Inhaltsverzeichnis

Leben

Nach der Matura an der HTL Steyr studierte Wohlhart ab 1947 an der Technischen Hochschule (heute Technische Universität) in Graz Maschinenbau. Nach Jahren als Hochschulassistent promovierte er 1966 zum Doktor der Technischen Wissenschaften. 1969 trat er bei der DFVLR, der Deutschen Forschungsanstalt für Luft- und Raumfahrt in Mülheim an der Ruhr ein. 1971 erhielt er an der Ruhruniversität Bochum die Venia Legendi für Mechanik. Er hielt Vorlesungen in Bochum, Aachen, Leoben und Innsbruck und Anfang 1972 konnte er als ordentlicher Hochschulprofessor für Theoretische Maschinenlehre in Graz beginnen. 1977 erfolgte die Ernennung zum ordentlichen Professor und Vorstand des Institutes für Mechanik. Wohlhart hat in den 20 Jahren an der TU rund 45 wissenschaftliche Arbeiten verfasst. Er war zwölf Jahre lang war Vorsitzender des Österreichischen Nationalkomitees der IFToMM, der International Federation for the Theory of Machines and Mechanisms, die ihn 1995 zum Member des Executive Councils gewählt hat.
