A magnetorheological fluid (MRF) is a smart composite suspension composed of nonmagnetic liquid and soft magnetic particles. Carrier fluids can considerably influence the performance MRFs; therefore, to investigate effect carrier on MRFs, an SO/IL-MRF was prepared by mixing ionic (IL) with silicone oil (SO) in this study. Three types MRF samples were for experiments (pure SO, pure IL, SO/IL). A...

A new semiactive control strategy for seismic response reduction using a neurocontroller and a magnetorheological (MR) fluid damper is proposed. The proposed control system adopts a clipped algorithm which induces the MR damper to generate approximately the desired control force. The improved neuro-controller, which was developed by employing the training algorithm based on a cost function and ...

To improve the performance of vehicle suspension, this paper proposes a semi-active suspension with magnetorheological fluid (MRF) damper. We designed an optimized fuzzy skyhook controller grey wolf optimizer (GWO) algorithm base on new neuro-inverse model MRF Because inverse damper is difficult to establish directly, Elman neural network was applied. The novelty study application for vibration...

A smart liquid gating membrane is a responsive structural material as pressure-driven system that consists of solid and dynamic liquid, responding to the external field. An accurate prediction rheological mechanical properties important for designs membranes various applications. However, high predicted accuracy by traditional sequential method requires large amount experimental data, which not...

The development of control systems for a two degreeof-freedom vibration suppression system using a magnetorheological (MR) fluid damper is the subject of this paper. It is assumed that system encounters impulsive disturbance forces. The objective is to use the (MR) fluid damper for the position control and vibration suppression of the payload. The control force is generated by regulating the el...
