3D modelling, finite element analysis (FEA), and optimization techniques play a crucial role in the field of engineering. Each of these components contributes significantly to the design, analysis, and improvement of various structures and systems therefore enhances human life. The incorporation of these three tools method enables engineers to develop designs that are not only more efficient but also cost-effective. This methodology proves especially beneficial in industries like aerospace, automotive, civil engineering, and mechanical engineering, where intricate structures and systems demand comprehensive analysis and optimization to ensure successful implementation. As an University of Debrecen student studying in mechanical engineering specialization, I primarily decided choose these three combining methods as the main purpose of my thesis project:’ Generative design of track control arm’, component in a vehicle;s suspension system. In the early phase of the task, we will gather necessary resources which is related to a track control arm and 3D modelling software will be used in the thesis. In the first task, with the sketch is given and Solid Edge knowledge, a track control arm is designed. In the second task, the finite element model of the track control arm is established in the software, with the mesh generation and its material. Type of element is selected and boundary conditions and loads are verified. In the third task, by using the Solid Edge simulation, the module is analysed in different situations, the maximum and minimum nodes are reviewed and factors of safety are compared, therefore the range forced on the module is calculated. In the fourth task, the track control arm is optimized by generative design module of Solid Edge, achieved the new design and n, the design, simulation, and optimization process for the track control arm have yielded significant improvements. Through meticulous engineering and analysis, a remarkable 28% reduction in mass has been achieved and a new design released, contributing to enhanced overall vehicle performance and fuel efficiency. The incorporation of advanced simulation tools and optimization techniques has not only lightened the component but also led to the creation of a new, optimized shape. This achievement represents a commendable balance between structural integrity and weight reduction, showcasing the effectiveness of the design approach. The success of this project underscores the importance of employing cutting-edge design and simulation methodologies in the automotive industry. The 28% mass reduction not only aligns with contemporary trends in lightweighting for improved efficiency and sustainability but also positions the track control arm as a competitive component within the automotive market.
