Variable stiffness and damping MR isolator

This paper presents the development of a magnetorheological (MR) fluid-based variable stiffness and damping isolator for vibration suppressions. The MR fluid isolator used a sole MR control unit to achieve the variable stiffness and damping in stepless and relative large scope. A mathematical model of the isolator was derived, and a prototype of the MR fluid isolator was fabricated and its dyna...

Studies on Structural Vibration Control with MR Dampers Using Uga

This paper presents a new approach to reducing the seismic responses of spatial structures with magneto-rheological (MR) dampers using Genetic Algorithm with small populations (μGA). μGA is used to obtain the controller for the MR dampers for structural vibration reduction that is difficult to be solved by the classical optimal control. The advantages of μGA are of global property and having li...

Vibration mitigation of railway bridges using adaptive damping control

In this paper, the advantage of an adaptive damping system is presented. A damper with variable stiffness is tuned based on estimates of the real-time frequency response, facilitating optimal vibration mitigation. The performance of the developed routines is investigated on an existing tied arch railway bridge. Based on previous field measurements, resonant behaviour of several hangers was foun...

A Semi-Active Variable Stiffness and Damping System for Vibration Control of Civil Engineering Structures

This paper proposes a new semi-active variable stiffness and damping system (AVSD) for vibration control of civil engineering structures. The AVSD system can alter rigidity and damping of the controlled structure at each control interval to attenuate the structural responses. The composition of two hydraulic cylinder-piston systems of the AVSD system is capable of amplifying the interstory drif...
