Short description:

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.

Long description:

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 structures


• Details of highly efficient and accurate computational and numerical techniques for dynamic simulations


• Interpretation of computational results, which is instrumental to developing stable rotating machinery


• Practical application examples of rotational structures? dynamic response to external and internal excitations


• An FEM case study that illustrates the computational complexities associated with modeling and computation of forces of rotor dynamics


• Assessment of propellers and turbines that are critical to the transportation and energy industries

Useful to practicing engineers and graduate-level students alike, this self-contained volume also serves as an invaluable reference for researchers and instructors in this field.

CRC Press Authors Speak

Louis Komzsik introduces you to two books that share a common mathematical foundation, the finite element analysis technique. Watch the video.

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 ?
