[en] A goal of this project was do develop a new good-looking racing rim of a sport car which would be lighter than existing ones. To achieve the goal, lightweight magnesium ally Mg ZK60-T5 was applied for the rim and its preliminary shape was developed employing topology optimisation. The rim was designed for forging technology; this means that it had to have all manufacturing features required by that production process.
Basing on a literature review, loads, boundary conditions and structural requirements were estab-lished which were crucial for a farther development process.
The initial design was created by means of the topology optimisation and then a parametric model was developed using a CAD system. As a next step, a first part of validation were done employing FEA in order to meet strength and stiffness targets, some modifications of the CAD model were imposed. As the last step, the final validation was done by means of simply fatigue assessment. The optimisa-tion and FEA were completed using Hyperworks 14/ Inspire 2015 software and the CAD model em-ploying Autodesk Inventor 2015.
The results shows that the rim design meet theoretically all structural requirements and a good-looking shape was reached. Total mass of 7.9 kg of the designed rim is obtained, which means a re-duction about 1.8 kg with comparison with a reference rim. The 3D model and a technical drawing are completed; this means that the rim can be sent to a production phase.
The results of the project show also that the topology optimisation technology provided by Hyper-works and the advanced CAD system can be used to generate competitive designs with any design offices without any difficulties.
