Machine Elements

Academic Career and Research Areas

Prof. Stahl (*1969) conducts research in the area of mechanical drive systems. His main research interests are drive components, such as gears, synchronizers, multi-disc clutches, rolling bearings, and electromechanical drive systems. The focus of his investigations is on load capacity, efficiency, dynamics and EHD tribocontact. Research results are incorporated into the development of calculation programs and standardization processes.
Prof. Stahl studied mechanical engineering at TUM and did his doctorate from 1994 to 2000 at the Institute of Machine Elements. In 2001, he joined BMW, first as a gear development engineer, then as head of gear development in Dingolfing. From 2006 on, he worked at MINI Oxford as quality manager for transmissions, later as quality manager for powertrains and suspensions. In 2009, he took over responsibility for the early development and innovation management of powertrain and vehicle dynamics systems at BMW in Munich. Since 2011, Stahl has been a full professor at the Institute of Machine Elements, the Gear Research Centre (FZG)
