Study on smart damper in suspension system of tracked armored vehicle

Magnetorheological fluid (MRF) is a kind of important actuating material of smart material. Due to its virtue of fast response time, outstanding theological effect, less sensitive to contaminants and connecting with a computer easily, it is a new kind of vibration control device and has a wide application prospect of the anti-vibration domain. According to the character of magnetorheological device, combining the principles Of magnetic circuit design of magnetorheological device are determined. On the basis of summarizing of the mechanical and structure characters of MRF device, a shear-valve actuator whose cylinder rod is double out is designed, the magnetic circuit calculation method of the actuator is discussed. We think that magnetorhological dampers will be an ideal component of active vibration control in tracked armored vehicle suspension system by the reason of simple structure, small volume, energy saving, rapid response and smooth damping. In the paper a review has also been made about developi ng magnetorheological damper.
