AB  - A parabolic trough collector (PTC) is one of the most common concentrated solar power systems 
(CPS). Usually, this system is seen with a fixed focal point and parabolic mirrors rotate around this 
point. These mirrors are concentrating sun’s rays into the focal point and thus heating it. The rotation 
of mirrors is set to follow the movement of the Sun. The idea of this paper is to analyse a PTC system 
when parabolic-shaped mirrors are fixed and the focal point is moving to absorb as much sun’s rays 
as possible. When a parabola is placed to reflect rays into the point, these rays are perpendicular to 
the directrix of that parabola. Once this ray starts to change its angle, so does the focal point change 
in two ways. The first one is a dimension of a focal point- not a point but a cluster of points that can be 
assembled on a surface shaped like a cylinder, for example. A second change that occurs is that 
location of the focal point shifts to a different position. This paper shows what happens to the focal 
point of parabolic-shaped mirrors when they are fixed on the ground and entering rays follow the path 
of Sun rays. This analysis will take into consideration one location (for its latitude and longitude) and 
for that location azimuth and altitude will be calculated and implemented on this PTC system.

AB  - Acoustic signals have been used widely to detect the integrity of metal parts and the soundness of their contact. Diverse methods are developed to evaluate the actual quality of metal-to-metal contact having a lubricating layer. These methods are sensitive to the sound waves resulting from the sliding and rolling contact of the adjacent items. The ongoing research and operational experience created an effective and reliable method for acoustic detection of rolling bearing damage. Sound waves are detected by an appropriate transducer (sensor). The signal is processed, and the resulting root-mean-square (RMS) voltage is tracked. An increase in the voltage level indicates deterioration in bearing conditions. In practice, however, such an application almost always involves several considerations, including a significant amount of interfering background noises, unacceptable sound wave attenuations, and inaccessibility of the desired sensor locations.

AB  - A four-bar linkage mechanism to accomplish different tasks. Those mechanisms is used in a vast number of application in different fields  accomplish different tasks. Those mechanisms can have some theoretical and practical limitations, de-pending on their applications. From a theoretical standpoint, four-bar linkages mechanisms are modelled with rigid bodies with rotary joints, and, from a practi-cal standpoint, those joints require additional maintenance during operation and lubrication. On the other hand, compliant mechanisms do not have joints in a classical sense but the relative movement between linkages is accomplished through the deformation. Certain segments of the mechanism are thinned to achieve relatively localized large deformation, which will allow movement be-tween stiffer segments (linkages) of the mechanism. Compliant mechanisms have several advantages and disadvantages compared to classical mechanisms. Those mechanisms are essentially one part that doesn't require any lubrication and there is also no backslash between movable parts. Neverless, due to the mechanism de-sign principles, the strength of the overall structure and movement range can be very limited. Besides basic parametres, in the design process of complaint mech-anisms, the dimensions type of its “joints” has sn interesting part of overall per-formance. The stiffness of theese joints and their size will cause the relative movement of the rotary axis between linkages. The variable position of the rotary axis between adjacent linkages gives one more degree of freedom in the design process. This phenomenon opens up possibilities for fine-tuning, especially in cases where a classical mechanism is used as a design template for compliant mechanisms. An example of this process is a classical mechanism that produces approximately straight-line motion where the transition to a compliant mechanism can further improve straightness of its trajectory.

for the formation of technical systems. The ability that some geometric structures are able to 
withstand a certain level of deformation, was used to replace joints in certain assemblies of technical 
systems. Now all movements are accomplished with the deformation of geometrical structures. 
Obtained results from simulations, define the level of deformation that structures can withstand. 
Designing of 3D models and simulations was conducted in SOLIDWORKS 2016. Several different 
structures of metamaterials will be examined. 64 simulations were conducted by changing the internal 
structure, thickness, and orientation of metamaterials. For each simulation results were presented as 
stresses and displacements. Additionally, three models of pliers have been simulated, and their 
results were compared with results from previous simulations.

AB  - Out of many geometric curves, parabola stands out in usage in concentrated solar power (CSP). Its reflective properties allow reflecting light into one single point. This paper gives insight into the geometry of parabolic trough concentrators from the point of designing a size of a collector regarding two inputs. The first input is a parameter of the parabola which, provides the shape and size of the reflecting surface. A second input is a deviation of the angle of incoming light. Usually, this angle is perpendicular to the parabola's directrix, but the sizing of the collector tube must consider that because manufacturing or any other inaccuracy reflected ray might disperse from the focal point of the parabola. A detailed view of this dissipation of reflected rays depending on the entering ray's angle will be explained in the paper. A geometrical and algebraic display will be given, and a formula for sizing collector will be derived. In this equation two input values will be combined: parameter of parabola and value of the deviation of entering ray of light. This gained formula can later be used to show dependence between these two inputs and provide the answer to a question: is there a way to construct a mechanism that will move the focal point in accordance to changing entering angle and parameter of a parabola?

