The electric motor components will be designed parameterized to make more easily update when<br>the electric motor functional parameters will be modified. In other words, the purpose of the project<br>presented is reducing the design time and, at the same time, the costs, using the mix between two programs<br>having different structures.</p> Alexandru GHEORGHE, Eng ##submission.copyrightStatement## http://www.sorging.ro/jideg/index.php/jid/article/view/409 Sat, 16 Mar 2019 09:28:11 +0000 THE ROLE OF SIMULATION IN EVALUATING THE BEHAVIOUR OF AN ELASTIC COUPLING WITH FLEXIBLE METALLIC ELEMENTS http://www.sorging.ro/jideg/index.php/jid/article/view/410 <p>The paper presents the analysis of the elastic coupling with flexible elements, taking into<br>consideration the mechanical strength criterion in conditions of normal loading or torsion overload, with<br>and without misalignment, using finite element analysis, responding to multiple demands that are required<br>in coupling structure. There are presented the basic principles for applying the finite elements method: the<br>study of convergence at different mesh sizes, the loading scheme and boundary conditions for the flexible<br>element. Also, the paper presents several simulations to prove the behaviour and functionality of the<br>coupling for different operational scenarios: mechanical stress, buckling stability and modal analysis.</p> Daniel DOBRE, PhD.

In order to<br>accomplish this, the fluid is circulated between the primary components via the circuit piping. The working<br>fluid flow through the pipelines forming the system circuit represents a complex phenomenon influenced by<br>a series of changes specific to both the fluid medium and the parameters at which the flow is accomplished<br>represented by the working pressure, circulation velocity or temperature values within the system. The<br>change of these flow parameters is also made due to the ducts and orifices type through which the fluid is<br>forced to pass, resulting in a specific pressure drop due to the inertial forces and fluid viscosity. In this<br>paper are presented theoretical aspects regarding fluid flow through orifices of constant section, as well as<br>the numerical analysis performed on the virtual model for highlighting the specific flow parameters. The<br>obtained results are presented in terms of total pressure, fluid velocity and turbulences registered at the<br>analyzed fluid region being emphasized the fluid stream contraction during the orifice passage and the<br>fluid trend afterwards along the pipeline axis.</p> Fănel ȘCHEAUA, PhD.

Furthermore, it puts at disposal stylistic modules available to specialists, allowing the<br>development of computer usage even in pre-construction stages. This paper presents the main design steps<br>and the 3D representation of a car body using the design leading software, Catia V5. Two subassemblies<br>are considered, front part and passenger compartment. General considerations of surface generation in<br>automotive car body design are highlighted. Sketching modules were used in order to create the conceptual<br>sketch, in which the required geometries for the solids were drawn, the Part Design module, in which the<br>solid parts of the car body were made, the Assembly Design module, the module in which the car body<br>components were imported and assembled, the Sketch Tracer module, a module in which real-world scale<br>shots are imported to create a custom concept, and the Freestyle module, in which the 3D lines of the car<br>body were drawn, after which the areas for surface generation were filled.</p> Eduard Narcis COROLENCU, Eng, Nicușor BAROIU, PhD.

Regarding the comfort of the caravan, this is described in particular by<br>ergonomic factors and the functionality feature is highlighted from the functional structure of the caravan<br>and described by components.</p> Nicoleta VOINEAGU, Eng ##submission.copyrightStatement## http://www.sorging.ro/jideg/index.php/jid/article/view/412 Sat, 16 Mar 2019 14:09:00 +0000 LPG, ALTERNATIVE FUEL FOR INTERNAL COMBUSTION ENGINES http://www.sorging.ro/jideg/index.php/jid/article/view/411 <p>Due to increased pollution and economical challenges of our days, alternative fuels have become<br>one of the most important fields of research. There are many alternative fuels available today, but one with<br>the highest potential is the liquefied petroleum gas (LPG). Already, important steps have been made in<br>developing new technologies and infrastructure for the LPG market. This paper presents the main<br>characteristics and functionalities of LPG, as a more economical, energy efficient and eco-friendly fuel.<br>Also, a comprehensive review of various types of fuel systems have been prepared for better understanding<br>of operating conditions and advantages for a LPG fueled internal combustion engine.</p> Georgian Sergiu NEAGOIE, Eng, Ionel SIMION, PhD Eng ##submission.copyrightStatement## http://www.sorging.ro/jideg/index.php/jid/article/view/411 Sat, 16 Mar 2019 14:09:23 +0000
