Prof. Dr.-Ing Jörn Holland

On July 1, 1972, Prof. Dr.-Ing. Jörn Holland was appointed full professor and full professor in the field of "Friction Technology and Machine Kinetics" at Clausthal University of Technology.
Dr. Holland was born on April 5, 1932 and, after graduating from the humanistic Wilhelm-Gymnasium in Braunschweig in 1950, studied "General Mechanical Engineering" at the TH Braunschweig and the TH Hannover, where he passed his main diploma examination "with distinction" in 1955. After completing his studies, he worked for several years as a research assistant at the Institute for Piston Engines at the TH Hannover and completed his doctorate under Prof. Dr. Klüsener with the topic "Contribution to the determination of lubrication conditions in combustion engines". The method he developed for the design of plain bearings under transient load and for determining the crankpin travel in the bearing clearance circle is now widely used in practice for the design of plain bearings in piston engines.
In 1958, he joined Eisenwerk Wülfel, Hanover-Wülfel, where he became head of the development department. After working as an assistant manager for a time, he was put in charge of all design departments at the parent company. During his time at Eisenwerk Wülfel, Dr. Holland was primarily concerned with issues of plain bearing construction, continuously variable rolling gears, gear drives and flexible couplings. Various publications have appeared in the specialist literature on these topics.
From 1970, he was employed as Managing Director of the company "Heylo Forschungs- und Entwicklungs-GmbH". As part of his work at this company, his main areas of interest were environmental protection and thermal afterburning.
Prof. Holland took over the Chair of Friction Technology and Machine Kinetics on July 1, 1972, succeeding Prof. Vogelpohl, whose Department of Friction Research at the Max Planck Institute for Flow Research was incorporated as the Chair of Friction Technology and Machine Kinetics at Clausthal University of Technology. The task of the new chair will be to carry out research and teaching in the field of friction technology and tribology.
