Modeling of magnetorheological mounts in various operation modes

Recent advances in the research of magnetorheological/electrorheological cated the opportunities for smart fluid based devic es utilizing more than one operation mode. As such, the purpose of the present research is to draw attention to the existi ng models of magnetorheological (MR) mounts o three fundamental operating modes, namely, the flow mode and the squeeze mode, and to highlight the po tential applications of these modes in hydraulic mount applications. The refore, in the paper the authors focus on recent ap plicatio fluids in that domain, and then proceed to summariz ing the modeling principles for the two operation m odes followed by a finite-element magnetostatic analysis of the mount's magnetic circuit, parameter sensitivity study and exempl ary nume ical simulations of each mode. The simulation results ar e converted into the frequency domain and presented in the form of dynamic stiffness and damping vs. frequency plots, respectively.
