AB  - New demands placed on industry make it necessary to improve design, real-time monitoring and failure prediction methods for rolling bearings. This paper presents an approach for assessing how contact surface damage affects the vibration response of rolling bearings and how vibration-based monitoring shows the damage level of rolling element bearings. A new parameter named the damage factor is introduced to quantify the vibration response of rolling bearings. The analytical-numerical method for calculation of this parameter is developed based on nonlinear dynamics postulates. The developed method for damage factor calculation is tested on a particular type of radial deep groove ball bearing, and an experimental verification is performed, showing a maximum deviation of 7% in the results. The conclusions drawn from the obtained results and the potential contributions of the introduced parameters for rolling bearing design are discussed. The chosen polynomial function keeps deviations in relation to the calculated damage factor within 3% for failed areas of different sizes.

AB  - Contact stress and deformations in the thrust ball bearing with a contact angle of 90 ° are 
 onsidered in this paper. Ideally, an external axial load of this kind of bearings should be centric, but in reality, this force may act eccentrically. As a result, the load distribution between balls is inequal. The most unfavourable case is when the axial force intersects the radius vector of one of the balls. The load, contact stress and contact deformation of this ball are greater than the load of all rest of the balls and greater in the case of equal load distribution. It limits the load-carrying capacity of a real bearing, compared to the theoretical static load rating. Analyzes have shown that considered thrust ball bearings do not lose operational ability at low speeds, even if there is some load eccentricity when an external axial load is not more than 30- 40% of static bearing capacity. Otherwise, additional bearing capacity analyzes are required.

AB  - Potrebno je odgovarajuće podmazivanje kotrljajućeg ležaja kako bi se smanjilo trenje između površina u međusobnom kontaktu i njihovo habanje.

A lubricant should completely separate the rolling elements from the raceways. The values that affect the efficiency and regimes of lubrication are analyzed in the paper, after which it is introduced a lubrication regime coefficient. This coefficient makes it possible to choose in a simple and fast manner an optimum combination of rolling bearing and lubricant based on the known shaft speed, external load, and rolling bearing operating temperature.

AB  - The influence of the running-in process operating parameters on tribological properties of the block-on-disc samples in lubricated sliding conditions is analyzed and discussed in detail. Different running-in regimes are achieved by varying the normal load and sliding speed. After the running-in period, during which the operating parameters are varied, all samples are placed in a working regime under the same set of operating conditions. At the end of the running-in period, as well as at the end of the working period, an analysis of the changes in the surface roughness, microhardness, wear rate, and coefficient of friction is performed. Less desirable properties in terms of wear rate and steady-state coefficient of friction are noticed for the samples that were run-in with the operating conditions which were the same as the working regime operating conditions. In the defined test conditions, it is shown that the intensity of normal load applied during the running-in process has a dominant influence on the amount of wear and coefficient of friction value. It was also shown that the running-in process can significantly improve the roughness of the initially rough contact surfaces. The results of experimental testing indicate that the variation of the operating parameters during the running-in process can be used to improve the working ability of the sliding contact surfaces under the mixed lubrication regime.

AB  - A new model of automation of technological systems, based on the Internet, was defined as the concept of Industry 4.0, Germany in 2011. It represents an advanced model of connecting machines and computers (cyber-physical systems - CPS), their networking (cloud computing and Internet of Things (IoT)) with the widespread use of advanced artificial intelligence (AI) in this concept. This concept is a model of smart manufacturing (SM), and today we are talking about: smart vehicles, smart highways, smart grids, smart cities, smart services, etc ... - in short, intelligent "everything and anything" (smart everything). The most important directions for Serbia in the application of Industry 4.0 include: industrial policy for Industry 4.0, education for Industry 4.0 (higher / secondary education), research for Industry 4.0, and especially applied research and readiness of SMEs for Industry 4.0, as well as the application of this model in practice. This paper presents the development and application of the Industry 4.0 model in Serbia, through the activities of the Faculty of Mechanical Engineering in Belgrade, from 2015 until today, with special reference to the application of Industry 4.0 in mining.

