Computational Techniques of Rotor Dynamics with the Finite Element Method

Rotor dynamics is both a classical and a modern branch of engineering science.However, analyzing the rotational behavior of flexible bodies, especially those with irregular shapes like propellers and blades, requires more modern tools such as finite elements, which is what this book focuses on.

Arne Vollan studied aeronautical engineering at the Technical University of Trondheim (Norway) and Aachen (Germany) and holds the Diplom Ingenieur degree. He was employed by several aeronautical companies such as VFW Fokker (now Airbus), Helicopter Technik Muenchen, Dornier, Nationaal Lucht en Ruimtevaartlaboratorium, and Pilatus Aircraft as a dynamic and aeroelastic specialist. He was also a consultant and developed programs for the analysis of rotating structures like wind turbines and propellers. Since 2002, he has been working at AeroFEM GmbH in Switzerland on rotor dynamics and the aeroelasticity of aircraft and large wind turbines. He is still active in consulting, and the new industrial application case study presented in the last chapter is a result of that activity.

Louis Komzsik is a graduate of the Technical University of Budapest with an engineering degree and the Eotvos University of Sciences in Budapest with a mathematics degree, and he holds a Doctorate from the Technical University of Budapest, Hungary. He was employed by the Hungarian Shipyards from 1972 to 1980 and worked at the McDonnell Douglas Corporation in 1981 and 1982. He was the chief numerical analyst leading the development of NASTRAN atthe MacNeal Schwendler Corporation from 1983 to 2003 and served in a similar capacity at Siemens PLM Software in California from 2003 to 2016. Since his retirement from industry in 2017, he has been lecturing at The University of California in Irvine and at Obuda University in Budapest, Hungary, where he is presently Professor Emeritus of Applied Mathematics.
