초록

본 논문은 윈치드럼과 함께 구성되어 있는 수중 케이블의 거동을 해석하기 위해 개발된 조출 모델링을 소개한다. 케이블의 수중 거동은 장력만 영향을 준다고 가정한다. 이러한 가정은 직진 거동을 하는 함정에 의해 예인되는 수중 케이블 거동을 해석하는데 적합하다. 수중 케이블은 절점 위치유한 요소법으로 차분한다. 이 수치기법은 기하학적 비선형성을 표현할 수 있기 때문에 대변형을 동반하는 수중 케이블의 거동 예측에 적합하다고 알려져 있다. 본 논문은 실제 역 실험에서 계측된 수중 예인케이블의 심도 정보를 활용하여 수치 기법의 타당성을 확보한다.

In this paper, we introduce a newly developed winding model to simulate the motion of underwater cable consisting of winch drums. It is assumed that only tension affects the underwater cable motion. This assumption is suitable for simulating the underwater cable motion towed by a navel vessel in a straight ahead maneuver. The underwater cable is discretized using Nodal Position Finite Element Method. This numerical method is known to be suitable for predicting the underwater cable motion with large deformation because it can express geometric nonlinearity. In this paper, the validity of the numerical method was secured by comparing it with the depth information of towing cable measured through sea experiments.
