About

R. Stefanelli is a mechanical engineering researcher whose work centers on the dynamics and mechanics of automated transmission systems, with a particular focus on robotized gearbox actuators. Stefanelli's research has made meaningful contributions to the simulation and analysis of cam-actuated mechanisms, a critical component in the development of automated manual transmissions that bridge the gap between traditional manual and fully automatic gearboxes. Among Stefanelli's most notable contributions are detailed investigations into the dynamic behavior of barrel cam actuators used in robotized gearboxes. By employing finite element approximations of beam-on-elastic-foundation theory alongside penalty-based contact modeling, Stefanelli developed virtual models capable of accurately simulating the complex contact dynamics between cam and follower components. This work progressed from dynamic simulation in 2004 to a more comprehensive examination of efficiency and wear mechanisms by 2008, reflecting a deepening understanding of tribological and mechanical performance under real operating conditions. Though Stefanelli's citation count remains modest, with key papers each garnering 3 citations, the specialized and technically demanding nature of this research provides valuable tools for engineers designing more efficient and durable transmission actuators. This work contributes to broader efforts in automotive engineering aimed at improving vehicle fuel efficiency and drivetrain reliability.
