Design and Test of a Magneto-Rheological Mount Applied to Start/Stop Mode of Vehicle Powertrains

In order to overcome the disadvantage of vehicle ride comfort caused by large vibration and torque excitation of vehicle engine in start/stop mode, a flow mode magneto-rheological (MR) mount is designed for low frequency working conditions. Based on the analysis on the influence of exciting current...
