    Diseño de un generador de flujo para un dispositivo de asistencia respiratoria de presión positiva de dos niveles (BIPAP)
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Bayas Altamirano, Josue Edmundo; Núñez Núñez, Diego Fernando
    Nowadays, the need for medical equipment for the treatment of respiratory diseases is growing more and more and the state’s expenditure for the acquisition of the same is very large, so the objective of designing the flow generator of the respiratory assistance devices such as BiPAP; opens the way to be able to manufacture ours at national level thus reducing the budget for the acquisition of these. The Technical Project focused on the design of the generator under conventional parameters of operation, this implies the development of the flow system and the control system in charge of supplying positive pressure with a driver of speed variation of the centrifugal ventilator together with a programmable control board, for the configuration of the treatment that the patient needs; the selection of the manufacturing materials and elements necessary for its operation was carried out. The behavior of the flow generator was analyzed by means of a multiphysical computational analysis, this was very useful since it allowed us to establish the operating range of the device, for the development of the manufacturing and assembly process. As a result, a virtual mock-up was created with all the information about the design process, including all the parameters contemplated in the design process of the flow generator, simulation results, manufacturing drawings and assembly drawings. Resulting in a solid project that is ready to be put into test operation.

    Diseño y construcción del utillaje para el método estándar de prueba para propiedades de compresión de polímeros (ASTM D695:2015) en el centro de fomento productivo metalmecánico carrocero
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2020-10) Valle Yépez, Miguel Sebastian; Espín Lagos, Segundo Manuel
    Through the following technical project, polymer tests to be carried out at the CFPMC were increased. With the necessary research and following the specifications of the ASTM D695: 2015 standard. The objective that was fulfilled in this technical project was the design and construction of the tools for the standard method of polymer compression tests (ASTM D695: 2015). With the information obtained, the material, the design with adequate sizing, the dimensional relationship according to the accessories, the main parts and the construction characteristics for the manufacturing were determined. Finding the separation margins between parts, tolerances and surface finishes for optimal assembly. The documentation was created under NTE INEN ISO 17025: 2018. Performing tool validation tests with ASA and PLA polymers with 3D printing specimens. It was concluded that with the selection of AISI D2 material it is guaranteed that the tooling will support the maximum load that is 50 kN, producing a maximum deformation of 0.0039 mm. It was also found that the tooling complies with the provisions of section 5.3 of ASTM D695 which states that the construction of the tool must be such that the axial load is applied across surfaces that are flat and parallel to each other. , in a plane normal to the vertical load axis. Good results were obtained in the compressive strength of the polymers used, obtaining a value of 67,236 MPa for the PLA polymer and a value of 37,666 MPa for the ASA polymer.

    Diseño y construcción de una canasta de elevación para una persona en el interior de la cabina de pintura de autobuses para la Fábrica MIRAL Autobuses
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2019) Yansapanta Pilamunga, Alex Ermel; Arroba Arroba, César Hernán
    The project present was developed in the city of Ambato in the factory "MIRAL BUS", the interest in the factory for the construction of this lifting basket for a person inside the cabin lies in the need to facilitate the process of painting the buses in this way improve the production line of the factory. For the design of the lifting basket a statistical study was carried out, where the maximum weight of the person designated for the painting process to the bus was determined, the basket was raised together with the person using a manual key. The General System of Translating and Lifting consists of the following mechanisms: upper and lower horizontal translation systems, the system of the lifting guide rails, the support structure for the lifting basket and the lifting basket, for the design of the various elements of each mechanism, mechanical design statements are used to resist the loads and stresses that occur in them. A gearmotor was selected for the respective operation of the General System, it´s that moves along the bus. The construction and assembly of the General System was carried out in the facilities of the factory using the economic, material and human resources of the same. The assembly of the General System, where the lifting basket is a part, was developed inside the paint booth of the factory to proceed with its correct operation to elevate and move the person along the bus.
