Abstract
This study aims to present the results of a particular automotive component, called Engine Bracket, subjected to Topology Optimization to find the most suitable mass distribution of material, according to a geometry defined in the project and working conditions for this component. Topological Optimization is a technique that aims to find the best mass distribution within a predetermined volume of the component that is subject to a single load or multiple loads. The Engine Suspension is formed by the powertrain assembly and the anchoring brackets thereof with vehicle body. The powertrain subsystem is the component responsible for powering the wheels of the vehicle. The engines brackets are the elements which the powertrain is installed on the body. They must comply with the assignment of resisting the possible cases of loadings generated by the engine running on them (and consequent fatigue), restrict the movement of the powertrain for not occur contact between any component of the engine compartment, filtering vibrations generated by the engine in its varied operating conditions, among other functions. In this work, as a goal for the optimization, it was proposed to minimization of mass distributed in the pre-established volume, restricting the resulting Maximum Main Stress, given a most severe case of load in which the assembly was submitted. The result of the Topological Optimization, showed regions within the volume predicted on the Engine Bracket in which there is a need to fill material, contributing considerably to the design of the final geometry of the component.
