Insight into Magnetorheological Shock Absorbers

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.

Presents the magnetorheological fluid theory and its applications in automotive magnetorheological dampers Highlights common configurations of flow-mode magnetorheological shock absorbers, which are considered to be particularly interesting by the automotive industry for controlled chassis applications Offers a math-based analytical model of an exemplary MR fluid device, a flow-mode monotube damper, which is needed Includes supplementary material: sn.pub/extras
