The present project was elaborated in some phases, first designing the geometry considering spaces and distribution of components, the selection of the material was very important considering some materials it was decided to build the floor of the interior, the front and back with galvanized structural steel pipe ASTM A-500 of (30x30x2) mm and the ceiling with tube (25x25x1.5) mm, based on these parameters it was needed a CAD / CAE software to visualize the design and the forms, the next phase was to calculate the states load that would be subject to the structure such as vertical loads, braking, acceleration, rotation, resistance to wind and torsion, with the values of the loads was proceeded to simulate with the help of the ANSYS student version program to obtain results of displacements, Von Misses effort and essential safety factors for the design. Finally, in the construction phase, the selected profiles were cut and welded using GMAW ER70S-6 welding, while the structure was assembled also the other subsystems accompanying the structure were assembled as suspension, propulsion and steering.Item Implementación del sistema de frenos para el prototipo de auto eléctrico BIPLAZA UTA-CIM17(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2018) Telenchana Quisintuña, Christian Andrés; Pérez Salinas, Cristian FabiánThe present technical work is based on the implementation of a braking system for the UTA CIM-17 two-seater electric car prototype. The same that arises from the need to look for an ecological, efficient means of transport and capable of adapting to the road needs of our city. In addition, to integrate two of the faculties of the Technical University of Ambato for the generation of this project, reinforcing the skills of teamwork and the adaptation of students to the world of work. For the realization of the present project, a study was made of the general parameters of the UTA CIM-17 two-seater electric car prototype as the total weight of the same, the maximum speed reached, the type of traction and space available for the installation of the system in the design of the vehicle, the same ones that were necessary for the design of a brake system and the adequate selection of the necessary components for it. Several proposals were analysed for the design of the braking system which were weighted in order to choose the most viable and efficient for the vehicle. With the system already defined, the system was implemented in the electric car to subsequently perform the respective operation tests and correct possible errors in the installation of the system; in addition, to collect information on the operation of the brake system in practice. Finally, a manual of use and maintenance was made necessary for the proper functioning of the brake system.Item Selección e implementación del sistema de dirección para el prototipo de auto eléctrico BIPLAZA UTA-CIM17(2018) Gallardo Tonato, Wilmer Omar; Pérez Salinas, Cristian FabiánThe purpose of this project is to design, select and implement a steering system for the electric car prototype UTA-CIM17, this project is very important for the Mechanical Engineering Career since it leads to the development of new technologies friendly to the environment and serves as a basis for future research related to this invention. For the fulfillment of the project, the parameters and criteria of design and selection were analyzed in order to form a system that provides safety, smoothness and maneuverability to the driver. Was selected a steering mechanism by means of pinion and rack of the Suzuki Forsa I, since it has low cost, a moderate weight and it was possible to modify its structure, cutting the steering terminals with the purpose of reducing the distance between ends so that it can be assembled in the suspension pivot, since being a prototype, its distance between wheels is very small. This change was very representative since it did not affect the functioning of the system. The steering column has two universal joints arranged along the axle with the aim of providing passive safety to the driver, which in case of collision will reduce the damage considerably. The axes of the steering column were designed using the formulas for the design of circular members subjected to torsion and constructed of Steel AISI 1018, because it has good mechanical properties, has low cost and is available in the national market. The steering wheel and the removable base of the steering wheel were selected analyzing their weight, their cost and their dimensions, thus achieving comfort in the driver and an ideal operation. Finally, different calculations were made such as: turning radius, turning angles of the wheels, necessary effort to turn the tires, convergence, angle of convergence and direction transmission ratio, which were checked with the regulation N ° 79 of the UNECE (United Nations Economic Commission for Europe), with general standards and with measurements of the final system, being able to verify that the project was carried out satisfactorily and complies with the technical standards for homologation.Item Diseño y selección del sistema de suspensión de un prototipo de auto eléctrico BIPLAZA UTA-CIM17(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2018) Mejía Mayorga, Esteban David; Reyes Pérez, Diego Fernando; Analuiza Maiza, Oscar IvánFor the realization of the technical project, effective alternatives were sought, to the need to obtain a suspension system for the prototype of two-seater electric car UTA-CIM 17, which meets the needs of the medium to circulate, where asphalted roads with speed breaks are presented and that they are at the forefront of the car market, in which, according to the weights applied to the vehicle, a McPherson type suspension is selected for front tires and a rigid type for rear tires. The displacement required by the suspension springs to provide safety, stability and comfort to the user was analyzed. Once the requirements were obtained, the actual behavior of the spring movement was compared and modified to achieve values close to those required. Analyzes were done in CAD software to verify the studies The specific parameters of mechanical elements were taken into account to the working conditions and the adaptability with the other systems that make up the car. Once finished with the design and construction of the suspension system, performance tests are performed, where the correct functioning of the system can be evidenced in critical conditions for the elements that make up the suspension system.Item Análisis aerodinámico de un prototipo de auto eléctrico BIPLAZA UTA CIM17(Universidad Técnica de Ambato.

Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2018) Naranjo Quispe, Lincol Marcelo; Jijón Arias, Héctor Leonardo; Paredes Salinas, Juan GilbertoFor the elaboration of the present technical project, the materials that comply with the applicable regulations, manufacturing processes and finishes suitable for the elaboration of the external and internal parts of the auto prototype were selected. In this technical work, the weighting was used as a selection tool for the different external and internal components that were used in the manufacture of the CIM17. The hybrid materials were taken into account for the interior lining process since some of these are within our reach, we can cite as an example the polyester resin + abaca fiber + cotton fiber, this being one of several materials that can find. Regarding manufacturing processes, manual stratification was used to obtain the piece made with the hybrid material that was used in the construction of internal components, as was the case with the board. The outer covering was made using the sheet metal technique to give shape to the design previously made, and also the components such as windows and windshields were built according to molds that were better adapted to the design of the CIM17.Item Diseño y construcción del sistema de propulsión para un prototipo de auto eléctrico BIPLAZA UTA-CIM17(Universidad Técnica de Ambato.
