stages of formation and development of educational and scientific basis of the internal combustion engines speciality, its contribution to preparation of high qualified specialists for engine engineering. Fundamental sci-entific achievements and future researches directions are reflected.

Buglaev V.T., Kartashov A.L., Perevezentsev V.T. Increase of reliability and profitability of steam turbines with use cellular condensation. Modernization of sealing in a flowing part of steam turbines is offered due to application of cellular sealing with optimum ratio of cells. The way of sealing repair on a shaft of the turbine and, ending sealing of turbines for nuclear power plants is examined.

Kazakov V.S., Klimenko T.V. Diagnostic vibroacoustic performances of designed engine installations. The article considers the modern methods of estimating the performances of tech-nological noise and vibration from power equipment, it also carries out calculating, diagnosing and rationing the level of the noise generated by a compressor station at the stage of designing.

Gulakov K.V., Gulakov V. K. Techniques of improving performance of OLTP-systems based on Microsoft SQL Server 2000. The purpose of this article is to provide helpful infor-mation on how to improve Microsoft SQL Server's performance.

Kochenkova N.I. The problem of introduction of ideology Lean on the Russian manufac-tures. The ideology of manufacture lost-free, the so-called economical manufacture, known as Lean Production, with reference to the Russian conditions is considered.

Korsakova I.M., Govorov I.V. Economic aspects of modernization of the equipment. The are considered the possible ways of industrial equipment improvement by the example of the test bed intended for check of geometrical accuracy of track measurement carriages. Calculations of comparative efficiency of work on manufacturing and operating appropriate test bed modifica-tions are carried out.

Zolin I. E. Labour Market under Globalization of the World Economy: Problems of Theory and Practice. This article analyses the existing situation on the labour maket under globalization of world economy; defines the major current methodologic problems of labour market / international labour migration research; presents the principle directions of the authorities activi-ties to regulate the migration processes along with the mechanisms of their realization.

Afonina E.V. Some aspects of teaching of graphic-geometrical disciplines at modern tech-nical university. Separate aspects of teaching of graphic-geometrical disciplines at modern technical university are considered. Some recommendations on improvement of quality of prepa-ration of experts and perfection of teaching of disciplines of an engineering-graphic cycle on the basis of an operational experience of faculty Descriptive geometry and the schedule are re-sulted.
