In this article, the prototyped magnetorheological (MR) damper with internal solenoid based on Bingham modified model of MR damper is presented and experimentally tested on a real passenger car. The rolling-lobe type of the existing air spring was replaced with a cylinder-tube type and it was integrated with the MR dampers in order to save the mounting space. The forces generated by the semi-active dampers during valve operation are also measured. In this paper, to use Bingham modified model, an eleven degrees of freedom (DOFs) suspension system (four for four wheels, three for the body displacement and its rotations and the last four for passengers) has been modeled. The results of experiment are analyzed for comfortable driving and road holding. Comparisons between the results from the vehicle model and the experimental were good and acceptable. The most important features of the fabricated MR damper are low cost of production and simple structure.
