One of the competing teams in the Formula SAE competition is FST Lisboa of the University of Lisboa, Portugal. 39 students from seven different faculties use their know-how on motorsport technology and high-precision engineering to design and build a racing car fit for the competition. For their last car, the team had to design a new set of rims to further reduce the weight of the rim set by 25 percent. With linear static analyses and topology optimization solutions from Altair, the team was able to make sound geometry choices for the rims, and reduce the weight of the components, while meeting all compliance requirements.
