Simulation of an MR squeeze-mode damper for an automotive engine mount

The paper summarises the simulation study of a magnetorheological damper prototype operated in squeeze mode (MRSQD). The aim of the study is to show that the MRSQD can be effectively employed in the engine mount for vibration reduction. The material covers description of the device and selected simulation results which present: the performance figure of the MRSQD complemented by FE calculations of the magnetic core, time histories of the current in the control coil under the harmonic piston motion and the constant-voltage supply conditions, plots of force vs. piston displacement and time histories of the piston displacement in an automotive engine mount for various current levels in the control coil.
