A importância das simulações computacionais na análise estrutural de discos de freios sólidos e ventilados

Abstract

The modern world demands better and more efficient solutions in the creation of vehicle devices. There is a growing search for gain in function and cost reduction when producing components such as brakes, for example. In this sense, computational methods collaborate to reduce the number of interactions within a project, since the creation of parts to structural and thermodynamic analysis. Thus, this work aims to utilize the theoretical knowledge applied in computer analysis, seeking to show the efficiency of using 3D CAD softwares for the mechanical engineer in order to produce brake discs. The design and analysis are done through SolidWorks software, where besides modeling the necessary parts, it will be used for the desired analyses, using the selected material properties, boundary conditions, loads along the structure, verifying von mises tensions, project safety coefficients and thermal behavior of commercial ventilated and solid discs selected for this work. The process consists of the union of theoretical knowledge applied to disk brakes using the Finite Element Method, where the braking mechanic analysis such as loads and hydraulic pressures will be applied to disk brakes designed in this program. The computational simulations are going to be runned through SolidWorks Simulation module and results will be analyzed and compared with the goal of helping the mechanical engineer to make the best decisions.