AB  - This paper describes and explains the synthesis of an astronomical clock mechanism which displays the mean position of the Sun, the Moon, the lunar node and zodiac circle as well as the Moon phases and their motion during the year as seen from the Earth. The clock face represents the stereographic projection of the celestial equator, celestial tropics, zodiac circle (ecliptic) and horizon for the latitude of Belgrade from the north celestial pole to the equator plane. The observed motions of celestial objects are realized by a set of clock gear trains with properly calculated gear ratios. The method of continued fraction is applied in the computation of proper and practically applicable gear ratios of the clock gear trains. The fully operational 3D model of the astronomical clock is created and the motion study of its operation is accomplished by using the SolidWorks 2016 application. The simulation results are compared with the ephemeris data and the detected differences are used to evaluate the long-term accuracy of the astronomical clock operation. The presented methods of the clock mechanism synthesis can be useful for the design, maintenance and conservation of large-scale city astronomical clocks since these clocks represent a precious historical and cultural heritage of European civilization.

AB  - The paper presents a synthesis of mechanisms needed to realize an approximate rectilinear motion. The synthesis was performed at several different levels, by changing different geometric parameters of the mechanism itself. The software package SolidWorks2020 was used for the analysis and synthesis of mechanisms. The main goal of using this method was to provide us a possible solution to turn the classic type of mechanism into the compliant mechanism. Four different mechanisms were used for specific examples, but the idea was to form a methodology for converting classical mechanisms into compliant mechanisms.

AB  - An intense increase of research in “green” technologies brings a variety of science fields in common goal to contribute sustainable development. Such an example is concentrated solar power (CSP) which combines knowledge of astronomy, thermodynamics, mechatronics and geometry in one final product. The solar power tower is a system that uses an array of flat, movable mirrors called heliostats to focus Sun’s rays into one focal point which is usually a boiler located on top of central collector tower. This paper will present one possible design of solar power tower by using geometry to relocate its focal point. Most common solutions for solar power tower are shown and they are based on concept where boiler is in plain sight. Idea behind this relocation of focal point in novel construction is that boiler will be isolated from environment conditions and by doing so it can preserve more thermal energy during night. This can be achieved by installing additional mirror on solar power tower which has a shape as revolved partial ellipse. Here will be explained how this additional mirror can be used as economiser for fluid that is being heated in solar power. Paper also explains use of “fat point” at focal point and thus compensate errors that can occur if rays from heliostat are inaccurate.

AB  - At first glance, the human knee can look like a simple rotational joint but the real knee has more complex geometry and kinematics. Kinematics of the human knee depends on its geometry and applied analysis showed that it is a rolling joint, where the upper part of tibia rolling on femur lower end. Such kind of motion can be simply explained with rolling curves generation. In the simplest case, circle rotates on a flat surface and each point on circle circumference will generate one cycloid. Curves defined through this method highly depend on the shape of the rolling object and shape of the surface where the object roles. 
In the literature complex, geometry and movement of the human knee can be solved with a relatively complex mechanism that can reproduce real movement or simply by replacing knee with one rotational joint. Application of the new popular technologies (3D printing, CAD) and new approaches of mechanisms design (where the mechanism is produced as one part, and its geometrical shape allows relative movement through elastics deformation), can simplify the overall geometry and kinematic of an artificial knee joint. This will further simplify manufacturing processes, lower costs of the knee and leg prosthetics, and increase its durability by reducing the number of movable parts.

AB  - This paper is a result of plenty researches on dynamic of the process on FD320A milling machine. We try to propose also a method for determination of the displacement for the contact surface using an analysis with finite elements. Before this, an important problem is achievement a model with finite elements that must be the best approximation of the tool-machine structure on one hand, and on the other is how to make the geometric model for the contact surface. We collected also some experimental data. Theoretical studies are near to the experimental data, registered with an acquisition system sets on the shaft’s slides of the final elements for the milling machine. We made a dynamic analysis with variable forces; being well known that the vibrations appeared may cause large displacements and severe stresses in the concrete situations. The analysis proves that the displacements are in admissible limits and have not major influences on the quality of the processing surfaces.

AB  - In the last couple of years, 3D printing has become one of the most popular manufacturing techniques in designing of the new prototype parts, mechanisms and machines. Available and relatively cheap 3D printing techniques allows fast manufacturing of different complicate prototypes (rapid prototyping) by using plastics as base material, like FDM. In the most cases, these prototypes are used only for functionality testing and design analyzing, yet that is a small part of the possibilities that 3D printing can give in parts design. For example, 3D printing can be utilized for creation of the cheap personalized limb prosthesis, toward specific needs of each patient. One of the biggest advantages of the method is production of the complex geometric shapes, done layer by layer, which provides a new level of freedom in part design and significantly impact their final characteristics, since conventional techniques of parts manufacturing have many limitations. By modifying the inner geometric structure of the parts produced from regular material, new properties of the engineered part are obtained, with different behavior, which the starting material didn't have. This, engineered materials are named metamaterials. Using the metamaterials it is possible to produce parts with properties that doesn't appear in nature. This paper will present how new parts, mechanisms, and machines can be designed and manufactured using metamaterials and 3D printing.