AB  - The present paper studies the impingement of compressible air jet on a flat plate primarily from the aspect of its application in the domain of pneumatic metrology, i.e. in cases of small distance between the jet nozzle exit and the flat plate. Besides this direct application in the area of pneumatic metrology, the distance between the nozzle exit and the flat plate has been considerably increased and the case of a free jet was analysed with a view to compare the results applicable in various domains. This experimental study demonstrates that the structures of a free jet and this special case of an impingement jet are totally different. In the pressure distribution of the impingement jet, pressure discontinuity above the flat plate may occur, which is shown to be the result of low intensity shock waves and transonic flow. The experimental results show that the pneumatic sensitivity of a pneumatic comparator is a function of the supply pressure and the internal orifice diameter, as well as that the impingement air jet is a typical case of non-isentropic flow.

Cilj rada: Svrha ovog preglednog rada je razumevanje uloge Industrije 4.0 u oblasti medicine i stomatologije i identifikacija pravaca istraživanja, uključujući i buduće primene, posebno za covid-19. Materijal i metod: Izvršena je detaljna analiza radova o Industriji 4.0 u medicini, stomatologiji i srodnim oblastima i identifikovane moguće primene i pravci istraživanja, a posebno za covid-19. Rezultat: Kroz ovu preglednu studiju identifikovali smo različite tehnologije, mogućnosti i istraživački status Industrije 4.0 u oblasti medicine, stomatologije i covid-19 pandemije, kroz 19 oblasti primene. Možemo reći da će Industrija 4.0 postati suštinski deo sutrašnje pametne fabrike medicinskih i stomatoloških uređaja. Zaključak: Industrija 4.0 pokazuje široku mogućnost proizvodnje novo prilagođenih implantata (medicinskih i stomatoloških) i inovativnih alata i instrumenata za oblast medicine i stomatologije.

AB  - In the year 2019th, 77.000 new ventilators were more than enough to meet the market demand worldwide. However, during the peak of the COVID-19 pandemic, large cities alone need more than additional 30.000 machines per city (example: New York). At the time, almost all ventilator manufacturers have boosted their production by 30-50% but, they still weren’t able to deliver the required production growth. One way to solve the medical devices shortage problem is the development and large-scale production of new medical devices. The main issue of this approach is the complexity of medical devices as a mechanical system, especially taking into account the obligatory medical verification. That’s the main reason why existing standardized medical equipment should be used as a basis for the development of the new prototypes. This approach is implemented during the development of the new mechanical ventilator. Used methods include all traditional product development activities (such as the definition of desired characteristics, comparative analysis of literature and existing ventilators, definition of different variant solutions, and selection of best technical solution for further development) followed by the modern product development methods: 3d modeling, FMEA and rapid prototyping using advanced 3d printers. The verification of the new mechanical ventilator prototype was successfully performed, setting up a basis for further improvements. The developed prototype has numerous advantages compared to the competition (i.e. it is much cheaper and easily produced with comparable technical characteristics) but its main advantage is a brand-new system for patients’ exile air sterilization and filtration.

AB  - The gradual increase in the volume of electric vehicles leads engineers to solve completely new problems of NVH (noise, vibration and harshness) One of the solutions is the use of rubber mounts to hold the electric motor of the vehicle's powertrain. This article deals with a rubber mount used to insulate vibrations from the propulsion system to the rest of the vehicle. Since the electric motor produces a different spectrum of vibrations and noise than the internal combustion engine (it produces lower amplitudes, but in a wider frequency band), it is necessary to adapt the design of the rubber mounts. This article deals with the possibility of using a mathematical model that can be used in a virtual vehicle model. It compares the differences in the vibrations of the internal combustion engine and the electric motor. From the results measured on the experimental model, the parameters for the FEM model and the mathematical model were identified. At the end of the article, the results from the experiment are compared with the results from the simulations.

AB  - Based on the analogy between manufacturing and mining (i.e. ore 'production'), smart mining has four dimensions: (i) advanced digital-oriented technologies (such as Cloud computing and the Internet of things) with automated Cyber-Physical Systems (CPSs), adaptable production processes (dependent on working conditions) and production volume control (with optimal resource consumption); (ii) smart maintenance of CPSs; (iii) new ways for workers to perform their activities, using advanced digital-oriented technologies; and (iv) smart supply-chain (procurement of materials and spare parts / products delivery). This paper presents a case study on the smart mining approach implemented at a coal mining system in Serbia.

