Numerical Simulation and Torsional Vibration Mitigation of Spatial Eccentric Structures with Multiple Magnetorheological Dampers

Controllable Shock and Vibration Dampers Based on Magnetorheological Fluids

Innovative magnetorheological dampers (MR dampers) for shock and vibration damping, based on magnetorheological fluids (MRFs), are described. Important fields of their application are loading processes, impact dampers in security systems as well as vibration dampers for machines and cars. Various models for describing the MR dampers are discussed. The characteristic feature of the MR dampers is...

Torsional Vibration of Eccentric Building Systems

Modelling and Simulation of Electro- and Magnetorheological Fluid Dampers

Electroand magnetorheological fluids are smart, synthetic fluids changing their viscosity from liquid to semisolid state within milliseconds if a sufficiently strong electric or magnetic field is applied. When used in suitable devices, they offer the innovative potential of very fast, adaptively controllable interfaces between mechanical devices and electronic control units. This paper gives an...

Adaptive Sliding Mode Control for Civil Structures Using Magnetorheological Dampers

An adaptive sliding mode controller for vibration control is proposed in this paper for structures embedded with magnetorheological (MR) dampers. Civil structures and buildings are liable to damages during earthquake periods. The application of structural control methodologies is important in order to suppress vibrations due to seismic phenomena and dynamic loading. The use of sliding mode cont...

Optimal Control via Integrating the Dynamics of Magnetorheological Dampers and Structures

Magnetorheological (MR) dampers have the advantage of being tuned by low voltages. This has attracted many researchers to develop semi-active control of structures in theory and practice. Most of the control strategies first obtain the desired forces of dampers without taking their dynamics into consideration and then determine the input voltages according to those forces. As a result, these st...
