AB  - U radu prikazan je algoritam koji omogućava primenu 3D štampe u projektovanju ili modifikaciji proizvoda. Aditivna proizvodnja , ili tehnologija 3D štampe, podrazumeva izradu proizvoda složene geometrije u relativno malim količinama. 3D štampa omogućuje realizaciju modela prema digitalnom prikazu, a njena primena je ogromna u različitim proizvodnim granama. Glavne prednosti 3D štampe su: ušteda energije, smanjenje otpada, smanjenje upotrebe većeg broja alata, kao i optimizacija dizajna. Tehnologija 3D štampe radi na principu dodavanja materijala u slojevima. Model se formira od slojeva rastopljenog materijala koji se odmah hladi i očvršćava. Polazni materijal za izradu modela je polilaktična kiselina (PLA). Na mehaničke karakteristike realizovanog modela od PLA utiču različite promenljive kao što su: prečnik brizgaljke, debljina definisanog sloja, procentualna vrednost ispune,geometrija ispune, veličina uzorka, brzina punjenja i temperatura proizvodnje. Cilj ovog rada je da se prikaže algoritam kao deo procedure i aktivnosti kontrole pri realizaciji različitih modela. Time se projektantu daje mogućnost da realizuje nov proizvod, ispravi greške na postojećem proizvodu i na kraju modifikuje proizvod prema zahterima krajnjih korisnika.

AB  - Iako 3D štampa verovatno neće preuzeti mnoge konvencionalne metode proizvodnje, 3D štampač može brzo da isporuči složeni dizajn sa velikom tačnošću. Međutim, aditivna proizvodnja takođe pokazuje određene slabosti. Ako karakteristike materijala nisu definisane, mogu se pojaviti problemi u realizaciji 3D modela. U našem radu je razmotreno osam uzoraka sa različitim vrednostima parametara: visina sloja, orijentacija ispune i gustina ispune. U softveru Ultimaker Cura postavlјeni su svi parametri uzorka, dok vizualizaciju dizajna uzorka vrši putanja mlaznica. Mikroskopski pregled strukture ispune pokazao je da postoje određene nepravilnosti u cilјu ispitivanja realizacije i orijentacije slojeva. U našoj analizi upotrebljena je polinalektična kiselina (PLA). Spolјni uticaji su takođe važni poput: mehaničko oštećenje, temperatura na vrhu mlaznice i brzine hlađenja materijala u okruženju. Sve to utiče na kvalitet. Mikroskopskom analizom pokušali su da se utvrde korelacije, problemi unutar strukture materijala, ali i da se daju preporuke za pobolјšanje realizacije modela.

AB  - Aditivna proizvodnja uključuje izradu proizvoda složene geometrije u relativno malim količinama, kao i izradu alata i kalupa za masovnu proizvodnju. Aditivnom proizovnjom realizuju se modeli prema digitalnom prikazu, a primena je ogromna u različitim industrijskim sektorima. U poređenju sa tradicionalnom proizvodnjom, glavni parametri u odabiru aditivne tehnologije su: ušteda energije, smanjenje otpada, smanjenje upotrebe većeg broja alata, kao i optimizacija dizajna. Aditivna proizvodnja ili tehnologija 3D štampe rade na principu dodavanja materijala u slojevima, tj. model se formira od slojeva rastopljenog materijala koji se odmah hladi i očvršćava. 3D štampa omogućava čestu i jednostavnu modifikaciju modela na zahtev kupca, a pre ulaska modela u samu proizvodnju. Ovo čini komunikaciju na relaciji proizvođač-kupac dosta jednostavnom. Polazni materijal za izradu modela je polilaktična kiselina (PLA). To je ekološki termoplastični poliester koji se prirodno razgrađuje u prirodi. Na mehaničke karakteristike realizovanog modela od PLA značajno utiču različite tehnološke promenljive kao što su: prečnik brizgaljke, debljina definisanog sloja, procentualna vrednost ispune, veličina uzorka koji se puni, brzina punjenja i temperatura proizvodnje. Cilj ovog rada je da se prikaže postupak realizacije kutije elektronike za malogabaritni transmiter pritiska na 3D štampaču. Time se projektantu daje mogućnost da ispravi postojeće greške, modifikuje proizvod prema zahterima krajnjih korisnika i na kraju daje polazna osnova za realizaciju prototipa novog proizvoda.
AB  - Additive manufacturing involves manufacturing of products with complex geometry in relatively small quantities, as well as the tools and molds manufacturing for mass production. With additive manufacturing, digital models are being realized and implementation is huge in various industrial sectors. Compared to traditional manufacturing, the main parameters in the choice of additive technology are: energy savings, waste reduction, reduced use of more tools and optimization of design. Additive manufacturing or 3D printing technology works on the principle of adding material in layers, i.e. the model is formed from layers of molten material that is immediately cooled and solidified. 3D printing allows to work with customers to solve design problems before embarking on a launch production. The starting material for the model is polyactic acid (PLA). It is an eco-friendly thermoplastic polyester, that breaks down naturally. The mechanical characteristics of the realized PLA model are significantly influenced by various technological variables, such as following: nozzle diameter, thickness of defined layer, percentage of fill,
sample size to be filled, filling rate and production temperature. The aim of this paper is to present the process of realization of an electronics enclosure for a compact pressure transmitter on a 3D printer. This gives the designer the possibility to correct existing errors, modify the product according to the wishes of the end users and finally provides a starting point for the prototype of new product.

