The scientific substantiation of SIN-beam installation into the load-bearing structure of a nonversatile filling car was carried out. The research was carried out with regard to the freight car model 12-757 produced by Krukivsky Carriage Works. Use of SIN-beams as the main bearing elements of the frame reduces its weight by 6% in comparison with the frame of the prototype car.

Investigation of Behavior and Analysis of Mechanical Properties of Carbon Nanotubes under Different Loads

In this research, the behavior and mechanical properties of carbon nanotubes under different loads (tensile and torsional) have been investigated by the finite element method with SOLIDWORKS Simulation software. Examination of carbon nanotubes by selecting the wrong element and large size of the elements leads to high error in the model and in contrast to the high mesh density increases the analysis time, accumulation of rounding error and finally causes stiffness in the carbon structure. According to the obtained results, the obtained elastic properties for the model with beam element are about 9% more than the three-dimensional model and also about 11% more than the continuous shell model. Also, the elastic properties of the three-dimensional model are about 2% higher than the continuous shell model. Examining the results of these models, it can be seen that for both armature and zigzag structures, shell, beam and three-dimensional elements give better results than each other, respectively. Understanding the results of this study helps to select the best type of element and arrangement for the analysis of carbon nanotubes in different conditions and applications. To check the accuracy of the results, the buckling behavior of carbon nanotubes with both zigzag and armature structures with beam, shell and three-dimensional elements under eccentricity has been performed. The results show that the selection of shell elements for carbon nanotubes with any structure gives better results and is in good agreement with the other reported results.

Reinforcement learning is a type of machine learning algorithm. These algorithms interact with the model of the environment in which the robotic system is supposed to be used, and make it possible to obtain relatively simple approximations of effective sets of system actions to achieve the set goal. The use of reinforcement learning will allow training the model on server hardware, and in the final system use already trained neural networks, the complexity of calculating the response of which directly depends on their topology.

The object of research is the supporting structure of the pellet wagon with the actual dimensions of the supporting elements. One of the most problematic areas is the determination of the indicators of dynamics and strength of the supporting structure of the hopper wagon with the actual dimensions of the structural elements.
 A study of the dynamic loading of the supporting structure of the hopper wagon was carried out. At the same time, the actual dimensions of the structural elements were determined by means of field studies. Mathematical modeling of the dynamic loading of the load-carrying structure of a hopper wagon with the actual dimensions of structural elements was carried out by means of mathematical modeling. The studies were carried out in a flat coordinate system. The presence of three degrees of freedom of the supporting structure of the hopper wagon was taken into account: vibrations of twitching, bouncing and galloping. Differential equations were solved in the MathCad software package. In doing so, they were reduced to the Cauchy normal form, and then integrated using the Runge-Kutta method. It was found that the maximum value of the acceleration acting on the supporting structure of the hopper wagon is 38.5 m/s2, which is 2.7% higher than the acceleration of the supporting structure with nominal dimensions.
 Computer simulation of the dynamic loading of the supporting structure of the hopper wagon was carried out. The calculation was carried out using the finite element method in the SolidWorks Simulation (CosmosWorks) software package. It was found that the maximum accelerations are concentrated in the middle part of the supporting structure of the hopper wagon and amount to 36.2 m/s2. The F-criterion was used to verify the developed model. The calculations showed that the calculated value of the criterion is Fc = 1.09 and is less than the table value Ft = 3.29. The adequacy hypothesis is not rejected.
 The natural frequencies and vibration modes of the hopper wagon supporting structure were determined. It has been established that the values of natural vibration frequencies of the hopper wagon bearing structure with the actual dimensions of the structural elements are within the permissible limits.
 The research will contribute to the creation of relevant developments to extend the service life of wagons that have exhausted their standard resource, as well as to increase the efficiency of railway transport operation.

