Abstract

The car ferry operating between the mainland and the island plays an important role on transportation of goods and passengers. Therefore, the improvement of efficiency and safety as well as economic factor are importantly considered in the development process of car ferry. Double-ended car ferry is already popularized because of its economic feasibility and convenience for passenger in Europe and developed countries, and the demand is booming in domestic. In this paper, dynamic characteristics of propeller shaft and strength in double-ended car ferry are analyzed using campbell diagram and modal analysis. Based on the analysis of dynamic characteristics, resonant phenomenon and critical speed are stable when occurring the propeller shaft vibration due to forward and reverse propeller shaft working.

육지와 도서를 연결하는 차도선은 교통수단 기능과 물자수송을 담당하는 중요한 역할을 하고 있다. 이에 따라 차도선의 효율성 증대와 안전성 향상 및 경제적 요건 등을 고려한 선박이 개발 중이다. 유럽에서는 승객의 편의성 및 경제성을 고려하여 양방향 차도선(Double-ended Car Ferry)의 개발이 활발히 진행 중이며 국내에서도 이에 대한 연구 개발이 필요하다. 본 연구에서는 유한요소법을 이용하여 차도선 제작 시 축계의 제작 및 강도의 문제를 Campbell Diagram 및 Modal 해석을 통한 동특성 분석을 하였다. 이를 통하여 양방향 차도선의 추진 방향 및 후진 방향 축계 작동 시 공진 현상 및 위험속도를 분석 결과 안정성을 보인 것으로 판단된다.