AB  - This paper contains elements of a comprehensive research devoted to the dynamic behavior of radial ball bearings in real working conditions. The general motivation for this topic comes from the requirements for high performance operation of bearings within complex mechanical systems, defined in many industrial branches during the last decades. The discussion of the fundamental postulates of the approach used for analyzing the vibration response of rolling ball bearings in order to select the optimal working conditions is given. The certain simplifications and reductions used for analyzing the radial ball bearings are explained. The developed procedure can be used for research of influence of different damages and variable operation conditions on the rolling bearings dynamics. The detail analyses of the dynamic behavior of rolling bearings are performed for particular types of radial ball bearings in two case studies: For the damaged outer raceway surface in accordance with real fatigue damage shapes and dimensions and, for variable working temperature. Obtained results are shown by comparative diagrams of vibration and phase plane portraits. Presented results could be a base for more widely research of nonlinear dynamics of radial ball bearings with different damages and for the application of phase plane analysis in order to choose the optimal operation conditions.

AB  - In the framework of Industry 4.0, new specific or improved methods formonitoring and prediction of operational conditions of machine elements are required.Ball bearings are among the elements with high impact on safety and reliability ofmechanical systems operation. Hence, the development of accurate methods for theirworking conditions monitoring is one of the important tasks within this framework. Inthis paper, the development of 3D Finite Element Model for deep groove ball bearingswith defects on ring races is described in detail and its place in the new monitoringmethods is discussed. Special attention is paid to the modeling of contact finiteelements and selection of FEA parameters for fast and secure convergence duringnon-linear calculations.

AB  - New powertrain design poses new challenges in terms of driveline vibration or ultimately in terms of NVH (Noise Vibration Harshness). Current state of the technology for vibration damping in car powertrains is the so-called Dual Mass Flywheel (DMF). The paper deals with creation of MBD model of double mass flywheel based on CAD model of dual mass flywheel produced by ZF. Parameters of virtual model are tuned and compared with experimental measures of dual mass flywheel. Second part of paper deals with dynamic simulation of DMF. Model used for dynamic simulation consists of two bodies and torsion spring with stiffness computed from simulation of full DMF model.

AB  - Increasing the volume of the production of vehicles with electric or hybrid powertrain also leads to specific activities for research and development in this segment. One of the current areas that present the paper deals with the idea of reducing structure-borne vibration from electric powertrain to the vehicle interior. Electric powertrain and mainly electric motor are a source of high-frequency vibration up to 3000 Hz. On the other side, the internal combustion engine is a source of significantly lower frequencies. For this reason, a different approach is needed when designing electric powertrain mounts. To reduce the vibration transfer to the structures of the vehicle, rubber-metal motor mounts are used. Rubber-metal motor mount must have specific dynamic properties such as the dynamic stiffness, the loss angle and hysteresis properties. Hysteresis properties are important to define the damping properties of the rubber-metal motor mount. The Bouc-Wen model was used for modeling of hysteresis properties. The results from simulations are compared with experimental data.

AB  - The article discusses the influence of inert gases (carbon dioxide and nitrogen) in a mixture with natural gas on power and economic parameters of the internal combustion engine LGW 702 designed for micro-cogeneration units. The experimental measurements were made under various engine operating modes and under various compositions of fuel mixtures. The aim of the experiment was to analyze and assess the full impact of the inert components in the gaseous fuel, especially on the particular integral parameters, as well as on the internal combustion engine parameters relating to the course of burning the mixture. Experimental results indicate a decrease in performance parameters and an increase in specific fuel consumption with an increase in the proportion of internal gases in the mixture. Increasing proportion of inert gases leads to decreasing maximum pressure in the cylinder (a decrease approximately by 50% with the mixture CO2NG50 or by 30% with the mixture N2NG50, compared to natural gas) and the position of maximum pressure value is shifted further into the area of expansion stroke.

AB  - This paper presents the development of a methodology for calculating radial ball bearing vibrations. First, analytical and numerical models were developed and then, the obtained results were experimentally verified. In the experiment, a test rig for a dynamic testing of bearings subjected to an external load was used. Special attention was paid to the analysis of the total bearing deformations and stiffness, being the main parameters that define the dynamic behaviour of a bearing. In order to determine total deformations of a ball bearing as an assembly, a finite element model of the bearing was developed. The results obtained from the new methodology for a particular ball bearing type have been verified by experimental results. The obtained correlations of the experimental and the numerical results are about 2.5%. Based on the calculations and the experimental testing of the chosen ball bearing type, under conditions of a variable radial load, the analysis of the influence of the radial load on the dynamic behaviour of a ball bearing was performed. The analysis of the obtained results showed that the vibration amplitude increases with a similar multiple factor as loads increase.

