Abstract Magnetorheological (MR) dampers with bypass arrangements and combined annular-radial fluid flow channels have shown superior performance compared to conventional MR single annular/radial gaps. Achieving a higher controllable dynamic force range low off-state but high on-state damping is yet significant challenge for developing payload ground vehicle suspensions. This paper presents the...

Abstract Magnetorheological (MR) fluid based dampers have been established as an alternative to classical hydraulic with proportional electromagnetic valves under vibration processes which demand adaptive damping forces. Almost all MR-dampers are spatially 1-degree-of-freedom (DOF) dampers, having only one axis or direction of force generation. In many technical applications there exist movemen...

The dispersed particles of magnetorheological fluid form stable chain-like clusters under the magnetic field, and show an effect of controllable flowability and shape. Based on this characteristic, using migration magnetic acted on the magnetorheological fluid, the object directional migration can be realized, and then the magnetorheological fluid forms levitation at the same time, which has li...

In light of the insurmountable sedimentation magnetorheological (MR) fluid, it is great significance to ensure performability an MR damper by introducing a sensing method for fluid settling, and key indicator identify health status critical. However, settling monitoring system can nowadays only function in laboratory with transparent non-magnetic tubes, which not qualified in-situ steel-made cy...

The Bouc Wen magnetorheological damper model has eight unknown parameters, and the mathematical expression of includes evolution quantity, absolute value term, exponential term differential equation, which complicates parameter identification. Researchers in related fields have made numerous attempts to solve problem that model's identification method is complex difficult implement. A combining...

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...
