Special Issue Information

Dear Colleagues,

Semi-active magnetorheological (MR) actuators and dampers have been commonly used in diverse applications such as vehicular seat suspension, passenger car suspension, engine mount vibration control, medical rehabilitation, robotics, or anti-earthquake structures. However, various factors, namely durability, temperature operating range, weight, cost, etc., have delayed the progress and the commercialization of the technology in certain areas. Therefore, it is necessary to focus on developing novel designs of MR dampers and actuators to meet the most stringent requirements of industrial practice. Therefore, the goal of this Special Issue is to cover the novel designs and applications of semi-active MR dampers and actuators. Theoretical inquiries presenting models capable of predicting the behavior of such devices and preferably supported by experimental studies are also welcome. Finally, the editors would like to invite research studies documenting recent progress in developing dedicated application-oriented MR fluid formulations.

We kindly invite you to submit a manuscript(s) for this Special Issue. Full papers and topical reviews are all welcome.

Magnetorheological (MR) fluids have been known to react to magnetic fields of sufficient magnitudes. While in the presence of the field, the material develops a yield stress. The tunable property has made it attractive in, e.g., semi-active damper applications in the vibration control domain in particular. Within the context of a given application, MR fluids can be exploited in at least one of the fundamental operating modes (flow, shear, squeeze, or gradient pinch mode) of which the gradient pinch mode has been the least explored. Contrary to the other operating modes, the MR fluid volume in the flow channel is exposed to a non-uniform magnetic field in such a way that a Venturi-like contraction is developed in a flow channel solely by means of a solidified material in the regions near the walls rather than the mechanically driven changes in the channel’s geometry. The pinch-mode rheology of the material has made it a potential candidate for developing a new category of MR valves. By convention, a pinch-mode valve features a single flow channel with poles over which a non-uniform magnetic field is induced. In this study, the authors examine ways of extending the dynamic range of pinch-mode valves by employing a number of such arrangements (stages) in series. To accomplish this, the authors developed a prototype of a multi-stage (three-stage) valve, and then compared its performance against that of a single-stage valve across a wide range of hydraulic and magnetic stimuli. To summarize, improvements of the pinch-mode valve dynamic range are evident; however, at the same time, it is hampered by the presence of serial air gaps in the flow channel. Full article
