Available in PDF, EPUB and Kindle. Book excerpt: Based on a systematic understanding of its theoretical foundations, “Self-Excited Vibration: Theory, Paradigms, and Research Methods” offers a method for analyzing any type of self-excited vibration (SEV). After summarizing the research results of various SEV phenomenon, including chatter, shimmy, rotor whirl, flutter, gallop, and SEV of man-made control systems, the author constructs a general constitutive mechanism of SEV, as well as a common research program and detailed analysis technique. All of these will help the reader independently analyze any new SEV phenomena.

Available in PDF, EPUB and Kindle. Book excerpt: An in-depth introduction to the foundations of vibrations for students of mechanical engineering For students pursuing their education in Mechanical Engineering, An Introduction to Mechanical Vibrations is a definitive resource. The text extensively covers foundational knowledge in the field and uses it to lead up to and include: finite elements, the inerter, Discrete Fourier Transforms, flow-induced vibrations, and self-excited oscillations in rail vehicles. The text aims to accomplish two things in a single, introductory, semester-length, course in vibrations. The primary goal is to present the basics of vibrations in a manner that promotes understanding and interest while building a foundation of knowledge in the field. The secondary goal is to give students a good understanding of two topics that are ubiquitous in today's engineering workplace - finite element analysis (FEA) and Discrete Fourier Transforms (the DFT- most often seen in the form of the Fast Fourier Transform or FFT). FEA and FFT software tools are readily available to both students and practicing engineers and they need to be used with understanding and a degree of caution. While these two subjects fit nicely into vibrations, this book presents them in a way that emphasizes understanding of the underlying principles so that students are aware of both the power and the limitations of the methods. In addition to covering all the topics that make up an introductory knowledge of vibrations, the book includes: ● End of chapter exercises to help students review key topics and definitions ● Access to sample data files, software, and animations via a dedicated website

Download or read book Robust Structural Design against Self Excited Vibrations written by Gottfried Spelsberg-Korspeter and published by Springer Science & Business Media. This book was released on 2013-03-23 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book studies methods for a robust design of rotors against self-excited vibrations. The occurrence of self-excited vibrations in engineering applications if often unwanted and in many cases difficult to model. Thinking of complex systems such as machines with many components and mechanical contacts, it is important to have guidelines for design so that the functionality is robust against small imperfections. This book discusses the question on how to design a structure such that unwanted self-excited vibrations do not occur. It shows theoretically and practically that the old design rule to avoid multiple eigenvalues points toward the right direction and have optimized structures accordingly. This extends results for the well-known flutter problem in which equations of motion with constant coefficients occur to the case of a linear conservative system with arbitrary time periodic perturbations.
Download or read book Preliminary Investigation of Self excited Vibrations of Single Planing Surfaces written by Elmo J. Mottard and published by . This book was released on 1956 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A preliminary investigation was made of self-excited vibrations of single planing surfaces. A self-excited oscillation requiring freedom in rise but not in trim occurred with high aspect ratio (order of 10) of the wetted portion. This vibration could be controlled most successfully by methods (such as the use of dead rise) which limited the wetted aspect ratio.

Available in PDF, EPUB and Kindle. Book excerpt: The increasing automation of driving functions and the electrification of powertrains present new challenges for the chassis with regard to complexity, redundancy, data security,and installation space. At the same time, the mobility of the future will also require entirely new vehicle concepts, particularly in urban areas. The intelligent chassis must be connected, electrified, and automated in order to be best prepared for this future.
Download or read book Active Vibration Control of a Self excited Vibrating System Utilizing Periodic External Excitation written by Scott Donald Monroe and published by . This book was released on 2016 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: A common phenomenon observed in dynamic mechanical systems is the presence of selfexcited vibrations under normal operating conditions. A classic example of this phenomenon can be seen on electrical power transmission lines that is commonly referred to as transmission line gallop. Transmission lines have been known to "gallop", oscillate up and down, with the oscillation increasing in magnitude until mechanical failure of the system occurs. The type of vibration that is occurring is classified as a self-excited vibration and is an example of a system that is dynamically unstable. In his classic text book, Mechanical Vibrations, J.P. Den Hartog presented this phenomena and described the dynamics of the phenomena in great detail. In addition, he proposed an apparatus that clearly and simply illustrates this phenomena to the reader. This apparatus is a simple mass-spring system that can be constructed and used to demonstrate the self-excited vibrations with the use of a small desk fan. This thesis will cover the theory and derivation of a proposed control method to settle the self-excited vibrating system. The approach for quenching the vibrations will utilize the theory of applying a controlled periodic force that mimics the forces created by a tuned mass damper. In addition to developing a control method, the thesis will also look at the development of the apparatus proposed by Den Hartog as well as implement the proposed control method and evaluate its effectiveness in canceling the self-excited vibration. And finally, in the development of this apparatus and control system, efforts will be made to utilize simple low cost micro-controller (Arduino) and hobbyist hardware (servos and springs) with the intention that this system could be easily constructed by students and educators in the future. The goal of this thesis was to develop a control method and test the theory for effectiveness after constructing the aforementioned apparatus. The results of this research activity have the potential to be extended and adapted for many applications where self-excited vibrations may occur. In addition, the platform that was developed to to test the theories in this thesis could be extended to further research and demonstration purposes.
