ABSTRACT

A contact of machinery real engineering surfaces has a complex geometry and is defined by errors at machining, in particular, by macrodeviations, corrugation and roughness. This paper report the consideration carried out on a fluid consumption through an end axisymmetric sealing arrangement formed by a joint of metal surfaces. Sealed environment consumption is defined through a sum of leaks through a slit between surfaces conditioned on corrugation and dripping through a porous layer farmed by surface roughness on contact contour spots. The surface corrugation is modeled by splines according to initial parameters of a corrugation, and as a roughness a surface fractal model is used repeating a real roughness most accurate. On algorithms presented taking into account basic parameters of corrugation and roughness the 3D models of engineering surfaces are created and after their bringing in contact arises a possibility to obtain practically all parameters of contacting defining the impermeability of a sealing arrangement. The application of 3D models allows rendering processes passing in a contact of conjugate surfaces and obtaining some data, for instance, a tortuosity of leaking channels which earlier were chosen according to recommendations which no doubt increases computation accuracy.

Editor-in-chief of the journal Bulletin of Bryansk State Technical University KHANDOZHKO ALEKSANDER VLADIMIROVICH Aleksander Vladimirovich Khandozhko is Doctor of Engineering (2002), Associate Professor (1993), Honorary Worker of Higher Professional Education of the Russian Federation, Professor of the Department of Metal-cutting Machines and Tools at Bryansk State Technical University (BSTU). He was born in Chelyabinsk in 1958. In 1980 he graduated from Bryansk Institute of Transport Engineering (BITE) (now - Bryansk State Technical University, BSTU) with a degree in Mechanical Engineering Technology, Metal-cutting Machines and Tools. From 1980 to 1983, he worked as a manufacturing engineer at an industrial enterprise. From 1983 until now he has been working at Bryansk State Technical University, having started his career at the university as a training master. In 1985 he entered the full-time postgraduate course in BITE. In 1989 he defended the thesis for the degree of Candidate of Science in the Dissertation Council of Moscow State Aviation Technological Institute (MSATI) on the specialty Heat Engines of Aircrafts. After defending his thesis, he worked as an assistant and then as an associate professor of the department of Metal-cutting Machines and Tools at BITE. In 2000 he entered the post-doctoral program and in 2002 he defended his doctoral thesis on the specialty of Technology and Equipment of Mechanical and Physical-technical Processing. After defending his thesis, he worked as a professor of the department until 2009. In 2009 he was appointed the head of the department of Metal-cutting Machines and Tools at Bryansk State Technical University. In 2016 when the laboratory of wave deformation and combined hardening in additive and subtractive technologies was founded at BSTU, he became the head of the department of modular technological equipment, continuing his teaching work as a professor of the department of Metal-cutting Machines and Tools. Khandozhko A.V. is a member of the editorial board of the journal Science Intensive Technologies in Mechanical Engineering (Bryansk). Since 2002 he has been a member of dissertation councils of several universities; currently he is a member of three dissertation councils D999. 155. 03, D999.112.02 and D212.021.03 aa well as being the Deputy Chairman of Dissertation Council D999.155.03. Topics of scientific research 1. Fundamental theoretical and applied issues of designing cutting tools. 2. Theory and practice of designing and manufacturing process equipment, including for additive-subtractive processes. 3. Issues of mechanical processing of materials. 4. Problems of providing product quality in mechanical processing and additive processes.
