The project for the design, construction and implementation of a test bench for the analysis of the efficiency of small-scale Kaplan hydraulic turbines arises from the need to take advantage of underutilized water resources in certain areas of the province. This test bench will be in the laboratory of the Civil and Mechanical Engineering faculty, allowing students to understand the operation of Kaplan turbines and their potential to generate electricity from water resources. During the process of building the test stand, significant challenges arose such as leaks in the system and excessive friction between the torque measurement shaft and the turbine. To address these irregularities, additional stopcocks were installed. One of these stopcocks controls the flow rate at the pump outlet, allowing precise experimental adjustments. The second stopcock regulates the pressure within the circuit before the water recirculates to the tank, monitored by a glycerin manometer to measure pressures between 0.5 and 2 PSI. Medical dynamometers strategically placed at the end of the shaft provided accurate torque measurements, revealing values between 0.5 and 1.5 Nm, validating the effectiveness of the mechanical design. After overcoming irregularities and optimizing the components, the test bench was successfully operated in function tests, meeting the established objectives by providing effective flow, pressure and torque measurements. This project represents a significant advance towards the use of renewable energies, making efficient use of local water resources for educational and engineering research purposes.

The manufacture of guitars today continues to be developed in a traditional way. The lack of study to generate machines that speed up manufacturing times have been the main factors for its production to be carried out manually. Furthermore, the paradigms of how guitars are made remain an obstacle to the implementation of technology. Through search and data collection methods, the parameters for construction were listed according to the needs presented by the guitar manufacturer. With design methods and calculations, a creative machine prototype was made that satisfies the listed parameters. The design was analyzed using specialized software and its functionality and resistance to the different forces and temperature conditions that act on each of its components were checked. For its construction, commercial materials and accessories within the province were used to provide an accessible product to manufacturers. Functional tests were carried out and the speed, temperature and pressure were regulated according to the type of wood with which the hoops are made. The prototype machine reduced the time spent bending and gluing guitar sides to covers. In addition to reducing assembly times, it reduces failures and waste of raw materials. The machine demonstrates an important contribution in the manufacture of these instruments and paves the way for new innovation studies in this market.

The metalworking company INOX TEC located in Cunchibamba, in the province of Tungurahua, requires a beading machine for stainless steel sheets and tanks, to improve the properties of said material. It was proposed to design and build a hydraulic beading machine that can perform beading with thicknesses of up to 4 mm in AISI 304 stainless steel. The study was based on bibliographic sources and field studies, the feasibility of implementing the equipment was demonstrated. An efficient mechanical system was selected, appropriate to the productive capacity of the company to guarantee its economic viability, in the same way a hydraulic system was used to facilitate its use. Calculations, designs and machining processes were carried out, plans and computer simulations were prepared. Likewise, studies were carried out after the beading process where AISI 304 stainless steel significantly improves its properties, as well as its hardness and resistance. The hydraulic beading machine offers an ideal and fast solution through the use of a double-acting pneumatic cylinder that allows quick and efficient actuation at the time of beading, as well as a control center through which the process can be managed in a simple way. The materials used and the design of the equipment guarantee its longterm durability and efficiency. This project contributes to the well-being of the company and has the potential to be applied in other similar contexts if required.

Industrialization in Ecuador has been significantly driven by technological advances that benefit various industrial sectors. Among these, cargo vehicles play a crucial role in commercialization, generating a high demand for specific components, such as springs. These mechanical elements are widely used across different industries, particularly in the automotive sector. However, in Ecuador, spring manufacturing processes are typically handmade and lack technical design criteria, making it difficult to meet the growing demand for precision and quality. In response to this challenge, a machine was designed and built for the manufacture of helical springs with inner diameters of 1/2 inch and 1 inch. The objective was to modernize the process and improve production efficiency. Appropriate design parameters were researched, engineering software was utilized for development, and unctional tests were conducted to validate the machine's performance. The study employed an applied methodology that included the selection of mechanical elements, comparisons with existing models, and technical calculations to ensure optimal safety factors. As a result, a machine was developed that can manufacture custom springs with precise measurements tailored to the requirements of the automotive sector, which represents the highest demand. The primary contribution of this project is its support for the growth of Ecuador’s industrial sector by introducing innovative technologies that enhance traditional manufacturing processes. Furthermore, it highlights the practical application of engineering knowledge to address real-world industrial challenges, fostering efficiency and development in the country’s manufacturing sector.

In this degree work, a seismic vulnerability study is carried out for two representative structures that constitute the typical occupation given to steel buildings constructed within the urban area of Ambato Canton. These buildings, according to the NEC-2015, are categorized as essential and special type structures respectively. As an initial part, a preliminary design check was performed using the design spectrum prepared according to the standard for this sector, where compliance was reviewed in terms of floor drifts, soft floor and torsion in plan. Subsequently, by means of a nonlinear pushover static analysis, the capacity of the structure and its performance level in the presence of moderate and extreme earthquakes were determined. Likewise, certain influences of the infill masonry used in this type of structures were determined, and finally, according to the performance obtained, a reinforcement was proposed through the use of concentric diagonals and energy dissipaters in order to improve their performance level and avoid their collapse.
