Zhang, X., Wang, X., Li, W. and Kostidis, K. 2009, 'Variable stiffness and damping MR isolator', in 11th Conference on Electrorheological Fluids and Magnetorheological Suspensions, 25-29/08/2008, Dresden Germany, Journal of Physics, vol. 149, p. 012088.


This paper presents the development of a magnetorheological (MR) fluid-based variable stiffness and damping isolator for vibration suppressions. The MR fluid isolator used a sole MR control unit to achieve the variable stiffness and damping in stepless and relative large scope. A mathematical model of the isolator was derived, and a prototype of the MR fluid isolator was fabricated and its dynamic behavior was measured in vibration under various applied magnetic fields. The parameters of the model under various magnetic fields were identified and the dynamic performances of isolator were evaluated.
