Modeling and Control of Magnetorheological Dampers for Seismic Response Reduction
Control of civil engineering structures for earthquake hazard mitigation represents a relatively new area of research that is growing rapidly. Control systems for these structures have unique requirements and constraints. For example, during a severe seismic event, the external power to a structure may be severed, rendering control schemes relying on large external power supplies ineffective. M...
متن کامل‘‘Smart’’ Base Isolation Strategies Employing Magnetorheological Dampers
One of the most successful means of protecting structures against severe seismic events is base isolation. However, optimal design of base isolation systems depends on the magnitude of the design level earthquake that is considered. The features of an isolation system designed for an El Centro-type earthquake typically will not be optimal for a Northridge-type earthquake and vice versa. To be e...
متن کاملDesign, Modeling and Control of Magnetorheological Fluid-Based Force Feedback Dampers for Telerobotic Systems
The overall goal of the research conducted in this paper is to develop next generation force feedback systems by combining novel Magnetorheological (MR) fluid based systems with microstructural analysis and advanced control system design. Two MR fluid based telerobotic systems are designed, prototyped and tested with medical applications. Force feedback control is employed to replicate in the m...

Title of Dissertation: DEVELOPMENT OF MAGNETORHEOLOGICAL FLUID ELASTOMERIC DAMPERS FOR HELICOPTER STABILITY AUGMENTATION Wei Hu, Doctor of Philosophy, 2005 Dissertation directed by: Professor Norman M. Wereley Department of Aerospace Engineering Conventional lag dampers use passive materials, such as elastomers, to dissipate energy and provide stiffness, but their damping and stiffness levels d...
متن کاملProposal of a new group of magnetorheological dampers
The article presents a construction and testing of a new family of magnetorheological dampers. The work began with testing currently used solutions, which exist inter alia in vibratory machines for example in washing machines. Basis on this job required damping parameters were obtained and then these parameters were used as input data in new devices designing process. A distinguishing feature o...
