Aumento de calidad en uniones soldadas de estructuras de paredes delgadas mediante modelo de simulación

El módulo de cálculo de simulación y el paquete de software solidworks han ayudado a definir la forma y las dimensiones óptimas de uniones soldadas simples que pueden servir de base para calcular los parámetros de proceso de soldadura. Habiendo comparado los modelos con diferentes secciones transversales de soldadura, el autor ha determinado que la altura y el ancho de la soldadura no afectan significativamente la concentración de tensión, y la concentración y el valor de la tensión dependen principalmente de la forma del latido de la raíz y del punto de separación entre las partes soldadas.

The paper considers the approach to the estimation of the stress-strain state of a lifting-transport machine, which has been in operation for a long time, with the introduction of mathematical modeling, namely, the introduction of the finite element method for determining the stress fields and the identification of the most dangerous zones during the operational load. Experimental data were used to obtain real loads occurring in the crane metalwork. A review of the sources shows that the elements of the metalwork of all cranes have a personal prior history of strength and deformation, which is difficult to overestimate, especially the cranes that have been in operation for decades. It is substantiated that the parameters of stiffness and strength determined in the material exceed the permissible error of linear and angular dimensions. Obviously, modern calculations of metal structures should be carried out with the obligatory application of numerical experiment and determination of mechanical parameters by computer methods to ensure the operation of cranes without damage. On the basis of the obtained results, conclusions were drawn about the current state of the crane's metalwork and the conditions for the possibility of further operation of its crane. Hazardous locations in the crane metal structure have been identified, which can be a source of destruction, for further measurements of the physical properties of the metal and the conclusion in the state of the Crane metal structure. The model of the mooring container reloader was created with the introduction of the Solid Works software package. The metal structure of the mooring container reloader was calculated numerically using CAD. The stressed and deformed state in accordance with the requirements for hoisting-and-transport machines were determined. Hazardous locations in the crane metal structure, which can be a source of destruction, have been determined to further measure the physical properties of the metal and to conclude on the state of the crane metal structure. The proposed method of solving the problem can be applied in most cases of trucks.

A comparative finite analysis of the mechanical behavior of ProTaper NEXT and WaveOne rotary files

Finite element analysis was used to evaluate the stress distribution, estimate the residual stresses, bending, and amount of displacement of two nickel-titanium instruments manufactured by the same M-wire technology but with different cross-section.Materials and methodsTwo brands of Ni-Ti instruments ProTaper NEXT (Dentsply Maillefer), and WaveOne (Dentsply Maillefer, Ballaigues, Switzerland) were scanned with stereomicroscope to produce a two-dimensional model for each file using computer-aided design programs (CAD) (SolidWorks software package), which then was converted into stereolithographic extension to be readable by programming software (MATLAB software) to produce three-dimensional models. The mathematical analysis of files was performed on SolidWorks software package. The mechanical behavior of the two files was analyzed numerically in a SolidWorks package to simulate and measure torsion, bending, and file displacement. Application of a shear moment (torsion) 2.5 N/mm moment of force was applied to the shaft in a clockwise direction, while the last 4 mm of the tip was rigidly constrained to evaluate the stress distribution on each file. As for Cantilever bending, a concentrated load of 1 N at the tip of the file with its shaft rigidly held in place was applied for the finite element models. The vertical displacement was measured and the von Mises stress distribution was evaluated.ResultsThe WaveOne file showed higher torsional stresses accumulation than those accumulated in the ProTaper NEXT. While the ProTaper NEXT showed more bending and file displacement than those showed by WaveOne file.ConclusionsThe two files rotary models highlighted the different mechanical properties of the files although they share the same manufactured technology M-wire. The ProTaper NEXT showed less torsional stress accumulation and more bending properties.

