| Abstract: | In order to effectively and accurately calculate the dynamic motions of underwater towed system,this paper constructs a dynamics model taking into account the effect of air,and develops a modified finite difference method to produce accurate,stable solutions for numerical simulation.Both numerical results and experimental data show that the model is more accurate in calculating the motion and tension of underwater towed cables and more trusty in predicting the security of two-towed system. |
