Dynamic configuration simulation of multi-branches towed array system

The underwater multi-branch towing cable array is an advanced detection tool widely utilized across various fields, including industry and scientific research. Therefore, studying its operational behavior and nonlinear hydrodynamic characteristics is essential. In this paper, we develop a multi-branch towing cable array model to analyze the primary forces acting on the Control Bird, alongside conducting dynamic analysis for each connected buoy. An effective and reliable method is explored for measuring the formation of the cable array and the fluctuations in tension. This paper proposes and derives a relative current velocity method (RCVM) that improves analysis efficiency. The study evaluates the method's reliability in modeling the normal operation of an underwater multi-branch towing system. Additionally, sensitivity analyses are conducted to examine the system's response to various factors under steady-state and dynamic conditions. The findings offer valuable insights and references for practical engineering applications.
