Hans Dresig
Hans Dresig (31 January 1937 in Dölau near Halle (Saale), Germany – 25 April 2018 in Lichtenau, Saxony) was a German Professor for Applied mechanics and Theory of Mechanisms and Machines. Career. Hans Dresig started to study in 1954 at the Dresden University of Technology. As student he specialized in transportation machines and equipment. His special interests were theoretical subjects, like Applied Mathematics, Physics, Technical Mechanics and Theory of Mechanisms and Machines. After graduating in 1960 he joined the chair of Technical Mechanics. Since then he has been working on dynamics of machines, for instance with mechanisms, oscillating conveyors  and cranes. He received his master's degree and Doctor Degree from Dresden University of Technology in 1965. After defending his doctoral thesis he started working for a design office in the crane construction company “Kranbau Eberswalde” in Eberswalde. After 4 years he was appointed to a lecturer at the Chemnitz University of Technology. He also completed his post-doctor work there in 1970. After having worked as a lecturer for 8 years he was offered a professorship in 1978. Hans Dresig was a Professor and Ph. D. Supervisor in Chemnitz University of Technology. During that time he has been  giving lectures on a variety of subjects, such as Statics, Strength of materials, Dynamics, Theory of Vibrations, Balancing of rotating masses and Optimization of Machines. In addition to these lectures he worked on many projects with industrial partners in mechanical engineering. He wrote together with Franz Holzweißig the textbook “Dynamics of Machinery”. In 1979 was published the first edition. In 2010 the 10th edition came out in Germany and today it is available in Vietnamese, English and Chinese translation. His researches have been published in more than 220 papers. In addition, he is author and co-author of about 10  books and also the inventors of about 20 patents. He is a member in Committee of Drive Technology in the Association of German Engineers (VDI), an advisor of “Alexander von Humboldt Foundation” and German Research Foundation (DFG). He has held lectures in USA, Switzerland, Austria, France, Italy, Poland, Czechoslovakia, Bulgaria, Russia, Ukraine, Vietnam and China. Since 2009 he is a Visiting professor at Nanjing Agricultural University, China.
