Dynamic Simulation of a Multi-Cable Underwater Towed System

摘要

In this paper, a numerical method for dynamic simulation of a multicable underwater towed system is proposed. The system consists of a tow cable, a towed body and two arrays. The equations of motion for cables are based on Ablow and Schechter (1983) and the six-degre-of-freedom ordinary differential equations are used in analyzing motion of a towed body. The boundary conditions of the system are derived. the numerical scheme is based on a finite difference method. A number of runs are simulated including maneuvers such as turns and sudden velocity changes. The results show that the numerical method is stable in the whole range of simulation and effective in predicting the motion of a multi-cable underwater towed system.
