초록

본 연구에서는 기존 고무마운트와 동일한 외부 형상을 갖는 능동마운트를 고안하고 진동절연 성능을 실험적으로 고찰하고자 한다. 압전작동기를 특징으로 하는 제안된 능동 마운트는 고성능 선박이나 자동차에서 사용되는 기계장치들의 진동을 절연하기 위해 적용될 수 있으며, 고무요소와 함께 구성되어 하이브리드 구조를 갖고 있다. 먼저 수동형 고무마운트의 동적 특성을 실험적으로 고찰하였으며, 고무마운트의 형상에 기초하여 능동형 마운트을 위한 고무요소가 제작되었고 2개의 스택형 압전작동기와 직렬로 연결함으로써 관성형 작동메커니즘을 구성하였다. 본 연구에서는 진동을 절연하기 위해 단순하면서도 현장 적용이 용이한 PID 제어기가 구성되어 비공진 고주파수 대역의 진동을 절연하기 위한 제어 실험에 적용되었다. 마지막으로 넓은 주파수 영역에서 진동제어 성능을 실험적으로 고찰하고 기존 고무마운트와 진동 절연 성능를 비교 평가하였다.

An active mount is devised in same geometric constraints with a conventional rubber mount. The proposed mount features the piezoelectric actuator which can be used to reduce the vibration at marine vessels or automotive vehicles. As a first step, a passive rubber mount is adopted and its dynamic characteristics are experimentally evaluated. Based on the geometry of the rubber mount, a rubber element for the active mount is manufactured and integrated with two piezostacks in series, in which the piezostack is operated as an inertial type of actuator. A conventional PID controller featured by the simple and easy implementation, is then designed to attenuate the non-resonant high frequency vibration transmitted from the base excitation. Finally, the control performances of a proposed active mount are evaluated in the wide frequency range and compared with those of the conventional rubber mount.
