“…The heat dissipation and the performance of ventilated disc brakes depend largely on the air flow over the surface and through the ventilation channels of the discs, which can be studied using computational fluid dynamics (CFD). The design software SolidWorks offers modules for CFD analysis (Chi, He, & Naterer, 2009;Klimenda, Soukup, & Kampo, 2016;Rajagopal, Ramachandran, James, & Gatlewar, 2014;Wu, Xiong, Hu, & Yuan, 2015).…”

The braking system of a car must meet several requirements, among which safety is the most important. It is also composed of a set of mechanical parts such as springs, different types of materials (Metallic and Non Metallic), gases and liquids. The brakes must work safely and predictably in all circumstances, which means having a stable level of friction, in any condition of temperature, humidity and salinity of the environment. For a correct design and operation of brake discs, it is necessary to consider different aspects, such as geometry, type of material, mechanical strength, maximum temperature, thermal deformation, cracking resistance, among others. Therefore, the main objective of this work is to analyze the dynamics and kinetics of the brake system from the pedal as the beginning of mathematical calculations to simulate the behavior and Analysis of Finite Elements (FEA), with the help of SolidWorks Simulation Software. The results show that the third brake disc works best in relation to the other two discs in their different working conditions such as speed and displacement in braking, concluding that depending on the geometry of the brake and the cooling channels these systems can be optimized that are of great importance for the automotive industry.Keywords: Dynamics, friction, FEA, CFD, disc brakes, automobile. RESUMENEl sistema de frenado de un automóvil debe satisfacer varios requerimientos, entre los cuales, la seguridad es el más importante. Además, está compuesto por un conjunto de piezas mecánicas tales como: resortes, diferentes tipos de materiales (Metálicos y No Metálicos), gases y líquidos. Los frenos deben trabajar en forma segura y predecible en cualquier circunstancia, lo cual implica disponer de un nivel estable de fricción en cualquier condición de temperatura, humedad y salinidad del medio ambiente. Para un correcto diseño y operación de los discos de freno, es necesario considerar diferentes aspectos, tales como la geometría, el tipo de material, la resistencia mecánica, la temperatura máxima, la deformación térmica, la resistencia al agrietamiento, entre otros. Por lo anterior, el principal objetivo de este trabajo es analizar la dinámica y la cinética del sistema de freno a partir del pedal como inicio de los cálculos matemáticos para simular el comportamiento en mediante el Análisis de Elementos Finitos (FEA), con la ayuda del Software SolidWorks Simulation. Los resultados demuestran que el disco de freno número tres funciona mejor con relación a los otros dos discos en sus diferentes condiciones de trabajo, como lo son velocidad y desplazamiento en frenado. Así, se concluye que dependiendo de la geometría del freno y de los canales de refrigeración, se pueden optimizar estos sistemas de gran importancia para la industria automotriz.

“…At the starting mechanical stage on ventilated disc brakes, it is vital to analyze thermic flows performance where it is possible to observe flow features and operation upon discs' surface, by always guaranteeing braking process effectiveness and heat dissipation through the surface and ventilation ducts. Thermic heat dissipation and ventilated disc brakes performance mainly depend on aerodynamic features of air-flow, through ventilation ducts and disc brake geometrical configurations, which are proved via design software implementation provided by Computational fluid dynamics (CFD) library, such as: SolidWorks Simulation or ANSYS (Chi;He;Naterer, 2009;Klimenda;Soukup;Kampo, 2016).…”

Braking systems are undoubtedly the most important component for road safety, since it determines the total or partial stop of a vehicle and, therefore, guarantees the physical integrity of passengers. Normally, the front brake discs and the remaining percentage absorb 70% of the kinetic energy produced within a vehicle by the rear brake discs, which tend to have the form of a drum brake. These systems benefit from friction to stop a moving vehicle, under the umbrella of hydraulic pressure that pushes the brake pads against the iron-cast disk. In this document, concepts of famous authors around the world on analysis and evaluation of brake discs are provided, which are carried out using a descriptive methodology and an estimation of the characteristics of the brake disc. The review is carried out in computer assisted design through several existing CAD software in the industry, as the main methodology applied to the development of certain research projects, where different geometric characteristics of the brake discs are considered, as well as problems related to wear and corrosion. This research project has shown that it is vital to incorporate existing computer assisted design software to predict performance, improve components and optimize the functionality of the brake system. In this way, road traffic safety and systems efficiency are achieved, which are a matter of great importance for the industry. It is vital to analyze brake systems through Finite Element Analysis (FEA), with the intention of achieving a broader vision of its performance, since the information collected reveals that the geometric characteristics of the brake and cooling ducts influence the heat dissipation. It depends on the form, the type of material and the application, the heat generated between the pad and the brake. Therefore, the heat is dissipated rapidly according to the analysis performed mathematically by the researchers, which are compared with the made in computer assisted design software.
