    Modelo de material para perfiles conformados en frío de sección transversal UV de acero a572, para espesores de 6 mm y 8 mm
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Muzo Chico, Danny Alejandro; Córdova Acosta, Christian Alexander; Peña Jordán, Francisco Agustín
    There is a notable deficiency in accurate data and analysis concerning thick-walled structural sections, particularly those of the UV cross-section. There are studies on thin-walled cold-formed steels, there is a gap in structural engineering knowledge due to the lack of studies performed in the thick-walled environment and the lack of material models specifically designed for cold-formed UV cross-sections using A572 steel. The experimental work started using the cold forming process of a structural profile of UV cross section of ASTM A572 gr 50 steel with thicknesses of 6 mm and 8 mm, which by water jet cutting, standardized specimens were extracted to perform tensile, micrographic and hardness tests, which are performed under ASTM E8, ASTM E112, ASTM E18 standards, respectively. Data were collected from each test and their mechanical behavior was analyzed. Several comparisons were made between the results of curved specimens and flat specimens of each thickness, thus identifying the variations in their mechanical properties. The hardness tests indicate the zone of affectation being 1.6t, in addition to the affectation of the cold forming process. As a result, the tests performed yielded data on the microstructural behavior of ASTM A572 steel in the cold forming process, as well as its mechanical properties, which will be useful for the support of technical reports.

    Diseño e implementación de un sistema fotovoltaico para el suministro parcial de energía de la unidad educativa Huachi Grande
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2023-08) Tonato Palomo, Denisse Anabel; Tutin Chicaiza, Riquelme Estefania; Mayorga Pardo, Alex Santiago
    This technical project was applied in the Huachi Grande Educational Unit of the city of Ambato in order to provide electricity to the administrative area, since there is no good infrastructure design, so it does not have enough spaces for the entry of natural lighting, in addition, the electrical wiring is in poor condition as there are no short circuits in some areas of the institution, causing them to run out of electricity on several occasions. For this project, the necessary components for the installation will be selected taking into account different design parameters such as the calculation of the energy demand of the 15 bulb-shaped luminaires, which is the basis for subsequent calculations. Using alternative selection tables, the specific components for the photovoltaic installation were chosen. With the components already selected, the photovoltaic installation is carried out in the institution to supply energy to the established areas. Finally, performance tests were carried out on 2 specific days: sunny, cloudy and at night, with a certain load value. Under these conditions, the voltage and current intensity at the input and output of the solar inverter were measured, obtaining the behavior of battery consumption and ensuring that the photovoltaic system is working correctly.

    Diseño y construcción de un acoplamiento mecánico del generador integrado al motor 3W-85cc para la alimentación del sistema eléctrico de los prototipos UAV en el centro de investigación y desarrollo de la Fuerza Aérea Ecuatoriana
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2019) Manobanda Tonato, Gabriela Elizabeth; López López, Germánico Adán
    The present technical project was based on the study, design and construction of: a galvanized steel support plate, in addition to pulleys coupled to the motor shaft, which work by means of a belt transmission system, all these components are integrated to the 3w motor -85 xi, we also proceeded to the selection of the components for the power supply of the unmanned aerial vehicles of the CIDFAE, using the test bench duly implemented with aeromodelling equipment such as AC / DC converter, battery YTX9 - BS IGEL 12V, DC / DC converter, sending the signal through the Futaba r6014Hs receiver, and feeding the Futaba s3305 servos these equipment are correctly installed and controlled through a radio control managed by the corresponding technician of the institution and under a technical order, with the development of this project it was possible to generate autonomous energy with around 30 amps and 12 volts, contributing to the greater flight autonomy of the prototypes.
