Performs the mapping of the previous state and after digitization. Describes how the digital program implementation process occurred. Identifies the benefits that have arisen from changes in the process. Check the benefits of digitization for engineering. In addition, it identifies design challenges. Regarding the nature of the research, it was opted for the applied research due to the practical disposition, being exploratory, since it aimed to clarify the process of digitization of the program of ideas. A qualitative analysis of the data was performed, aiming at the description and understanding of the theme studied. The method was defined as a case study in order to explore the theme in its real context, using a single case for an in-depth study. The place chosen for the development of the research was a company in the field of agricultural machinery located in the metropolitan region of Porto Alegre with about 1000 employees. The company was chosen for the case study because it went through a process of digitizing the ideas program in 2020. As an instrument for data collection, semi-structured interviews were used, and interviews guided by a script with open questions were conducted, allowing the interviewee to add different information in order to enrich the research. Regarding data analysis, the content analysis technique was used, performing a pre-analysis, exploration of the material and treatment of the results. As main results, it was highlight the improvement and reduction of the flow of idea capture, the digitization of the program database, the creation of a visual flowchart with real time access and the increase of ideas after the implementation of the digital solution.

Their thermal energy storage occurs through latent heat during the phase change process. Therefore, they can be widely used in heat exchangers, since the thermal exchange that occurs in this process allows the solidification and/or fusion process of materials depending on their temperature. In this essay, a numerical study of the fusion process of the PCM RT - 82 contained in an elliptical multiple tube heat exchanger is performed. This condition is analyzed by varying the geometric conditions of the tubes, the vertical eccentricity of the tubes in relation to the PCM rings and their orientation. The analysis is conducted by using CFD (Computational Fluid Dynamics) on the FLUENT software. The problem presented is two-dimensional, vertically symmetric and transient. The mathematical model is composed of the equations for the conservation of mass, energy and momentum. The numerical model is validated with experimental and numerical results from the literature. The results for total melting time, liquid fraction as well as liquid fraction and velocity fields are presented. The results show that among the geometric variations carried out in the study, the factor that most influences the reduction of the total melting time of the PCM is the tube eccentricity.

From prototypes to functional parts, we are experiencing a shift of the production style, the popularly called “3D Printer” is taking over industries and changing long-lasting concepts. Additive manufacturing offers a big advantage to segments like aviation, where projects last for decades and the weight of a part directly influences the performance of the plane. The possibility to produce organic shapes with ease and to maintain zero stock police, keeping the files and the 3D Printer ready to produce a part on demand, is extremely attractive to this segment. One of the key components present in practically all 3D printers is the material extrusion cooler, which helps to ensure dimensional accuracy as well as improving the finish aspect of the part, but it may end up impacting the mechanical properties of the final part. The study was carried out by making specimens, according to ASTM D636, in PLA and PETG and changing the rate of the cooler for each specimen. With the performance of tensile strength tests, the difference in the yield strength in the area where two layers bond together was determined. With the results, a graphic was elaborated showing the correlation between the cooler speed vs the yield strength. Finally, it was tested whether the behavior is repeated when utilizing materials from another manufacturer. The impact in the yield strength in the bond between layers suffered a reduction greater than 40%, when compared to printed specimens with the cooler turned off. This finding shows that for parts manufactured in order to resist stresses, the best practice is to use the cooler turned off during printing.

Este trabalho tem o objetivo elaborar um estudo de adequação, perante a legislação vigente, de uma máquina impressora de rótulos de latas de alumínio, de uma fabricante de latas, tornando o equipamento seguro de operar e assim evitar acidentes aos operadores, utilizando a metodologia HRN antes e após a adequação de segurança com base na NR-12. Este trabalho servirá de ferramenta para análise e adequação de equipamentos similares, visando a operação segura, diminuído o índice de acidentes com morte e afastamentos de trabalhadores de suas funções, causando danos financeiros ao empregador e previdência social.

The main features of this technology are: its use in waters below 5 to 15 m, without the need for accumulation reservoir and less aggressiveness in the environment, because its geometry and operating resources use the passage of fish through the turbine channel. Thus, the objective of this work is to construct a laboratory scale prototype of an Archimedes turbine and study the effects of leakage variation on an efficiency model, the range at which it performs best, and the relationship of leakage and velocity tests of rotation at the same yield. An estimated methodology use of design and manufacturing tools for prototype construction and screw testing at a 27 ° inclination with horizontal plane. As leaks from selected experiments from 21% to 185% of the nominal design leakage, where torsion filters were collected in different torques generated from the use of the drive axle braking system, with a friction and counterweight element with Prony brake assistance, and using tracking through the digital photo tachometer. The results show the versatility of the technology since the prototype is efficient over a range of 53% to 115% of nominal leakage, has rotational performance for leakage ranges and indicates leakage and related statistics directly over a range of 84 to 149% of the project leak.
