In this research, the effect of shape parameters such as number of magnet wire turns, spools, thickness of the gap, and pole length in a Magneto-rheological (MR) fluid damper is analytically investigated and the optimization of these parameters is done with response surface method (RSM) which is combined Neuro-Fuzzy method and Particle Swarm Optimization (PSO) algorithm. Since the electro-magne...

There are many ferromagnetic particles dispersed in carrier oil in magnetorheological fluids. Assuming Newtonian motion, the forces between particles of different radius, including magnetic interaction, viscous force and contact interaction, are obtained, and the corresponding model for motion of particles is proposed. Under an external magnetic field, the microstructures in bidisperse magnetor...

Magnetorheological (MR) dampers have received a great deal of attention due to their being a potential technology to conduct semi-active vibration control and it has become vitally important to describe the dynamic responses of these devices in an effective manner in order to develop successful control algorithms. To this end, a considerable effort has been devoted in the literature to study th...

Hard-magnetic barium ferrite (BF) nanoparticles with a hexagonal plate-like structure were used as an additive to carbonyl iron (CI) microparticle-based magnetorheological (MR) fluid. The morphology of the pristine CI and CI/BF mixture particles was examined by scanning electron microscopy. saturation magnetization coercivity values each particle measured in powder state vibrating sample magnet...

Magnetic materials such as magnetorheological (MR) fluids, and elastomers exhibit a broad change in their material properties, for example, viscosity storage modulus the presence of magnetic field. Studies related to MR fluid elastomer are extensively available. The brush, meanwhile, is less frequently explored understood. An brush defined by brush-like structures formed from chains particles e...
