In order to study the rheological characteristics of magnetorheological fluids, a novel approach based on the two-component Lattice Boltzmann method with double meshes was proposed, and the micro-scale structures of magnetorheological fluids in different strength magnetic fields were simulated. The framework composed of three steps for the simulation of magnetorheological fluids was addressed, ...

Combining shock and vibration isolation into a single isolation system package is explored through the use of an air spring in parallel with a controlled magnetorheological fluid damper. The benefits of combining shock and vibration isolation into a single package is discussed. Modeling and control issues are investigated and test and simulation results are discussed. It is shown that this hybr...

This paper puts forth an approximate solution for the effective free-energy function describing the homogenized (or macroscopic) magnetoelastic response of magnetorheological elastomers comprised of non-Gaussian rubbers filled with isotropic suspensions of either iron or ferrofluid particles. The solution is general in that it applies to N = 2 and 3 space dimensions and any arbitrary (non-perco...

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...

The extremum seeking controller (ESC) that minimizes the unknown performance index is applied to the control of SI (spark ignition) engines in the idle speed region. The proposed control system consists in the three parts, fuel-jet mount controller, ignition-timing controller and engine speed controller. The ESC applied to the engine speed controller should be modified in order to improve the e...

Magnetorheological (MR) materials and shear thickening fluids are both smart material and their combination could offer both MR and ST effects. This study looks at the properties and behaviour of magnetorheological shear thickening fluid (MRSTF) in particular whilst applied as a semi-active energy absorber. A device with two forms of varying vibration control has been created and measured. The ...
