Abstract
This article proposes a new hybrid active mount featuring piezostacks and rubber element that can provide high performance in vibration control. After describing the configuration and operating principle of the proposed mount, appropriate rubber element and piezostack are designed and manufactured. Subsequently, dynamic characteristics of the piezostacks and the rubber element are experimentally identified. A two-degree-of-freedom control system, in which the hybrid active mount is installed with a supported mass of 100 kg, is then constructed for evaluating vibration control performance. To attenuate actively the vibration transmitted from the base excitation, a robust sliding mode controller is formulated by considering parameter uncertainties. The controller is then experimentally realized and vibration control performances of the proposed mount system are evaluated in both time and frequency domains.
