Abstract

In this study, a new hybrid mount with a moving-coil-type electromagnetic actuator is developed to reduce the vibration transmitted from naval shipboard equipment to the ship hull structure. The detailed design of the hybrid mount is determined through several design stages with electromagnetic numerical analysis using Maxwell software. The hybrid mount, which combines a rubber mount with an electromagnetic actuator, has a fail-safe function for shock resistance. The mount is fabricated and tested using a universal testing machine to check the design specifications. Finally, control tests are carried out on the hybrid mount to confirm its performance and applicability.

이 연구에서는 함정탑재 장비의 진동으로부터 기인되는 고체음의 저감을 목표로 새로운 형태의 복합형 마운트를 개발하였다. 수동형 마운트와 비접촉식 전자기식 작동기 또는 관성력형 작동기로 구성된 복합형 마운트가 우수한 성능을 보유한다는 선행연구 결과를 바탕으로 이 연구에서 개발된 복합형 마운트는 기존의 검증된 수동형 고무마운트와 전자기식 작동기를 비접촉식으로 결합한 형태이며, 내충격 성능을 고려하여 설계하였다. 먼저 장비로부터 유발된 진동이 외부로 전달되는 성분의 차단에 대해 복합형 마운트의 효과적인 구성요소 배치형식을 제안하였으며, 여러 설계인자를 고려한 초기 설계안을 제시하고, 마운트 설치 시 문제원인이 될 수 있는 내충격 성능을 고려한 최종 설계를 수행하였다. 설계된 복합형 마운트를 제작하고, 실험을 통해 성능을 검토하였다.