AB  - The basic framework of the Industry 4.0 as an approach and philosophy implies the introduction of new procedures and principles, as well as the development and improvement of machine systems towards the introduction of a high level of manufacturing digitalization. In order to meet the achievements of Industry 4.0, very significant changes are also required in the design, monitoring and maintenance phases of machinery. Therefore, all the research and advancements in the field of calculation and design of machine elements and assemblies have to be observed within the paradigm of Industry 4.0. This paper outlines the main research tasks and aims within the determination of basic principles and methods for suiting and improving machine elements and systems in the context of the requirements of the Industry 4.0. Also, the part of the paper gives the description of the new improved methodology and systems for monitoring the parameters of rolling bearings during their operation, which would significantly contribute to the prediction of the possible failure of the rolling bearings and lead to important savings. The developed methodology is a sample for new trends in the context of the vision of Industry 4.0 machinery and respects the requirements for safety, energy efficiency and reliability.

AB  - Purpose This paper aims to present the methodology to determine Archard's wear coefficient. By applying this coefficient into the numerical simulation of wear, it is possible to predict wear without long lasting and usually expensive experiments. Design/methodology/approach To determine necessary particles of Archard's equation and calculate wear coefficient K, an experimental investigation is proposed. Afterwards, the wear simulation is executed in FEM software ANSYS 18.1. Analytical method is offered to determine worn volume for cylinder-in-cylinder contact, based on "inclination" of inner cylinder. Findings Comparing the value of Archard's coefficient obtained by this experimental investigation with the values from the literature for the similar materials, high correlation is noted. Furthermore, numerically calculated contact pressure is confirmed with analytical method. Trend of pressure decrease due to wearing process, as well as due to increase of contact surface is observed. Practical implications - Since the prediction of the wear is closely related to the life cycle assessment of bearings, and the machines in general, it has significant practical importance for designers. Originality/ value - Determination of Archard's coefficient is usually performed by conventional pin-on-disk tribometers. This methodology offers a different approach for the determination of Archard's wear coefficient for cylinder-in-cylinder contact, which is convenient for shaft-sliding bearing contact.

AB  - The efficiency of thermal power plants significantly depends on the efficiency of belt conveyor systems. Conveyor idlers, as key parts of belt conveyors, are often the main cause of bulk material transportation systems failures. Testing the operational characteristics of conveyor idlers in laboratory and exploitation conditions is a prerequisite for any progress in the field of increasing energy efficiency of conveyor systems. This paper describes an analysis and discussion of testing results for different types of conveyor idlers, in terms of their performances under the act of predefined radial load. Tests were conducted on a new conveyor idler's testing machine developed at the University of Belgrade-Faculty of Mechanical Engineering. The presented tests are performed in order to determine the quality of carrying and return conveyor idlers. The obtained results will help in solving the key problems in the critical areas of conveyor systems and will increase their energy efficiency. Finally, the expected results can potentially reduce the financial and energy losses which conveyor idlers cause in belt conveyor systems, as well as in the whole system of thermal power plants.

AB  - Magnetoplasma accelerator (MPA) accelerates and compresses plasma formed within the electrode system during the process of capacitor discharge. The lifetime of the compressed plasma flow is around 150 mu s, plasma velocity is up to 100 km/s, electron density and temperature are close to 10(23) m(-3) and 2 eV, respectively. Energy and energy flux density distribution along the axis of discharge have been measured for different working gases: hydrogen, helium with 5% of hydrogen and argon with the aim of determination of the optimal position and type of the gas for investigation of the plasma-material interaction. Steel (type 16 MnCr5) samples have been treated with plasma pulses, using helium with 5% of hydrogen as a working gas. Modification of the steel surface under high thermal loads was studied and roughness and hardness of steel targets were measured before and after plasma treatment. Improvement of physical and mechanical properties of a treated type of steel has been achieved. Additionally, the mean value of the electron density in the region of the plasma-surface interaction has been determined.
