Hermann Frahm (8 December 1867- 28 December 1939) was a german engineer and was the inventor of the lurch tanks to dampen ship rolling movements and the optical torsion indicator for measuring torques and torsional vibrations..[1][2]
Biography
Hermann Frahm was the son of Hans Frahm (1822–1886) and his wife Auguste Wiebke Margarethe, née Voß (1833–1877). His father worked as a master carpenter at Vorwerk in Büdelsdorf and as a master shipbuilder in Fockbek. His uncle Ernst Voß co-founded the Blohm & Voß shipyard.
Frahm attended secondary school in Rendsburg and then completed three years of training as a precision mechanic at Dennert and Pape in Altona, and as a mechanical engineer at Blohm & Voß. From 1887 to 1890 he studied mechanics and shipbuilding at the TH Hanover under Privy Councilor Prof. Dr. Eng. W.Rhien. He then worked for six months as an engineer and designer at Blohm & Voß and then as a designer at Haniel and Lueg in Düsseldorf.[1]
In 1892, Frahm took over the management of mechanical engineering in the port of Cologne from the city of Cologne. In 1898, he returned to Hamburg and worked again at Blohm & Voß. He headed the scientific testing department of the shipyard. Here, he was particularly involved in research into vibrations in machines and shaft lines. He invented several measuring devices, including a frequency meter and the vibration tachometer.
In 1904, Frahm was appointed technical director of Blohm & Voß.
He retired in 1936.
Scientific career
At the beginning of the 20th century, he invented the lurch tank, which became his most important invention. In doing so, he laid the foundation for numerous optimizations in shipbuilding.
Another important invention was the optical torsion indicator, which made it possible to determine torsional vibrations in shaft lines.
He get nominated for the Nobel prize in the 1913.[3]
Awards
- The technical universities of Hannover and Berlin named Frahm Dr. Ing. E. H. in 1922.
- The shipbuilding company awarded him the Golden coin in 1924.
- The Association of German Engineers, of which he was a member, distinguished him for his services to the development of vibration research with the Grashof commemorative coin in 1926.[1]
