Zusatztext Aeronautical engineers Vollan and Komzsik have worked in many companies designing rotors that blow wind or that wind turns and have cooperated on several projects over the past quarter century. From that collaboration! they explain how to apply modern analysis tools such as finite elements to the rotational behavior of flexible bodies ? -SciTech News! Vol. 66! September 2012 Informationen zum Autor Arne Vollan studied aeronautical engineering at the Technical University of Trondheim (Norway) and Aachen (Germany), and holds the degree Diplom Ingenieur. 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. Louis Komzsik is a graduate of the Technical University of Budapest with an engineering degree and the Eötvös 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 at the MacNeal-Schwendler (now MSC Software) Corporation for two decades. Since 2003 he has been the chief numerical analyst at Siemens PLM Software. For the past 30 years he has been the architect of the modern numerical methods of NASTRAN, the world’s leading finite element analysis tool in structural engineering. Klappentext Applications of rotor dynamics are associated with important energy industry machinery, such as generators and wind turbines, as well as airplane engines and propellers. This book presents techniques that employ the finite element method for modeling and computation of forces associated with the rotational phenomenon. It examines practical computational techniques for simulating behavior of rotational structures and then using the results to improve fidelity and performance. The authors also discuss state-of-the-art engineering software used for computational simulation, including eigenvalue analysis techniques used to ensure numerical accuracy of the simulations. Zusammenfassung For more than a century! we have had a firm grasp on rotor dynamics involving rigid bodies with regular shapes! such as cylinders and shafts. However! to achieve an equally solid understanding of the rotational behavior of flexible bodies-especially those with irregular shapes! such as propeller and turbine blades-we require more modern tools and methods.Computational Techniques of Rotor Dynamics with the Finite Element Method explores the application of practical finite element method (FEM)-based computational techniques and state-of-the-art engineering software. These are used to simulate behavior of rotational structures that enable the function of various types of machinery-from generators and wind turbines to airplane engines and propellers. The book's first section focuses on the theoretical foundation of rotor dynamics! and the second concentrates on the engineering analysis of rotating structures. The authors explain techniques used in the modeling and computation of the forces involved in the rotational phenomenon. They then demonstrate how to interpret and apply the results to improve fidelity and performance. Coverage includes:Use of FEM to achieve the most accurate computational simulation of all gyroscopic forces occurring in rotational structuresDetails of highly efficient and accurate computational and numerical techniques for dynamic simulations Interpretation of...