A special feature of the car is the presence of elastic elements in the main longitudinal beams of the frame. This could improve the fatigue strength of the carrying structure of the platform car under operational modes.
 Mathematical modeling was carried out to determine the dynamic load on the carrying structure of the platform car. The fluctuations of bouncing were taken into consideration. It has been established that the vertical acceleration of the carrying structure of the platform car without cargo is about 2.0 m/s2 (0.2 g). In this case, the vertical accelerations that act on the carrying structure of the platform car are lower by 15 % as compared to the prototype wagon.

Many researches had been conducted on natural fiber nanocomposites to replace conventional material in vehicle application. This is due to the environmental sustainability awareness that is arising nowadays. The topic of this research focuses on the development of coir fiber-reinforced nanocomposite in Shell Eco-Marathon vehicle body application. Shell Eco-Marathon vehicle is designed to be lightweight to improve the efficiency of the vehicle. Coir fiber-reinforced nanocomposite is the combination of coir fiber, silica nanoparticles and epoxy resin as a composite material. The parameters involved in this research include the weight percentage of coir fiber, weight percentage of silica nanoparticles and force applied to the simulated model.

Two-matrix pellet mill

Industrial development and human livelihoods are directly dependent on traditional fuels, the main ones being oil, gas and coal. The main alternative that can reduce the use of these energy sources is plant biomass. It is made from organic residues from agriculture and the timber industry. In addition, the use of biomass is safe for the environment and human health. It should be noted that biomass requires the development of new technologies for processing it into fuel. This article analyzes the use of a two-matrix pellet mill for the production of pellets from organic raw materials. A methodology for calculating the main structural parameters of the pelletizer is proposed, the design features of the structure are substantiated, and the main force parameters of the device are modeled using the Solidworks simulations program. The main feature of the proposed two-matrix pellet mill is to reduce the metal consumption of the equipment and increase the productivity of the technological process of pelletizing organic waste from agricultural products by placing two dies on one base plate so that the working area of the pelletizing process is located between them, and the pressing rollers evenly press organic raw materials into the holes of the filter of both dies in turn. As a result of the research and development work, a new two-matrix pelletizer was designed, which can be used both in stationary installations and in mobile combines for straw pelletizing in the field.

Simulating modular rolling guides elastic properties

Due to high performance characteristics of the modular rolling guides, they are widely used in the contemporary CNC machine designs by major manufacturers. The wrong choice of the guide characteristics can result in excessive cost of guides or maintenance, as well as insufficient rigidity of the machine. Various methods of modular rolling guides elastic properties studying and machine tool structure deformation analysis are known. Most of them are analytical solutions in which the cartridge body and the rail are considered non-deformable. The purpose of this study is to develop a hybrid numerical-analytical model based on the FEM and analytical solution. This approach makes it possible to take into account the joint deformation of bodies (cartridge body, rail, etc.) and contact deformation of the balls and raceways of the guides. The study was carried out in SolidWorks Simulation application. The simulation results correlate with the experimental data well. The displacements of the cartridge have lower values than the values obtained using the FEM model. To evaluate the significance of the model nonlinearity and the possibility of its linearization, a series of calculations of the gear hobbing machine structure elements were performed. The hybrid numerical-analytical model created improves the adequacy of the simulation results.

Analysis of Indentation Test Using Solid Works Simulation

The finite element analysis of spherical indentation was conducted using the SolidWorks simulation software. The relationship between the load and indention was determined, and comparison with the Hertzian solution was made. In this study, spherical indenters of diameter 5, 10 and 15 mm were used to assess the effect of indenter radius on indentation response at a specified load. The outcome of our study shows that the resulting load-indentation response does not closely correlate; as a result, a difference of 21.2% was observed between the hertz solution and simulated results. The increase in diameter was observed to be associated with the corresponding decrease in indentation depth and the indentation stress. The von Mises stress contour at maximum load was analysed and was observed to be the highest on the indented surface beneath the indenter. The resultant displacement contour shows a uniform displacement distribution.
