Modeling of Three-Dimensional Dynamical Behavior of Ropes Used in Fishery Based on R Language

Ropes are widely used in various kinds of fishing gear. In this paper, a numerical method is presented which is competent in predicting the three-dimensional dynamic behavior of cables. The dynamic behavior of cables were simulated using dynamical equations and R language. The method was based on the lump-mass and spring model and the implicit algorithm was applied to solve the stiff differential equations. The mathematics-mechanical analysis was provided on the basic characteristics of the model. The R platform was used in programming, simulation, and visualization of the results. The three-dimensional dynamic behavior of cables in different examples were presented successfully and verify the effectiveness of this method, and the motion process was consistent with the observed data in the ocean.
