Simulation of underwater dragging system's steady cable shape

The underwater dragging system is widely used in all kinds of field, such as observing geography at the bottom of sea, the basic hydrology data collections, hunting submarines, sweeping the torpedo and torpedo etc. Now the research on the underwater cable is limited in 2D model. And there is so much relevant material about these researches. On the foundation of analyzing and studying the kinetics and dynamics of underwater dragging system, the two dimension mathematic models about planar shape and tension of the underwater dragging system of the AUV were set up. At the end, the model was programmed through the calculation about the underwater dragging system with variety navigational speed and different hydrophone, comparing the external form and suffering force. Then a conceive of adding obstruction combining the dragging system's characteristics was suggested, and the results of the conceive were put out with certain engineering value.
