Comparison of vibration control performance between flow and squeeze mode ER mounts: Experimental work

This paper proposes two different electrorheological (ER) mounts and compares vibration control performance. Dynamic models of flow and squeeze mode mounts are formulated and design parameters are determined by considering a static load of 200 kg. After manufacturing two ER mounts, the field-dependent displacement transmissibilities are evaluated in frequency domain. A simple sky-hook controller is then designed to attenuate the imposed vibration and the controller is experimentally realized. Vibration control responses are evaluated in frequency domain and compared between the flow and squeeze mode ER mounts.
