Wilhelm Müller (engineer)

from Wikipedia, the free encyclopedia

Wilhelm (Johannes) Müller (born December 10, 1882 in Miesenheim ; † February 17, 1956 in Aachen ) was a German railway engineer and rector of RWTH Aachen University .

Live and act

After graduating from high school in 1903, the son of a farmer studied civil engineering at the Technical Universities of Karlsruhe and Danzig and graduated in 1909 with an engineering degree . He then gained practical experience in the construction and operation of railways as a government builder in the cities of Katowice , Halle (Saale) and Mainz between 1910 and 1921 . In addition, he enrolled at the Technical University of Darmstadt , where he obtained his doctorate in 1918 with his thesis on " New drawing methods for the exact determination of the mass of the earth in railway and road constructions as a result of an error investigation in the usual way of calculation ". and completed his habilitation in the same position just two years later. From 1921 to 1924, Müller then worked as a government building officer in the building department of the Prussian Ministry of Public Works, which later became the Reich Ministry of Transport . In the same period in 1922 was followed at the Technical University of Berlin his Habilitation , and he was then additionally there as a lecturer taken.

On April 1, 1924 Müller was followed by a call to the Technical University of Dresden , where he remained as professor until 1933 before then back went to the Technical University of Berlin, where in the difficult times during the he Third Reich and the Second World War in worked in the same function. Finally, in 1946, he moved to RWTH Aachen University, where he took over the professorship for railways in the years that the TH was established after the war. Müller stayed here until his retirement in 1953, from 1947 onwards he held the post of dean of the Faculty of Civil Engineering and also headed the university from 1948 to 1950 as its rector.

During his research years, Müller specialized primarily in recognizing the relationships between space and time in rail transport using the physical and mathematical means available at the time and examining them with new graphical representations. With a so-called “time angle”, he succeeded in depicting the relationship between the stationary systems of the roadway and the vehicles on it, depending on the performance curves of the respective drive machines and the mass of earth to be transported. These findings were among the considerations on the operational and economic designs of the technical traffic facilities such as in yards and shunting and, consequently, one in shaping the hump in flat stations or Abrollanlagen in slope stations. With these analyzes, he was able to significantly increase the cost-effectiveness of the systems in both travel and freight transport .

Another focus of his research and teaching activities was the development of a systematic driving dynamics of the means of transport, which he wrote down in his two-volume main work: " Driving dynamics " , which was awarded by the Association of Central European Railway Administrations (VMEV) . In this, he summarized the two main areas of technical railroading, the fixed systems and the movement of the rail vehicles into an overall system. Numerous publications round off the image of an extremely committed and competent scientist.

In addition, during his last years of service, Müller, along with professors Franz Krauss and Peter Mennicken, was one of the co-founders of the " Society for the Award of the International Charlemagne Prize of the City of Aachen " on the part of the university in 1949 and one of the co-signers of the proclamation that was written on this from Christmas 1949 and thus also a member of the first Charlemagne Prize Board.
