TL;DR: In this article, an optimal design of a passenger vehicle magnetorheological (MR) damper based on finite element analysis is presented, which is constrained in a specific volume and the optimization problem identifies the geometric dimensions of the damper that minimize an objective function.

TL;DR: In this paper, a cylindrical electrorheological (ER) damper is designed and manufactured by incorporating a Bingham model of an ER fluid which is commercially available, and a full-car suspension system installed with four independent ER dampers is then constructed and its governing equation of motion, which includes vertical, pitch, and roll motions, is derived.

TL;DR: In this paper, a nondimensional analysis for a mixed-mode magnetorheological (MR) damper is described. And the effects of the Bingham number and the hydraulic amplification ratio on the plug thickness and equivalent viscous damping coefficient are analyzed.

TL;DR: In this paper, a human simulated intelligent control (HSIC) scheme is developed to attenuate unwanted vibrations such as pitch angle acceleration in a half-car magnetorheological suspension system.

TL;DR: In this paper, the authors presented an optimal design for magnetorheological (MR) valves for minimizing the control energy to be applied to coils to control the pressure drop of the valves.
