- PublicaciónAcceso abiertoCalibración y puesta en marcha de un prototipo de máquina a flexión para el apoyo a la enseñanza aprendizaje de la mecánica de materiales(Universidad de Ibagué, 2018) Bautista Lozada, Jeissy Lizeth; Méndez Roa, Yury Andrea; Montoya Vallecilla, Jorge OlmedoIn this paper, we present the calibration results of a bending machine prototype, designed and constructed for bending beam failure, in accordance with the INV E 2012 regulation. In the calibration process, test beams of different flexural strengths were failed, both in the prototype and in the calibrated machine. From the resistance to compression of concrete cylinders after 7 and 14 days of curing, the cracking stresses of the obtained resistances were calculated and a comparative analysis was made with the crack modules obtained for the prototype and the calibrated machine. The results obtained indicate that the prototype shows values of cracking modules between 96% and 97% of those obtained with the calibrated machine and that it is therefore a good alternative at low cost for use as a support tool for teaching in the area of structures in the Civil engineering department of Universidad de Ibagué.

In the process, 14 and 28 days of curing specimens were used, and they were tested both in the prototype and in the calibrated machine. Based on the results obtained, the cracking stresees of tested specimens were calculated and a comparative analysis was made for the prototype and the calibrated machine. As a result, it was determined that the prototype indicates values between 97% and 98% of similarity compared to the calibrated machine. With the above it is concluded that the reliability of the results allows the prototype to be used as a support instrument for laboratory practices in Mechanics of Materials course.
- PublicaciónAcceso abiertoDiseño de infraestructura y elementos de mobiliario urbano de paraderos, para el sistema de transporte público de la ciudad de Ibagué(Universidad de Ibagué, 2019) Trujillo Manrique, Laura Marcela; Gómez Castaño, Carlos Fernando; Zuluaga, Juan GuillermoThe bus stops are part of the movable infrastructure, which is an influential factor in the operation of the Public Public Transport service (TPC), since it is there where the safe ascent and descent of the passengers is made, therefore, it is important that these stops are comfortable and safe to exercise the waiting time while the bus arrives. Most of the furniture in Ibagué is little used by the users of the system, because there is a perception of insecurity in these places and the vandalism has meant that they are not in good condition to provide the service. The objective of this research is to design the infrastructure and elements of the urban furniture of the public transportation system in the city of Ibagué, to offer the community a whereabouts able to operate optimally and provide a waiting time for the service more comfortable, promoting the use of these and thus increasing citizen culture, road safety and contributing to the correct mobility of the Tolima Capital. In the work we identify the characteristics and design criteria that users would expect to have in a bus stop, in order to achieve a more pleasant and useful waiting time, characteristics that are taken into account in order to carry out two designs where, through surveys of the users, the level of acceptance was evaluated for the selection of the final design, obtaining a 54% acceptance for the selected whereabouts.
- PublicaciónAcceso abiertoDiseño de la ruta óptima de regulación de válvulas de la red de distribución de tanques del Ibal en la ciudad de Ibagué(Universidad de Ibagué., 2019) Morales Mafla, Emanuel; Orjuela, Andrés Felipe; Casas Guerra, Mario AlbertoThe IBAL is the company in charge of supplying drinking water in the city of Ibagué. In order to fulfill this mission, a series of processes must be fulfilled. The process of valve regulation consists of preserving a control of the water pressure generated by the water. tanks and maintain a stable water level for the continuous supply of potable water to the sectors, this process is carried out daily in 5 different tanks located in the city of Ibagué, reason why the operator must be transported in a vehicle to all these points . In order to improve the valve regulation process by reducing transport times, an optimization of the routing is generated, as well as a time study generating a standardization of the execution times of the operation, developing a control of the process .

- PublicaciónRestringidoLímites de aceptación para las unidades de producto terminado según sea la capacidad del proceso en Diana Corporación S.A.S.(Universidad de Ibagué, 2018) Cote Hernández, Juan José; Osorio Niño, María CamilaIn the production plant of Diana Corporación S.A.S. in the municipality of El Espinal in the department of Tolima, the Diana brand rice is produced. For the company it is important that its finished product complies with the established quality standards. The percentage of broken grain that the units of finished product possess is the most important quality characteristic because it is this one that gives the commercial value to the product. For this reason a capacity analysis study was carried out to determine the specification limits that must be had for Diana brand rice, taking into account the quantity of accepted units, since if quality policies are not complied with, spaces can be generated for potential sanctions and the legal requirements and customer satisfaction are notoriously affected. The development of the work was carried out in 2 hoppers of the packing area with different design; these hoppers handle a flow of channeled type which is not recommended for the process they handle. The study was performed 3 times on each hopper, where approximately 32 samples of finished product were taken and 8 during the filling of each hopper. These samples were taken to the laboratory of the production plant to determine the percentage of broken grain that had one, these data were recorded in a format that was created during the collection of samples. It began by using Shewhart's control charts to verify that the data collected was under statistical control, the charts were used with control limits of ±3σ. Those data which exceeded the control limits were removed from the study and an analysis was performed describing the actions taken during the collection and analysis of that sample. After verifying that the data were under statistical control, a series of hypothesis tests were carried out to determine if the replicas made of each hopper were statistically similar in mean and in mean. In the case of a deviation, it was found that one of the replicas did not coincide statistically with the other replicas, so this one was considered a separate hopper. Those hoppers that were statistically similar in mean and deviation were joined together to create a single control chart, perform a general capacity analysis and be able to determine the acceptance limits for Diana brand rice. These were taken into account at the time of carrying out the capacity analysis, because one requirement for this analysis is that the data behave normally. In such a case, if they were not normal, a goodness of fit test had to be carried out to identify the type of distribution of the data, the data of the replicas had a normal distribution but at the moment of joining the replicas that were statistically similar and performing the normality test again it was found that the data did not follow a normal distribution, these data were transformed by means of the Box-Cox transformation. Finally, a capacity analysis was performed on each hopper studied and on the union of the replicas that statistically coincided in mean and deviation, it was verified that none of these gave acceptable results in the capacity analysis. It was necessary to identify the intervals of tolerance, these intervals had to comply with a minimum of accepted units, after having the intervals of tolerance the analysis of capacity was carried out again only for the union of the replicas to determine if these intervals were acceptable for the finished product. It was concluded that the limits of acceptance of percentage of split grain that were determined increased the number of units accepted in its process but decreased the demand on the quality of the product, that is why it was recommended to Diana Corporación S.A.S to change the design of the packaging hoppers for a design with mass flow and to carry out the study again, since with the current design it is not possible to meet the quality requirements.
