You can see here the rear Bell Crank of a Formula SAE car. It's made of aluminium (7075-T6) and the design is topology optimized. It weights only 45 g.
Topology Optimization allows the designer to create superlightweight components that are also very strong.
The component is part of the Suspension System of the racecar F0711-7 made by the team Rennteam Uni Stuttgart:
This masterpiece of hi-tech engineering was made by 40 students of the University of Stuttgart in 2012. The car won 3 international competitions, reaching 1st place on the World Ranking.
Suspension uprights, brake pedal, differential carriers... many components of the car were topology optimized, making each of them as light and strong as possible. The result: 180 kg.
Topology Optimization is a very useful tool that allows engineers to create superlightweight designs - like this car. I'm sure you are going to hear a lot more about this cutting edge technology in the future!