AB  - The trend of wind turbine development has a special significance in the exploitation of renewable
energy sources. At higher altitudes, we have better wind energy utilization higher speed and
their conversion are achieved in the best possible use of wind turbines. The development of new technologies
opens space for a new generation of wind turbines with a 20MW rated power. In recent
years, various feasibility studies have shown that wind turbines with large rotor diameter and high
towers give positive shifts in the analysis of structural and aerodynamic parameters, with a focus on
reducing overall mass and damping vibrations due to the use of new materials. In this paper, the
evolution of high power wind turbines and an overview of the technological development of the basic
components of the turbine will be presented. Perspectives in the further development of wind turbines
with rated power above 20MW will be also considered.
AB  - Trend razvoja vetroturbina ima poseban značaj u eksploataciji obnovljivih izvora energije. Vetroturbine velikog prečnika rotora i visokih tornjeva sve se više razmatraju u istraživačkim i razvojnim centrima širom sveta. Upotrebom vetroturbina na većim visinama gde je brzina vetra znatno veća ostvaruje se mogućnost boljeg iskorišćenja ovog obnovljivog izvora energije. Razvoj novih tehnologija otvara mogućnost za novu generaciju vetroturbina snage preko 20 MW. U poslednjih nekoliko godina razne studije izvodljivosti su pokazale da koncept vetroturbine velikog prečnika rotora koji se nalazi na visokim tornju daje pozitivne rezultate sa aspekta analize strukturalnih i aerodinamičkih parametara. Posebna pažnja posvećena je smanjenju ukupne mase i prigušenju vibracija korišćenjem novih materijala. U ovom radu prezentovan je razvoj vetroturbina velike snage, dat je pregled tehnoloških mogućnosti u proizvodnji osnovnih komponenti kao i perspektiva za realizaciju vetroturbina snage preko 20 MW.

AB  - In order to investigate both static and dynamic characteristics of composite plates and validate a contemporary, non-invasive experimental technique a comparative experimental and numerical analysis was performed. Three, geometrically the same but different in ply orientation, carbon-epoxy laminates were tested in both healthy and damaged conditions. Damages were inflicted in a shape of horizontal crack. Experiments and numerical simulations were performed by digital image correlation (DIC) and finite element method (FEM), respectively. Obtained time-responses of the tested structures were fast Fourier transformed (FFT) to frequency domain for a clearer
understanding of natural frequencies and oscillation modes. Results are presented in tabular and graphical form. The overall correspondence of two sets of structural displacements is satisfactory. Some discrepancies might be contributed to the idealized geometry and restraint consideration. Also, due to the fast damping of higher tones, the errors in determining higher natural frequencies increase but still remain in 5 % range.