Method of calculating the heat and stress-deformed state of the cylinder head of a transport diesel with liquid cooling

In an internal combustion engine (ICE), stresses arise from the action of a variable gas force and from a variable temperature due to the combustion of fuel in the combustion chamber in the cylinder head and piston, while the thermal stresses are much higher than the stresses from the power load. Therefore, at the design stage of a new engine design, they are calculating the durability of heat-stressed parts, since they limit the reliability of a piston engine. The paper discusses the method of selecting source data when calculating the thermal and stress-strain state of the cylinder head of a diesel engine using the finite element method and using the Solid Works software package. The stages of creating and preparing a solid model of a cylinder head to create a finite element model are described using the example of the 8ChN12 / 13 diesel engine (KAMAZ 740.75-440). The main loads acting on the cylinder head during the assembly period are considered: efforts from pressing in valve seats and bushings, as well as from tightening the bolts for fastening the head to the crankcase. The shape of the elements for the finite element model of the cylinder head was chosen from the condition of reducing the estimated time. This condition was suited to the shape of a finite element in the form of a tetrahedron with four nodal points. These elements made it possible to reduce the computational grid in cross sections, for example, stress concentration. It is shown that high-frequency temperature fluctuations that occur as a result of the flow of the working process of a piston engine do not affect the thermal strength of the cylinder head, and high-frequency temperature fluctuations due to changes in the engine operating conditions affect. The changes in the basic characteristics of the aluminum alloy from which the cylinder head is made with temperature and cyclic thermomechanical loading of low frequency are given. It is shown that with increasing temperature, the endurance limit of the material decreases at low frequency loads.

Analysis of new forms of orifice plates using computational fluid dynamics

In many technologies, such as process industry or water supply, there is a need to measure fluid flowrates. Orifice plates are the most common instruments for measuring the fluid flowrate through pipelines due to their many advantages. On the other side, their use increases operating costs of industrial plants and pipelines. In this work, three new forms of orifice plates were designed and tested. These new forms and one standard, which served as a reference, were designed by using the SolidWorks software package. The aim of the new designs was energy savings, and consequently reduction of operating costs. Energy savings can be achieved by such a design, which decreases the orifice plate resistance an element of the pipeline. This was achieved by increasing the open part of the orifice plate permitting the fluid flow. CAD models of orifice plates were transferred to STL files that were further used for CFD simulation as well as 3D printing of experimental replicas. According to the proposed algorithm, the new designs were tested by CFD simulation performed in the COMSOL Multiphysics software package, by using a finite-difference method. Equations used were based on the Reynolds form of Navier-Stokes equations (RANS, Reynolds-averaged Navier-Stokes), and the continuity equation for incompressible fluids. Next, as we have proposed in our algorithm of development of new orifice plate designs, experimental orifice plates were made by using 3D printing technology and FDM (Fused Deposition Modeling) procedure and tested at laboratory conditions. The results of laboratory tests were compared with the results of CFD simulation. A considerable amount of energy saving was indicated, which was achieved already by the first of the three new orifice plate forms (V1) as compared to the reference (V0). For the other two proposed forms, the effect of energy savings was considerably lower. By using CFD simulation, data can be obtained based on which a decision can be made whether the new shape of the measuring device should be corrected or is appropriate for further laboratory tests. Based on the presented results it can be concluded that the proposed testing algorithm proved useful in designing new forms of orifice plates.

Designing the half-masks of filter respirators for workers of mining enterprises

The purpose of paper is to develop an algorithm for designing the half-masks of air-purifying respirators and assessment of their safety factor of insulation. To create a 3D model of a head, two-parameter NIOSH tables (National Institute for Occupational Safety and Health) were used. The model drawings were made with the use of Solid works software package. Differential geometrical method based on applying the moving Frénet trihedral was used to design half-masks. Two designs of the respirator half-mask were developed based on the averaged length and width of face (Modification 1), and length of face and lips (Modification 2). As a result of modeling test, the area and perimeter of the mask contact line have been defined. The safety factor of half-mask insulation was calculated theoretically. It has been established that the safety factor of Modification 1 half-mask is 2.5 times higher.

