The present research consists in the application of statistical tools for the monitoring of the energy efficiency of indicators in productive processes that comply with the requirements of ISO 50001:2011. This paper presents the methodology and the results in terms of forecasting (SGE) for the consumption of electric energy in the manufacture of H-10 blocks using the STATGRAPHICS Centurion XV Software. The outcomes demonstrated the stabilization of the energy efficiency associated with an increase of production without investment by purchasing new equipment. That is to say, that only with the innovation and the follow-up of the process through applied management technologies the resources of the company can beoptimized, besides the adoption of a culture of energy management in an efficient way. The energy efficiency is optimized taking into account all the variables that influence the production process, besides performing preventive maintenance of the equipment in order to stabilize and control theparameters involved in the manufacture of masonry products for construction.

El sistema de frenado de un automóvil debe satisfacer un conjunto complejo de requerimientos, siendo la seguridad lo más importante. En el diseño de estos sistemas, influye directamente una correcta geometría y una selección adecuada del material para garantizar su correcto funcionamiento. El objetivo de este trabajo, es proponer un nuevo arreglo geométrico para la optimización del flujo de aire en un disco de freno automotriz, teniendo en cuenta pilares de ventilación fundamentado en perfiles aerodinámicos tipo N-38. Para validar esta propuesta de diseño, fue construido un prototipo a escala 1:1 por medio de manufactura aditiva y de esta manera poder medir el campo de velocidades generado en la zona de succión y descarga utilizando Velocimetría por Imágenes de Partícula (VIP). El arreglo geométrico se llevó a cabo bajo dos condiciones de velocidad angular: 541 y 941 rpm. Los resultados obtenidos muestran la optimización de la velocidad del aire en la zona de descarga de 0.2121 y 0.743 m/s respectivamente para los rangos de velocidades; con lo que se evidencio la importancia de diseños experimentales con los cuales se pueda mejorar la geometría de los frenos de disco autoventilados y de esta manera garantizar la eficiencia y seguridad del sistema.

The present study about ternary diagrams of SiO2-Al2O3-K2O has been conducted from the determination of two possible optimal clay mixtures through hydrometric tests of a company dedicated to the manufacture of masonry products for construction in the North region of Santander in Colombia; this work is the continuation of others carried out previously. In this raw material (clay) the dominant minerals are silica, alumina, iron, potassium, among others, which provide the plasticity and adequate granulometric distribution. Two optimal m7 and m8 mixtures were selected from 5 samples (M1, M2, M3, M4 and M5) of clays from different points of the company’s mine, these mixtures were analyzed by Fluorescence and X-ray diffraction tests with the purpose of determining the chemical elements in their maximum percentage and to be able to graph them in ternary diagrams with the help of FACTSAGE software and finally determine their cooking behavior. The results of the investigation showed that the physical characterization of the clays provides a broad view on the technological behavior of the raw material and consequently the quality of the final product.

The objective of this work was to design a milk “Panelitas” molding machine, which can provide process technification and quality of life of workers of this industrial sector, which will achieve higher production and thus guarantee an inventory of the products elaborate handmade using methodologies and theories of design. Finally, the results calculated mathematically are supported by the finite element analysis that corroborates the excellent performance of the material selected for the machine, specifically the hopper, which is the most important element. In anything case, the materials exceed the mechanical properties of the material and element selected under the real operation conditions.

Purpose The braking system on motorcycles is of vital importance, taking into account that its operation is based on the friction between the surfaces in the contact that are found heat and, therefore, the brake liquid, the thermoelastic deformation on the contact surface, the degradation and failure of the material, as can be attributed to the safety of the occupants. The purpose of this paper is to perform mathematical calculations regarding the phenomena of the transfer of heat generated in the brake system. Design/methodology/approach Using SolidWorks simulation software, the geometric model of the three disc brakes of the different cylinders was carried out to identify the elements with the variations of the maximum temperature, and the verification with the calculations was made under ideal condition (80 Km/h and 12°C). Findings The results obtained show that with the mathematical calculations it was possible to validate the correct functioning of the braking system under different operating conditions, the systems that have higher capacity of displacement generate higher heat loss at higher speed so that their time of cooling according to Newton is major. Originality/value Through the analysis of finite elements, it was possible to identify that the braking system in severe working conditions is not overheated, assuring a natural convection cooling in approximately 12 min according to the mathematical calculations made.
