Ralf Schelenz

Ralf Schelenz (* 1963 ) is a German mechanical engineer and professor at RWTH Aachen University .

Career

Schelenz studied mechanical engineering at the Rheinisch Westfälische Hochschule Aachen RWTH Aachen from 1984 to 1989 and chose to specialize in construction technology . He then worked for five years at the Institute for Machine Elements and Machine Design as a research assistant and did his doctorate in 1994 under Heinz Peeken.

Since 1995, Schelenz and his working group have been involved in research and industrial projects with the complex dynamic behavior of electro-mechanical drive systems, with a special focus on rail vehicles and wind turbines. He was one of the first to introduce multi-body simulation to investigate powertrain dynamics.

Since 2013 Schelenz has been managing director of the RWTH Aachen I³ Center for Wind Power Drives (CWD). He holds lectures on wind energy and machine acoustics with a special focus on the electro-mechanical drive train.

Ralf Schelenz is a member of the program committee of the "Conference for Wind Power Drives", which takes place every two years.
