Use of Bézier curves in the design of the displacement law of the cam-follower mechanism: Von Mises effective Stress

Acevedo Peñaloza, Carlos Humberto; Ramón Ramón, Sergio Andrés; Bustos Urbano, Víctor Jhoel (Revista UIS IngenieríasColombia, 2020-07-01)

Designing cams by Bézier Curves has become increasingly common, since the mathematical development of this method is less complex. Bezier curves are Bernstein-based polynomials under a unitary domain, and in that sense, ...

Martinez Yanez, Daniela | 2018-11-29

The article presents the design and development of filters (easy to implement in homes) that have the capacity to eliminate microorganisms and chemical substances; therefore, they act as handmade water purifiers. It constitutes a reasonable alternative solution to the problem of contaminated water consumption, which can be applied in places of low economic resources.

Delgado Ruiz, Leonardo | 2018

This article presents the development of some case studies on shell and tube heat exchangers using a graphical interface developed in MATLAB®. Through the case studies, the variation in the performance of the equipment was determined by means of the heat transfer coefficient in function of some parameters such as mass flow and tube arrangements, establishing initial conditions for each run that were established in the software. Likewise, the article shows in detail the methodology with which the study was developed, the fundamental equations used to calculate these results and the graphs obtained. Through this study, it was verified that the variables studied had such an influence on the parameters evaluated, with the objective of establishing selection and operation criteria when designing a shell and tube heat exchanger.

The research has been dedicated to the study of the calculation of the stresses and design conditions given by the safety factor of operation of the structural members of the mines that use wood as their main support material. Wood is a lightweight material, easily transportable and easily handled in ademe systems [1]. For this case, the structural member that is analyzed is the union between the column and the beam of the mine doors, known as the German door. For the development of the study, the geometry of standard doors commonly found in coal mining has been taken into account. The reason for the research on the proposed topic stems from the need to have a secure control over the structural sustainability of the mines, since the use and possible deterioration of the wood under operating conditions and in the mining environment is very important for human safety.

Castro Duque, Yesid | 2018-10-18

The article presents the results of the heat transfer analysis that is generated in an underground environment, specifically in coal mines. The objective is to observe the variability of the results, comparing mines with level access and inclined access; Another parameter of comparison has been the variation of the altitude at which the mines are located; The parameters of temperatures, air flow, relative humidity, air density, length of roads, quantity of explosive, number of miners, etc., have been collected in a coal mine located in the city of Cúcuta - Colombia. In order to speed up its use, it has used its own development software, which serves to model comfort and environmental quality underground.

Use of Bézier curves in the design of the displacement law of the cam-follower mechanism: Von Mises effective Stress
...
Acevedo Peñaloza, Carlos Humberto | 2020-07-01

Designing cams by Bézier Curves has become increasingly common, since the mathematical development of this method is less complex. Bezier curves are Bernstein-based polynomials under a unitary domain, and in that sense, this article presents the design of a cam using Bezier curves of degrees 5, 7 and 9. And beyond, this article seeks to show the variation of the effective effort of Von Mises in a cam-follower mechanism composed of a disc cam and a roller follower with translation movement and force closure. The expressions that allow determining the variation of Von Mises' effort for each of the curves used are presented. This variation is presented by means of graphs in which it is observed that as the degree of the curve increases, the magnitude of the efforts is greater, and this increases the probability of failure in the mechanisms. In addition, it was found that there is an inverse relationship between the stress and the radius of the primary circle of the cam.
