Dual Clutch Transmissions have conquered an important fraction of the market, mainly in Europe, as a result of their improvements concerning efficiency.

Once the power flow from engine to the transmission is not interrupted, fuel efficiency increases radically. Furthermore, extreme fast and soft shifts provide the most dynamic and smooth acceleration of any vehicle on the market, being particularly suitable on high performance vehicles. The drivers have also experienced singular comfort, since they can choose whether to control the shifting or let the computer do it automatically.

Nevertheless, to overcome the elevated requirements imposed to the system components, in special the release bearings, the industry has dispended considerable efforts on the development of new processes and design methodologies.

This paper focuses on design-oriented simulation of DCT release bearings on a fully virtual environment, with the aim of defining new approaches and calculation procedures within the early steps of product definition.