AB  - The increasing size of wind turbine blades leads to various flow phenomena which are
influenced by aerodynamic design of blade. Detailed information of flow separation and wake
development are important for wind turbine blade designers to optimize blade design. In order to
obtain detailed information on the flow field, CFD (computational fluid dynamics) modeling is
the topic in many research studies.
In this paper aerodynamic analysis of the reference DTU 10 MW HAWT rotor using finite
volume method was done. Numerical simulations are realized in a commercial software package
ANSYS FLUENT. Flow field is modeled by Reynolds Averaged Navier-Stokes (RANS)
equations using transition SST viscous model. The pressure-based SIMPLEC pressure-velocity
coupling and 2nd order spatial discretization schemes were used for calculation. Obtained
numerical results for mechanical power, power coefficient, thrust, thrust coefficient, pressure
coefficient and relative velocity contours at rated wind speed were considered. The results were
compared with the reference results and conclusions were derived.

AB  - In this paper, GAP analysis and 5S tool are applied in the case of realization of a compact pressure
transmitter. GAP analysis, combined with the 5S tool, can qualitatively indicate the critical points
in the manufacturing, assembly and quality control of a finished transmitter. Existing errors lead to
the appearance of possible risks in the realization of production processes, from the input of raw
materials to the assembly of the finished product. In order to eliminate the existing errors, the main
steps of the GAP analysis are described in detail. Guidelines are provided on how to improve the
workplace manufacturing process through certain improvements by applying all 5S elements.
According to the implemented action plan, the main causes of risk occurrence in the GAP analysis
were: human factor and processing technologies. The human factor was characterized by poor
control in the workplace (there is no discipline), poor training and incompetence of employees for
the given tasks. Processing technology involves obsolete machines, which can introduce deviations
of dimensions and tolerances from the prescribed values.

Zbog eliminacije postojećih grešaka, u radu su detaljno opisani glavni koraci GAP analize. Date su smernice kako da se unapredi proces proizvodnje na radnom mestu kroz određena poboljšanja primenom svih 5S elemenata.

AB  - Metal membranes are defined as thin steel circular plates. The metal membranes are widely used in the measurement technique and they are constantly loaded over the entire surface. In case that a membrane is loaded with uniform load over the entire surface. In case that the membrane is stiffened over the edge, then it is called a diaphragm. According to the making method membranes are divided into flat and corrugated. Corrugated membranes are used mainly in a low pressure area. Membranes are most commonly made of firm alloy austenitic steel. In this paper numerical and experimental analysis of a thin corrugated diaphragm 24 mm diameter is presented, with variable material thickness and variable corrugations geometry. Experimental tests are conducted on a corrugated stainless steel (AISI 316) diaphragm. Experimental results are compared with numerical results in ANSYS software package. A comparative analysis of the sinusoidal and toroidal diaphragms has shown that there is a higher sensitivity of the sinusoidal diaphragm, that is, if the thickness of the diaphragm increases, and their stiffness is increased. In general, for small pressure ranges from 10 mbar to 50 mbar, the sinusoidal diaphragms have a faster response. © 2018 The Authors.

AB  - Metal membranes are the thin circular plates. For transducers and pressure transmitters, it is
assumed that the membrane is loaded with uniform load over the entire surface. In case that the membrane is
rigid over the edge, then it is called a diaphragm. In general, the membranes are divided into flat and
corrugated. Corrugated diaphragms can resist much higher pressure than flat diaphragms and they are used
mainly in the low pressure area. In contact with various aggressive fluids, membranes are most commonly
made of high alloy austenitic steel, which have high corrosion resistance, have good spring properties and
they are stable at different temperatures. The deflection analyses of corrugated diaphragms are very important
in sensitivity of transducers/transmitters. The application of corrugated diaphragms gives possibility to control
sensitivity of thin diaphragms by geometrical parameters. In this paper numerical and experimental structural
analysis of a thin corrugated diaphragm 19 mm diameter, with variable material thickness and corrugation
number is presented. Experimental tests are conducted on a corrugated stainless steel (AISI 316) diaphragm.
The measured deflections are compared with numerical results in ANSYS software package. The results
showed small deviations between numerical and experimental data, which is very important for further
diaphragm application of measurement instruments.

potencijal za upotrebu energije vetra, a on je najveći u priobalnom delu. Ovim radom analizirana je
brzina vetra radi upotrebe vetroturbina u ruralnim oblastima Libije., Libya is a rich country with oil and natural gas which accounts for over 90% of the country's total electricity
production. However, renewable energy sources, such as wind energy, are increasingly being used. In Libya there is a
huge potential for the use of wind energy, which is largest in the coastal area. This paper analyzes wind velocity for the
use of wind turbines in the rural regions of Libya.",
