Rostec specialists have manufactured key suspension parts of the first Russian automated electric racing car BRT-8D, which is being created by Bauman Moscow State Technical University. They are made by 3D printing at the Center for Additive Technologies of Rostec. The uniqueness of the parts lies in the special bionic design and the use of SLM technology, which gives the product high strength characteristics.

Racing teams, including the world leaders of Formula-1, consider the suspension as the most important tool affecting the aerodynamics and handling of the car.

The parts for the car were built at the Center for Additive Technologies on a 3D printer using selective laser fusion (SLM) technology by layer-upon–layer synthesis of metal powder in the printer construction chamber, thereby providing strength and rigidity, the most important characteristics for the suspension.

The shape was designed by the use of topological optimization, a method used to find the best layout of the material with specified technical parameters. The item has a special bionic design – the appearance of the product resembles elements of wildlife. This solution is used for the design of complex technical devices and structures. At the same time, the production of such bionic parts by the traditional method using casting and machining is impossible.

“The advantages of additive manufacturing are particularly noticeable in the project. The weight of the key suspension parts was significantly reduced, rigidity was increased. At the same time AM allow us to maintain all the strength characteristics, which are extremely important for a racing car. Today additive technologies make it possible to manufacture any product without design restrictions, significantly reducing the production time. Thus, the details for the BRT-8D were “printed” by the specialists of our Center in 64 hours” said Vladislav Kochkurov, ATC CEO.

The automated racing car is being developed by students of various faculties of Bauman Moscow State Technical University aimed at participating in the international student engineering competitions “FSD” (Formula Student Driverless). According to the terms of the competition, the car must be built in one year and comply with strict requirements for weight, dimensions and power of the electric motor. In 2022, the stages of the competition will be held in Italy, the Czech Republic and Russia. The Bauman Racing Team is preparing to perform for the first time on the BRT-8D car at the Russian stage of the championship. Previously, the team became the winner of Formula Student Russia three times, having started performing in various disciplines since 2012.
