Harmonic analysis of a magnetorheological damper for vibration control
Semi-active control systems are becoming more popular because they offer both the reliability of passive systems and the versatility of active control systems without imposing heavy power demands. In particular, it has been found that magnetorheological (MR) fluids can be designed to be very effective vibration control actuators, which use MR fluids to produce controllable damping force. The ob...
متن کاملNonlinear Structural Control Using Magnetorheological Damper
This chapter provides an introduction to semi active control of base isolated buildings using magnetorheological (MR) dampers. Recently developed nonlinear control algorithms are discussed. First a fuzzy logic control (FLC) is designed to decide how much voltage is required to be supplied to the MR damper for a desired structural response. The FLC is optimized using micro genetic algorithm. A n...
متن کاملPreliminary Study of Modelling Dynamic Properties of Magnetorheological Fluid Damper
u(t) c 1 2 k 3 m f c Abstract A preliminary study was conducted to investigate numerical models that can be used to simulate the dynamic behaviour of a damper based on magnetorheological (MR) materials. Several articles presenting the results of experimental testing and mathematical modelling have been published recently. The goal for this study was to implement a selected model into the finite...
متن کاملControllable 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 کاملSemi-active vibration isolation of a quarter car model under random road excitations using Magnetorheological damper
Semi active control systems are becoming increasingly popular because they offer reliability of passive systems combined with high performance and versatility of active control systems but with low power consumptions. As Magnetorheological (MR) fluids can produce good controllable damping force under application of magnetic field, MR damper can be used as effective element in semiactive vibrati...
