- ÍtemAnálisis de falla a un perno de sujeción de una peletizadora(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Pedraza Arias, Jairo Alexander; Gutiérrez Bernal, Jesús ManuelThe project of degree Analysis of the failure of a bolt to hold a pelletizer is a diagnosis of causes and effects of faults that occur in components that work in a pelletizer, in this case, the bolt that holds the blades of the pelletizer. To reach this end, an initial observation of the components was made, a detailed analysis of the elements through metallographic studies and hardness tests. By compiling the results obtained, the data obtained by means of specialized bibliography is deepened, in order to make a correct diagnosis of the faults. After analyzing the data, it is concluded that the components fail mainly due to bad operation of the boiler, which does not work with the appropriate parameters. In addition to this, the welding application in the joints is not the most correct, which also plays an important role in the root cause of the faults present.
- ÍtemAnálisis de falla por fatiga de un resorte helicoidalDaza Hernández, Luis David; Clavijo Velásquez, Luis Ariel; Gutiérrez Bernal, Jesús ManuelThe present project was carried out a failure analysis in a coil spring of a Chevrolet sail vehicle. The first thing that was done was a visual inspection and identification of the possible faults that this could present, in this way the practical tests were started which were carried out in the laboratory where the helical spring was mounted. In a 4 HZ® mechanical cycler, to know the cycles it supports before failing, the process is then performed to know the microstructure of the material, which indicates stunned martensite. Followed with the phases of the project was made the 5 hardness traces in HRC with different depth%. In which it was obtained that in the 0.02mm trace it gives a hardness of 51.00 HRC, that of 0.04mm of 51.00 HRC without showing any variation. In the third and fourth shot shows a small variation of 05 HRC, giving the following data equal, the 06.00mm footprint gives a hardness of 51.50 HRC and 0.08mm of 51.50 HRC. Likewise, the last shot that gives in the center of the material gives a little harder. The 0.10mm trace gives a hardness of 52.00 HRC, after the 5 marks are taken, the 5 results are added and we divide them into 5 to obtain the average of the real hardness.
- ÍtemAnalisis metalografico de probetas obtenidas a partir de un proceso de manufactura aditiva por soldadura por arco (WAAM)(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Ramírez Martínez, Omar Felipe; Corrales Rojas, William Yesid; Gutiérrez Bernal, Jesús Manuel; Hincapié Campos, Williams Steve (Codirector)The following document presents a metallographic analysis of several strands of two specimens obtained by wire arc additive manufacturing (WAAM) for Foundation University the Liberators. The samples obtained by this process were subjected to a preparation process under the standard practice for the preparation, cleaning, and evaluation of corrosion test specimens (ASTM G1), after which the specimens were left with a gloss-mirror finish with the help of a cloth of fine fibers, then, a chemical attack was performed with 3% Nital to reveal its metallographic structure. As a result of the chemical attack, a structural recognition was made using a metallographic microscope (Olympus GX41) which provided us with great information when studying each weld bead, allowing us to identify its metallographic structure in each of the trajectories of the weld bead; Finally, a micro hardness test was carried out using the Future-Tech FM-700 micro hardness tester with a load of 100G with a result in Vickers (HV) in each of the beads, and thus being able to find the differences in microstructure and hardness between each weld bead, which will be shown in the following tables.

- ÍtemDesarrollo de un simulador de manufactura aditiva por soldadura por arco (WAAM) para el centro de mecanizado Leadwell V20i de la Fundación Universitaria Los Libertadores(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Poveda Castillo, Yeimy Caterine; García Zaragoza, Ubaldo; Gutiérrez Bernal, Jesús ManuelAdditive manufacturing, for its ability to create three-dimensional parts, providing flexibility, structural integrity and geometric resolution, similar to other conventional manufacturing processes; is positioned among a list of 15 disruptive technologies that achieve relevant change and disrupts the way industries, businesses and consumers operate. This document presents the development of an additive arc welding manufacturing simulator (WAAM) for the Leadwell V20i machining center of the Los Libertadores University Foundation with the help of SprutCAM software. The objective is to strengthen capacities in terms of research, laboratory equipment, and personnel training, providing the students of the institution the possibility of generating autonomy in the manufacture of metal components. Using the methodological approach used, the theoretical parameters on the state of the art of additive manufacturing in specific with arc welding were initially reviewed, allowing a positive approach to the implementation of this technology. The main contributions of the research are framed in the integration of a Lincoln SPEEDTECCC 200C welding equipment to the Leadwell V20i machining center to generate a dual purpose machine which are: subtractive and additive technique, as well as the development of a simulator with the desired parameters that allows to have a preview to the print, resulting in the development of a working methodology that allows the automatic manufacture of parts through the WAAM process and finally an approach to the process from the perspective of non-destructive testing.

- ÍtemDiseño de un sistema de extracción mecánico de humos producto de un incendio en el atrio ubicado en la sede Bolívar de la Fundación Universitaria Los LibertadoresAlba Torres, Julio Cesar; Gutiérrez Bernal, Jesús ManuelAutomatic sprinklers are the system that has saved most lives in incidents with fires, but it has been determined that the sprinklers are not effective after a certain height like the one found is in a atrium In the atriums the ability of sprinklers to extinguish fires in spaces with ceilings with heights between 9.1 and 15.2 m is limited. Because the temperature Reduction of roof height (due to drag of ambient air), the smoke may not be hot enough to activate this function on the roof of an atrium (Klote, 1994), this is the which is why it is important to implement an extraction system smoke mechanic in an atrium where the main objective is to maintain a smoke-free environment as long as possible to guarantee a time of sufficient evacuation and a smoke-free environment for firefighters or the Emergency team make fire control without compromising your safety.
