This book was released on 2005 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) However, the electromagnetic damper provides flexibility not available previously to building designers as it can be used as a semi-active damper, as an actuator or as an energy regenerator without physical modifications to the device. Finally, we developed a design methodology for the electromagnetic damper to achieve a specified damping performance and introduced two techniques for the dynamic response analysis of buildings with electromagnetic dampers: One based on frequency domain approximations and one based on state-space models.
Download or read book Feasibility of Passive Electromagnetic Dampers as Energy Harvesters in Large Structures written by Christopher M. Hendrix and published by . This book was released on 2013 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a trend in structural design toward energy efficient design and motion based design. The strategy of motion based design is controlling the movement of structures to meet certain dynamic response requirements by damping the structure. Structural damping dissipates the energy of external loads internally within the structure. A simple idea is to connect the two design strategies to control the motion of a structure while harvesting this dissipated energy by transducing it to electrical energy via passive electromagnetic damping. This study will attempt to determine the feasibility of using passive electromagnetic damping to control the motion and harvest the energy of damping of large scale structures.

Download or read book Motion and Vibration Control written by Heinz Ulbrich and published by Springer Science & Business Media. This book was released on 2008-12-23 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motion and vibration control is a fundamental technology for the development of advanced mechanical systems such as mechatronics, vehicle systems, robots, spacecraft, and rotating machinery. Often the implementation of high performance, low power consumption designs is only possible with the use of this technology. It is also vital to the mitigation of natural hazards for large structures such as high-rise buildings and tall bridges, and to the application of flexible structures such as space stations and satellites. Recent innovations in relevant hardware, sensors, actuators, and software have facilitated new research in this area. This book deals with the interdisciplinary aspects of emerging technologies of motion and vibration control for mechanical, civil and aerospace systems. It covers a broad range of applications (e.g. vehicle dynamics, actuators, rotor dynamics, biologically inspired mechanics, humanoid robot dynamics and control, etc.) and also provides advances in the field of fundamental research e.g. control of fluid/structure integration, nonlinear control theory, etc. Each of the contributors is a recognised specialist in his field, and this gives the book relevance and authority in a wide range of areas.
Download or read book A Study on Energy Harvesting Through the Use of Electromagnetic Dampers in Motion Control Schemes written by Geoffrey Francis Bomarito and published by . This book was released on 2010 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there is a trend in most fields toward more environmentally friendly products and processes. This trend toward sustainable living is often dubbed the "Green Revolution". Because the Green Revolution is concerned with environmentally friendly ways of energy production, and structural engineering often has the task of controlling and dissipating energy, the logical step would be to unite the two concepts. This study investigates the use of the electromagnetic damper as an energy harvesting device in multiple damping schemes. It is shown that the use of the electromagnetic damper in a tuned mass damper scheme produces the most available energy to be harvested.

Download or read book Regenerative Electromagnetic Dampers in High rise Buildings written by Matthew Schwabauer and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High-rise buildings constantly sway due to the influence of wind. This movement is especially noticeable for tall and slender buildings because they inherently have smaller stiffness than shorter, less slender buildings and therefore have larger drifts. This issue can be mitigated with the use of a tuned mass damper (TMD) which reduces the wind-induced dynamic response of high-rise buildings. Conventional TMDs have viscous dampers to help dissipate energy of the building motion through heat transfer to the environment. This report proposes a new type of damper that can be used instead of viscous dampers that would convert the dissipated building energy into electricity. The proposed type of damper is called an electromagnetic (EM) damper and uses induced Eddy currents to create the damping effect needed to mitigate building movement. The report reviewed experimental and numerical studies that have been conducted on this novel energy regeneration system. These studies found that in a specific case 27.4% of the total energy stored in building oscillation can be converted to electricity. This report followed a case study, Taipei 101, and calculated that the building stores 108 kW of power during a light breeze. Applying the efficiency found in the aforementioned studies to Taipei 101 provides 30 kW of electricity that could be produced from this regenerative TMD system during light wind conditions. Regenerative TMDs with EM dampers have the potential to produce a significant amount of electricity while maintaining effective movement control for high-rise buildings, but the current cost of these devices is too high to be economically feasible with current technology.
