Insight into Magnetorheological Shock Absorbers [Hardcover]

This book deals with magnetorheological fluid theory, modeling and applications of automotive magnetorheological dampers. On the theoretical side a review of MR fluid compositions and key factors affecting the characteristics of these fluids is followed by a description of existing applications in the area of vibration isolation and flow-mode shock absorbers in particular. As a majority of existing magnetorheological devices operates in a so-called flow mode a critical review is carried out in that regard. Specifically, the authors highlight common configurations of flow-mode magnetorheological shock absorbers, or so-called MR dampers that have been considered by the automotive industry for controlled chassis applications. The authors focus on single-tube dampers utilizing a piston assembly with one coil or multiple coils and at least one annular flow channel in the piston.

Introduction.- MR Fluids.- Configurations of MR Dampers.- Modelling of Control Valves.- Damper Modelling.- CFD Study of the Flow of MR Fluids.- Power Drivers.- Experimental Verification of an MR Monotube Damper Model.- Energy Harvesting MR Dampers.- Concluding Remarks.