IMPLEMENTATION OF THE PARADIGM OF PLM MODELING WITH CAD PRODUCTS

Modern systems of computer modeling have tremendous functionality, and now the most topical developments are software complexes that include several main modules. This allows us to provide the most optimal product lifecycle management (PLM) within the production process. In our opinion, the ideal basis for PLM modeling is the SolidWorks 2018 software package, which includes the most basic modules and tools for a full production cycle. In our study we used modules such as CAD, CAM and CAE, as well as the Costing tool. The first module is needed to create a three-dimensional model, as well as drawings and specifications on this basis. The CAM module is required to create a processing route, and CAE is required for the engineering analysis of parts and mechanisms. We also believe that the Costing tool is perspective in this case, with the help of which it is possible to analyze the cost of a part or the whole mechanism and optimize the product. In our opinion, the PLM modeling with the use of the above modules will allow future specialists to enter the labor market safely and easily become part of modern production facilities that use progressive methods of output in their activities. The research is based on methods of analysis, synthesis and comparison to determine the feasibility of implementing a paradigm of PLM-modeling using specific modules of the SolidWorks software package. We believe that this approach should be used by students towards the end of the educational process as a generalization of the knowledge that bachelors in mechanical engineering received during the last 4 years of professional training. In our case, a drum dryer was used for PLM, but in fact it could be any machine or mechanism.

REACTOR PROCESS PIPING DISPLACEMENT ASSESSMENT IN THE CONTEXT OF NONSTATIONARY OPERATING PRACTICES

At present, special attention is paid to the issues of industrial safety in oil refineries. This is due to the growing number of accidents in recent years. The most likely are the emergency situations associated with the process pipelines depressurization due to their corrosive wear, the normal process conditions violations, planned preventive maintenance insufficient quality, etc. Process units’ incomplete loading, caused by a change in the raw materials consumption structure at enterprises, leads to a change in the equipment loading regimes and the increase in its stops. To a greater extent, this refers to the process pipelines linking the reactor equipment, which has a no stationary change in the stress state. In this connection, it became necessary to develop a method for determining the process piping movement when the reactor axis misaligns from the vertical. The process piping deformation calculating results verification in the reactor axis misalignment from the vertical obtained in the SOLID WORKS software package and their comparison with the results of the reactor prototype mock-up with process piping were performed in this work. Ultimately, this allows creating a unified approach to the various factors influence study on the reactor pipeline systems, which is an important task that contributes to improving reliability and trouble-free operation. The estimation of deformation displacement piping axis deviation from the vertical reactor standard, numerical and observational methods, the comparative analysis of the results obtained.

MODELING THE STRESS STATE OF HARD TISSUES OF A TOOTH IN THE PROCESS OF RESTORATION OF CLASS I CARIOUS CAVITIES

To study the stress state of geometrically complex multilayered bio-mechanical system consisting of enamel, dentin and filling, the three-dimensional solid modeling in the SolidWorks software package and mathematical analysis with finite element methods in the ANSYS Workbench program were used in the research. In the mimicking, the tooth is seen as an elastically deformable body under static loading of evenly distributed force. It is found that the inner stress in the hard tissue of intact tooth is maximum (74.2 MPa) in the area of application of the load. The maximum stress (119 MPa) in a restored over the I class carious cavity tooth occurs in the area of enamel contact with the restoration.

Errors in different geometric aspects of common engineering parts during rapid prototyping using a Z Corp 3D printer

The aim of this paper is to analyse dimensional errors and repeatability of commonly used engineering parts, including a metric bolt, a gear and a shaft, produced by rapid prototyping. The parts were designed by a SolidWorks software package and printed by a ZPrinter 450 from Z Corporation where ZP150 powder and ZBond 90 infiltration were used. In most cases, the dimensional errors on produced parts were within acceptable limits. However, the process was determined to be unsuitable for features requiring very high dimensional accuracy and good surface finish. The influence of the stacking effect on the parts became significant in the case of longer parts and was proportional to the z axis dimension of a part. The accuracy and repeatability of a produced part depended on the part’s orientation. Dimensions in the z axis direction showed very good repeatability, but the accuracy decreased with the increase of length. On the other hand, the repeatability in the xy plane was not as good compared to the accuracy in the same plane.
