ABOUT THE NON-IDENTITY OF THE TECHNOLOGICAL IMPACT UPON ITS REPEAT REALIZATION IN THE CASE OF SURFACE PLASTIC DEFORMATION (SPD)

Grigorov V. I.

pg(s) 3-5

Achieving the appropriate characteristics of treated surfaces by SPD is not only entails with choose of relevant scheme solutions, deforming elements, regimes and conditions of processing, but also with the specifics of the re-implementation of the technological impact. It is reasonable to assume that re-implementation of the technological impact is identical to its previous implementation, if with that is achieved only generates additional smoothing effect due to the increased multiplicity of the metal deformation in the same area of the treated surface.

CFD MODELING OF TURBINE FLOW METERS

pg(s) 6-8

Computational fluid dynamics (cfd) techniques provide investigations in conditions where the real experiment can’t be fulfilled for some reason, so these tools have found their applications in many spheres of science and technology; in particular they are widely used in flow metering.

Some of CFD applications we would like to propose and discuss in this work in the context of turbine flow meters. We discover non-drag type of turbine flow meters to check if created design with hydro-dynamic bearings should provide really floating rotor. For this purpose only numerical research can solve verification problem with minimal costs and simple realisation.

CFD models are used to examine pressure contours and velocity profiles near floating rotor in turbine flow meters. A full three-dimensional flow simulation of realistic meter configurations has been carried out. Close attention was paid to simulation of the complete geometry of turbine meters including front-end and tail-end shapes of flow conditioner hub, metering cells, etc. Some advices to meters’ designing were given.

OPTIONS FOR SYNCHRONIZING BUNKER DEVICES OF DIFFERENT TYPES, FLEXIBLE SUPPLY ASSEMBLY CENTRES

Shopov I.

pg(s) 13-15

An important trend in the development of tools for the automation of assembly processes is a study of the principles and relationships to design the assembly centres. Since in the assembly centres concentration and combining different assembly operations are used it is necessary hopper feeders with different principle of action ( as vibration and mechanical ) to operate synchronously. The task is placed and a solution to the problem of synchronization of vibration bunker feeder (BF) and mechanical (Gate) feeder was found.

PROCESSING OF THE GROOVES THROUGH SURFACE PLASTIC DEFORMATION

pg(s) 16-18

The processing of the grooves for a putting gaskets in the hydraulic holes is embarrassed because the high requirements for their precision and roughness. In this case like a method for finish processing it is suitable using surface plastic deformation. This method ensures as the quality of the machining surface as higher productivity.

COMBINED TOOLS FOR SURFACE PLASTIC DEFORMATION WITH RADIAL FEED

Kostadinov St.

pg(s) 19-21

Like a method for a finishing processing, the surface plastic deformation improves the exploitation characteristics of the ma-chining surfaces and increases their qualities. Moreover – it achieves sizable decrease of the machining times in comparison with the other finishing methods. The using of combined tools creates circumstances for simultaneously processing with the prior machining, which leads to augmentation of the machining productivity.

ПРОУЧВАНЕ И ПРОЕКТИРАНЕ НА ПРОИЗВОДСТВЕНАТА ИНФРАСТРУКТУРА

Ениманев Кр. Ив.

pg(s) 26-28

Besides the project preparation for sites of production infrastructure and their endorsement, the assessment of such projects on the base of transaction costs is quite necessary and useful as well. So the stage of development of the pro-duction infrastructure and the needs of a particular region to be defined, a huge significance is given to the transaction costs made, since they allow the relation between the economic participants to be estimated.

Рачев Д. Ст.

pg(s) 29-31

This article is related about contemporary concepts applied in automation machinery’s design and its ability to be implemented in production process. In this direction meaning of automation has been expanded, a new concepts and connections have been defined. Entire technical equipment in automation system is defined, and arise the chance for widening of this process.

There are a few examples of author’s design and implementation of automation machinery and how they participate in the system “automation”

ОТНОСНО КОРАВИНАТА НА ПОДВИЖЕН ДВУНОЖОВ БЛОК С ОСОВО РАЗМЕСТЕНИ РЕЖЕЩИ ПЛАСТИНИ

pg(s) 32-35

The floating blocks with two cutting tools having cutting inserts placed opposite to one another are used when turning inner and outer long cylindrical surfaces. The article presents a theoretical research of the influence of the axial displacement of the cutting inserts and the stability of the floating block on precision of machining with variation of the depth of insertion. Obtained are dependencies for quantitative assessment of this influence as well as conditions for reducing it.

ОЦЕНКА НА УСТОЙЧИВОСТТА НА ЖИЗНЕНИЯ ЦИКЪЛ НА ИНОВАЦИОНЕН ПРОДУКТ

Касабаджакова Ст.

pg(s) 36-37

This article has been viewed assess sustainability in the international agenda, which is a driving force for the industry’s international competitiveness. Sustainability comprises three pillars: environment, society and economy. For the environmental dimension of sustainable development, life cycle assessment (LCA) has been practiced for some time and standardized method. The other two pillars are further explored and defined. This article focuses on the level of product – rebuilt generator in discrete manufacturing.

ИНОВАЦИОНЕН ПОДХОД И МОДЕЛИ ЗА УПРАВЛЕНИЕ НА ЕМОЦИОНАЛНАТА И СОЦИАЛНА ИНТЕЛИГЕНТНОСТ

Костадинова И. В.

Представени са три концептуални модели, всеки от които може да бъде използван като инструмент за оценка и управление на човешката резултативност и успех в живота. За целта на бъдещата емпирична работа, свързана с оценяване икономическата, социалната и терапевтична резултативност на лекарския труд, авторът обосновава изборът на смесения модел за управление на емоционалната и социална интелигентност на Даниел Голман и предлаганите от него оценъчни инструменти. Конкретните задачи, които са изпълнени в изложението са: анализ на концептуални модели за ролята на емоционалната и социална интелигентност; избор на инструментален апарат за оценка на тяхното влияние върху професионалните умения и компетенции; съставяне на принципен адаптиран модел за повишаване на резултативността на труда чрез определяне на универсални лични и професионални компетенции с отчитане влиянието на емоционалната и социална интелигентност.