This material is very strong and manufactured parts are not very flexible. By using metamaterials some models of human running prosthesis were created and a number of simulations were made through SolidWorks Design Study package. Used approach allows finding of the best solution for custom-made human running prosthesis with the best characteristics.
Present paper gives the evidence that using of smart geometrical design of inner structure of various parts and models to reduce its mass and improve their mechanical characteristics is possible. Also, obtained model is suitable for 3D printing and it can be opportunity to product cheap prosthesis for a large number of people with disability.

AB  - This paper gives a scope of a course called Aesthetics Design at the Faculty of Mechanical 
Engineering, University in Belgrade, Serbia. At this course students learn about standards 
and laws in process of product design. With the knowledge gained at the course students 
are able to develop more profound ability of aesthetic evaluation and form aesthetic judge ment in creating certain mechanical products such as cars, motorcycles, etc. Practical part 
of this course includes creating a product by using a 3D CAD software which has both aes thetic value and practical usage. Students present their products to other students and 
then evaluate each others’ achievement. This course is taught at undergraduate studies 
(B.Sc.) and it is in the group of general subjects/courses.
The origin of the word aesthetics comes from Greek word aisthesis that can be rough ly translated as sensation or understanding through perception. It usually represents a 
branch of philosophy that studies creation and appreciation of beauty in art. There are 
many applications for aesthetics – in architecture, fashion, website design, music etc. Basi cally everything that surrounds us can be subjected to certain kind of aesthetical judgment 
and that is the reason for the rising of awareness of importance for aesthetic in all occupa tions. For instance, while designing a product an engineer must take in consideration many 
aspects before dispatching product on market. These aspects include: robustness, lifetime 
expectancy, price, ergonomics, etc. One of this aspects is the appearance of a product. Av erage buyer makes its first impression based on product appearance. The more appealing a 
product, the higher probability that buyer will purchase it.

AB  - For many years, various ways of fixing skiing shoes for skiing have been used. With the development of technology that is applied in this very popular sport, there is an increasing need for enhanced conditions related to personal safety of users. Over time different kind of mechanisms were used for this purpose differed. Currently, the most effective way to safely connect the ski boot/ski shoes to the ski is achieved by a camber-blocking mechanism. In this paper, we conducted analysis of a ski binding using the SolidWorks2018 software package, checked its functioning under the given conditions (which are very close to the real conditions) and come up with results that could be used in practice. Results were analyzed and the results were compared mutually in order to receive the most optimal solutions. Also, a methodology used in this paper is the same as one developed for the teaching process in the subject Design of Mechanisms at Bachelor Studies at the Belgrade Faculty of Mechanical Engineering.

AB  - This paper exposes and explains the synthesis of a mechanism, the Eclipses Abacus, by which the date of solar and lunar eclipses can be predicted and determined sufficiently accurately. Moreover, a three-dimensional (3D) model of this mechanical device is created by using Solid Works application and the simulation of its operation is accomplished by which the accuracy of its predictions can be demonstrated and inspected.

AB  - This paper investigate influence of different geometrical structures on new concepts for formation of 
technical systems. Ability that some geometric structures are able to withstand a certain level of 
deformation, was used to replace joints in certain assemblies of technical systems. Now all 
movements are accomplished with deformation of geometrical structures. Obtained results from 
simulations, define level of deformation which structures can withstand. Designing of 3D models and 
simulations were conducted in SOLIDWORKS 2016. 
Several different structure of metamaterials will be examined. 64 simulations were conducted by 
changing internal structure, thickness and orientation of metamaterials. For each simulation results 
were presented as stresses and displacements. Additionally three model of pliers have been 
simulated, and its results were compared with results from previous simulations.

AB  - A Mechanical Integrator is a mechanical device by which the continual integration of the input variable 
value can be obtained. This paper explains the operational principles and discloses the simulation and 
motion study results of the mechanical integrator 3D model assembly. Specifically, 3D models of the 
input function generator, the ball and disc integrator and the output x-y plotter are created and their 
operations are simulated. This work is significant mainly for education in the fields of solid modelling, 
mechanism synthesis and scientific visualization of the mechanism motion and operation. In particular, 
the motion analysis presented in this paper visualizes and discloses the mutual relationship between 
the integration calculus as the mathematical operation and the geometrical and kinematical 
characteristics of one special type of mechanical computing device.

AB  - This paper gives an insight into the design of concentrating solar power (CSP) systems. The basic
design of several types of CSP system is presented alongside their advantages and disadvantages. 
These advantages and disadvantages are based on their application and construction details and the 
paper shows how to select the most convenient CSP system. After presenting these types of CSP 
systems, an example of a new type of design is explained that presents a combination of several other 
solar concentrators.
