    Diseño del proceso de manufactura del bastidor de un vehículo de competición GO KART aplicando técnicas de optimización
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Mecánica Mención Manufactura, 2021-01) Jácome Guevara, Fausto Andrés; Arroba Arroba, Cesar Hernán
    The present work aims to carry out the manufacturing process of a Go Kart chassis. Firstly, the design of the chassis is carried out in accordance with the regulations imposed by the CIK-FIA. The selection of the material is made by means of a previous choice of the three materials generally used in Ecuador for the manufacture of chassis, like ASTM A36, ASTM A 500 grade A and ASTM A1011. The analysis performed in the Ansys software shows that the best behavior to the applied stresses is the ASTM A1011 steel, so it is selected for the manufacture of the same. For the manufacture of the chassis, an efficient manufacturing process is designed in which the manufacturing time, costs and efficiency are taken into account by selecting the most suitable manufacturing processes for the elaboration of the frame, obtaining a functional, esthetic and economic structure.

    Optimización del perfil hidráulico de un rodete tipo Francis de la Central Hidroeléctrica San Francisco
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Mecánica Mención Manufactura, 2021-01) Núñez Villacís, Guido Santiago; Arroba Arroba, Cesar Hernán
    The research work is based on the bibliographic and field methodology, the research method used was experimental, to complete the optimization method, five experiments were carried out in which variations were made in its geometric dimensions, to execute a computational study Using computational fluid dynamics in the virtual laboratory of the CIRT turbine research and recovery center, the main study parameters were the thickness of the blade, as well as the fluid inlet and outlet angles in relation to the impeller, resulting in efficiency produced by the impeller in each of the experiments performed. With these experiments, it was possible to conclude that, by modifying to the opposite direction of the main inlet curvature of the blade, the efficiency value can be increased, reducing turbulence along the path of the fluid on the surface of the blade, which improves the hydrodynamic properties, thus lengthening the useful life of the turbine.
