This paper presents two different types of electrorheological (ER) mounts that can support a static load of 200 kg. One is a flow mode type, and the other is a squeeze mode type. After analyzing the governing equations of motion, two ER mounts are designed and manufactured. The field-dependent displacement transmissibilities are evaluated in the frequency domain. In addition, vibration control responses of two ER mounts are experimentally investigated by implementing a skyhook controller.
