Download or read book Design and Test of Dynamic Vibration Absorbers written by Steven F. Griffin and published by Springer Nature. This book was released on 2023-11-26 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to educate the beneficiaries of this technology, because there is so little awareness and understanding of what can be achieved with tuned mass dampers and vibration absorbers and of the relatively small increase in mass and complexity in exchange for the tremendous benefit in vibration reduction. It introduces the feedback approach to help understand why these devices work and are very helpful in modeling the devices on complicated structures. The hardware demonstrators are simple and directly scalable to more complicated structures. Once a reader successfully operates the demonstration hardware, the concepts in the book are directly scalable to implementations on very complex structures like airplanes and rockets. A recipe is provided to 3D print most of the parts as well as easy-to-find brackets and sensors. The whole kit can be assembled in an afternoon. The directions will be similar in detail to a DIY magazine article, providing simple, step-by-step procedures.

Download or read book Random Vibration in Mechanical Systems written by Stephen H. Crandall and published by Academic Press. This book was released on 2014-05-12 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Random Vibration in Mechanical Systems focuses on the fundamental facts and theories of random vibration in a form particularly applicable to mechanical engineers. The book first offers information on the characterization and transmission of random vibration. Discussions focus on the normal or Gaussian random process; excitation-response relations for stationary random processes; response of a single-degree-of-freedom system to stationary random excitation; wide-band and narrow-band random processes; and frequency decomposition of stationary random processes. The text then examines failure due to random vibration, including failure due to first excursion up to a certain level; fatigue failure due to a stationary narrow-band random stress process; failure due to an accumulation of damage; failure due to response remaining above a certain level for too great a fraction of the time; and failure mechanisms. The manuscript is a vital reference for mechanical engineers and researchers interested in random vibration in mechanical systems.

Available in PDF, EPUB and Kindle. Book excerpt: The tuned mass damper is one of the classic dynamic vibration absorbers with effective devices for energy dissipation and vibration reduction. The electromagnetically tuned mass damper system is extensively used for vibration reduction in engineering. A better understanding of the nonlinear dynamics of the electromagnetically tuned mass damper system is very important to optimize the parameters of such systems for vibration reduction. However, until now, one cannot fully understand complex periodic motions in such a nonlinear, electromagnetically tuned mass damper system. In this book, the semi-analytical solutions of periodic motions are presented through period-1, period-3, period-9, and period-12 motions. The corresponding stability and bifurcations of periodic motions are determined. The frequency-amplitude characteristics for bifurcation routes of such higher-order periodic motions are presented. This book helps people better understand the dynamical behaviors of an electromagnetically tuned mass damper system for the new development and design of vibration reduction and energy harvesting systems.

Download or read book Optimization of Tuned Mass Dampers written by Gebrail Bekdaş and published by Springer Nature. This book was released on 2022-04-07 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a timely book to summarize the latest developments in the optimization of tuned mass dampers covering all classical approaches and new trends including metaheuristic algorithms. Also, artificial intelligence and machine learning methods are included to predict optimum results by skipping long optimization processes. Another difference and advantage of the book are to provide chapters about several types of control types including passive tuned mass dampers, active tuned mass dampers, tuned liquid dampers, tuned liquid column dampers and inerter dampers. Tuned mass dampers (TMDs) are vibration absorber devices used in all types of mechanic systems. The key factor in the design is an effective tuning of TMDs for the desired performance. In practice, several high-rise structures and bridges were designed by including TMDs. Also, TMDs were installed after the construction of the structures after several negative experiences resulting from the disturbing sway of the structures. In optimum design, several closed-form expressions have been proposed for optimum frequency and damping ratio of TMDs, but the exact optimization requires iterative optimization approaches. The current trend is to use evolutionary algorithms and metaheuristic optimization methods to reach the goal.

Download or read book Frequency Tuning of Vibration Absorber Using Topology Optimization written by Swapnil Subhash Harel and published by . This book was released on 2017 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tuned mass absorber is a system for reducing the amplitude in one oscillator by coupling it to a second oscillator. If tuned correctly, the maximum amplitude of the first oscillator in response to a periodic driver will be lowered, and much of the vibration will be 'transferred' to the second oscillator. The tuned vibration absorber (TVA) has been utilized for vibration control purposes in many sectors of Civil/Automotive/Aerospace Engineering for many decades since its inception. Time and again we come across a situation in which a vibratory system is required to run near resonance. In the past, approaches have been made to design such auxiliary spring mass tuned absorbers for the safety of the structures. This research focuses on the development and optimization of continuously tuned mass absorbers as a substitute to the discretely tuned mass absorbers (spring- mass system). After conducting the study of structural behavior, the boundary condition and frequency to which the absorber is to be tuned are determined. The Modal analysis approach is used to determine mode shapes and frequencies. The absorber is designed and optimized using the topology optimization tool, which simultaneously designs, optimizes and tunes the absorber to the desired frequency. The tuned, optimized absorber, after post processing, is attached to the target structure. The number of the absorbers are increased to amplify bandwidth and thereby upgrade the safety of structure for a wide range of frequency. The frequency response analysis is carried out using various combinations of structure and number of absorber cell.

Download or read book Minimax Design of Parallel Multi mass Dynamic Vibration Absorbers written by Kerk Cheng Kee and published by . This book was released on 2011 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis discusses the design of multi-mass dynamic vibration absorbers in parallel configuration subject to uncertainties in the forcing frequency. A minimax parameter optimization approach is used to determine the optimum absorber mass parameters for different numbers of vibration absorbers without changing the total vibration absorber mass (constant mass ratio). Both main mass excitation and base excitation systems are examined. The effects of increasing the number of absorber masses are analyzed qualitatively through analysis of the system transfer function as well as quantitatively via numerical simulations. Increasing the number of absorber masses is shown to give improved robustness and overall vibration reduction in the main mass at the cost of increased motion of the absorber masses.

Download or read book Design and Optimization of Magnetorheological Elastomer Based Adaptive Tuned Vibration Absorber written by Fan Lin and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The excessive vibration if not properly controlled can cause premature fatigue failure of structural component. One effective way to attenuate vibration is to attach a tuned vibration absorber to the main structural component. Passive tuned vibration absorbers are mainly effective to attenuate vibration at specific tune frequencies and they significantly lose their effectiveness under mistuned conditions due to variation in environmental condition. The main objective of the present research study is to develop a wide-bandwidth and light-weight adaptive tuned vibration absorber (ATVA) featuring magnetorheological elastomer (MRE) to be tuned on a simply supported beam. The accelerance transfer function has been derived for both beam with and without ATVA. The effectiveness of the ATVA to control vibration at varying external excitation is then demonstrated. Proposed ATVA consists of C-Shape frame with winding coils, two MRE specimens and active mass. Isotropic MRE with 40% volume fraction has been experimentally tested and a quasi-static micromechanics and dynamic parametric model have been developed to predict the MRE's elastic modulus at various frequency and applied magnetic field. Using MRE models and magneto-circuit analysis, the frequency bandwidth of the ATVA was analytically obtained. Finally, a multidisciplinary design optimization formulation has then been developed to minimize the mass and maximize the frequency bandwidth of an ATVA featuring magnetorheological elastomer (MRE).
