چکیده
This paper aims to present a suspension control strategy for semi-active mount with variable damping utilizing smart magneto-rheological fluid (MRF), which will be applied in micro autonomous railway inspection car as primary protect the equipment from large vibration on rails. We proposed new multi-pole structure design (MR mount) that can provide both high force and wide band. Firstly, mathematical model of MR dynamics was derived; secondly, skyhook developed mount; finally, dynamic simulation problem using Matlab software constructed evaluate performance mount. The results showed greater isolation compared conventional passive mounts. In particular, absolute displacement, velocity, acceleration detector device were reduced by 83.33%, 77%, 70%, respectively. transmitted also decreased significantly, input oscillation (i.e., un-sprung mass oscillation). Specifically, half at excitation frequency 2-fold natural magnitudes higher frequencies.

A Rheological Model for Magneto-rheological Fluids
Magneto-rheological fluids (MRF) are suspensions of particles which can be magnetized. MRF exhibit fast, strong and reversible changes in their rheological properties when a magnetic field is applied. A commercially available damping system that takes full advantage of the controllable technology of MRF and delivers valveless damping control appeared on passenger vehicles in 2003. Further comme...
