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...
متن کاملINVESTIGATION OF THE OPTIMAL SEMI-ACTIVE CONTROL STRATEGIES OF ADJACENT BUILDINGS CONNECTED WITH MAGNETORHEOLOGICAL DAMPERS
This study investigates the efficacy of optimal semi-active dampers for achieving the best results in seismic response mitigation of adjacent buildings connected to each other by magnetorheological (MR) dampers under earthquakes. One of the challenges in the application of this study is to develop an effective optimal control strategy that can fully utilize the capabilities of the MR dampers. H...
متن کاملAdaptive 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...
متن کاملOptimal 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...
متن کاملEarthquake Response of Adjacent Structures with Viscoelastic and Friction Dampers
We study the seismic response of two adjacent structures connected with a dry friction damper. Each of them consists of a viscoelastic rod and a rigid block, which can slide without friction along the moving base. A simplified earthquake model is used for modeling the horizontal ground motion. Energy dissipation is taken by the presence of the friction damper, which is modeled by the set-valued...
