Franz Kienast

from Wikipedia, the free encyclopedia

Franz Wilhelm Bernhardt Kienast (born November 26, 1895 in Berlin ; † May 26, 1965 in Dresden ) was a German mechanical engineer and most recently professor of conveyor technology at the Faculty of Mechanical Engineering at the TU Dresden .

Life

After graduating from high school in 1914, Kienast did military service and after the end of the First World War studied mechanical engineering at the TH Dresden, which he graduated with a diploma in 1921.

He began his professional career in 1921 as an assistant in the head office of Werschen-Weißenfelser Braunkohlen AG ( Halle ), took on the position of mechanical engineer at the mining inspection in 1922, became department director in 1926 and was plant director from 1933 to 1938.

As an external person , Kienast received his doctoral thesis on the extraction and movement of material to be conveyed on overburden excavators in open-cast lignite mining in 1935 from the TH Dresden to Dr.-Ing. PhD. From 1938 initially self-employed, from 1940 to 1941 he took on the position of machine director at Sudetenländische Bergbau AG Brüx within the conglomerate of the Reichswerke Hermann Göring .

After the war, he was from 1945 to 1946, first lecturer for Machine Engineering and Electrical Engineering and Director of the Machine Institute of Mining Academy (November 1, 1966 in Clausthal University of Technology renamed) before it a year later sworn expert of the Chamber of Commerce Braunschweig and Managing Director of Dr.-Ing. Kienast GmbH Braunschweig advanced.

In 1951 the TH Dresden appointed him full professor for conveyor technology, where he successfully taught and researched until his retirement in 1962 and was director of the Institute for Conveyor Technology (later the Institute for Conveyor Technology and Construction Machinery). His graduate students included u. a. Karl Höffl .

Kienast was heavily involved in the development of “socialist community work”. He headed such a working group, consisting of workers and engineers from the VEB Ferroalloyment Works Mückenberg and VEB Lippendorf , in order to solve the problem of mechanical loading of ferro-silicon furnaces. For this, Kienast was awarded the Patriotic Order of Merit in silver in 1957. His institute worked with the Departments of Materials Handling in Moscow and Prague together, from the 1957 conference series mechanization in earthworks arose later in the six countries of the CMEA involved.

The entire field of conveyor technology played a central role in open-cast lignite mining in the GDR . On the civil engineering side, Kurt Beyer had successfully dealt with the structural analysis and structural design of the steel construction of opencast mining equipment at the TH Dresden and in his Dresden engineering office since 1928 . The civil engineering professor Ludwig Mann also moved in this area. Kienast further developed conveyor technology from the perspective of mechanical engineering and has published numerous publications in Verlag Technik since the mid-1950s : ropes and chains, engine parts, brakes and ratchets, load handling devices, pulley blocks, pulling devices, winches, bridge cranes, portal cranes, continuous conveyors, open-cast mining equipment, elevators and storage technology .

Kienast played a decisive role in the scientific and technical advances made in conveyor technology as a branch of mechanical engineering in the GDR.
