An Experimental Study of MR Dampers for Seismic Protection
In this paper, the efficacy of magnetorheological (MR) dampers for seismic response reduction is examined. To investigate the performance of the MR damper, a series of experiments was conducted in which the MR damper is used in conjunction with a recently developed clipped-optimal control strategy to control a three story test structure subjected to a one-dimensional ground excitation. The abil...
متن کاملBuilding Training Patterns for Modelling MR Dampers
A method for training patterns validation for modelling MR damper is proposed. The method was validated with two models based on black-box and semi-phenomenological approaches. An input pattern that allows a better identification of the MR damper model was found. Including a frequency modulated displacement and increased clock period in the training pattern, the MR damper model fitting is impro...
متن کاملRotary bistable and Parametrically Excited Vibration Energy Harvesting
Parametric resonance is a type of nonlinear vibration phenomenon [1], [2] induced from the periodic modulation of at least one of the system parameters and has the potential to exhibit interesting higher order nonlinear behaviour [3]. Parametrically excited vibration energy harvesters have been previously shown to enhance both the power amplitude [4] and the frequency bandwidth [5] when compare...
متن کاملH∞-PD Controller for Suspension Systems with MR Dampers
In this paper, we consider the implementation of a static H∞ output feedback controller to a quarter vehicle suspension system with a semi-active magnetorheological fluid (MRF) damper. Unlike most of the existing literature, all the states in the equation of motion are relative displacements and velocities between sprung, unsprung masses and road disturbance instead, in addition the input to th...
متن کاملStudies 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...
