This book was released on 2018-12-17 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses efforts to control the low-frequency vibration transmission of typical power equipment and pipeline systems of ships, exploring the use of active and passive hybrid vibration isolation and adjustable dynamic vibration absorption technologies. It also proposes an adaptive feed-forward control strategy and studies a distributed feed-forward control hardware system. In addition, the book presents a three-way dynamic vibration absorption theory used to design a pipeline-system adjustable dynamic vibration absorber, which offers a number of advantages, such as compact structure, easy assembly and disassembly, low power consumption, excellent vibration control effect and wide frequency band adjustable ability, etc. This book is a valuable resource for researchers and engineers in the fields of noise and vibration control, active control systems, active vibration isolation and adaptive dynamic vibration absorption.

This book was released on 2013-06-05 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: With progress in technology, the problem of protecting human-beings, ma chines and technological processes from !>Ources of vibration and impact has become of utmost importance. Traditional "classical" methods of pro tection, based upon utilising elastic passive and dissipative elements, turn out to be inefficient in many situations and can not completely satisfy the complex and often contradictory claims imposed on modern vibration protection systems which must provide high performance at minimum di mensions. For these reasons, active vibration protection systems, which are actually systems of automatic control with independent power sources, are widely used nowadays. Appearing and developing active systems require that traditional ap proaches to the analysis and synthesis of vibration protection systems must be revised. Firstly, there exists the necessity to re-state the problem of vi bration protection from mechanical actions as an equivalent problem in closed-loop control systems design, which is to be solved by the methods of control theory. Furthermore, it turns out that certain inherent proper ties of active systems must be taken into account for a proper design. In the majority of cases, the dynamic models of the objects to be protected and the bases to which these objects are to be attached must be revised. They are no longer considered as rigid bodies but elastic bodies with weak dissipation.

Download or read book A Low Cost DC coupled Active Vibration Isolation System written by Kevin Kar-Leung Miu and published by . This book was released on 2008 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, I designed and implemented an isolation system that interfaces with traditional air mounts for improved force disturbance rejection relative to passive optical tables.Force disturbance rejection and position alignment are two major functional requirements of vibration isolation systems. With conventional passive isolation systems, a tradeoff exists between improving force disturbance rejection maintaining ground vibration isolation. Commercial active isolators address such a tradeoff through the use of inertial sensors, but the AC-coupled nature of the sensors leads to an inconvenient low frequency response. By referencing a payload stiffly to a softly suspended proof mass, both of the aforementioned functional requirements can be resolved while maintaining ground disturbance isolation performance. Philips Applied Technologies originally developed the concept, named Advanced Isolation ModuleS (AIMS).The AIMS system uses a relative displacement measurement between a payload which is to be isolated from vibrations and a proof mass as feedback. The displacement sensor allows the inertial measurement to be DC-coupled. The objective of this research is to find a relatively low-cost approach for the AIMS concept.A 1-DOF active vibration isolation system based on closed loop control utilizing the DC-coupled inertial measurement as feedback was retrofitted onto an optical table. The coil of a commercial geophone was used as the proof mass, as the geophone provides a relatively inexpensive, low frequency suspension. Error budgeting was performed on the system to estimate and improve payload acceleration noise levels. The results yielded a system bandwidth of 30 Hz and a total system acceleration la value of approximately 1 mm/s2.

Book excerpt: Currently, many smart materials exhibit one or multifunctional capabilities that are being effectively exploited in various engineering applications, but these are only a hint of what is possible. Newer classes of smart materials are beginning to display the capacity for self-repair, self-diagnosis, self-multiplication, and self-degradation. Ultimately, what will make them practical and commercially viable are control devices that provide sufficient speed and sensitivity. While there are other candidates, piezoelectric actuators and sensors are proving to be the best choice. Piezoelectric Actuators: Control Applications of Smart Materials details the authors’ cutting-edge research and development in this burgeoning area. It presents their insights into optimal control strategies, reflecting their latest collection of refereed international papers written for a number of prestigious journals. Piezoelectric materials are incorporated in devices used to control vibration in flexible structures. Applications include beams, plates, and shells; sensors and actuators for cabin noise control; and position controllers for structural systems such as the flexible manipulator, engine mount, ski, snowboard, robot gripper, ultrasonic motors, and various type of sensors including accelerometer, strain gage, and sound pressure gages. The contents and design of this book make it useful as a professional reference for scientists and practical engineers who would like to create new machines or devices featuring smart material actuators and sensors integrated with piezoelectric materials. With that goal in mind, this book: Describes the piezoelectric effect from a microscopic point of view Addresses vibration control for flexible structures and other methods that use active mount Covers control of flexible robotic manipulators Discusses application to fine-motion and hydraulic control systems Explores piezoelectric shunt technology This book is exceptionally valuable as a reference for professional engineers working at the forefront of numerous industries. With its balanced presentation of theory and application, it will also be of special interest to graduate students studying control methodology.
