摘要：In this study, the part dynamics of the midwater trawl were modeled and simulated using mechanical equations and R language. A lumped mass method was used to model the dynamical behavior of a net in steady flow. And the implicit algorithm was developed to solve the stiff differential equations. The programming, simulation and visualization of the modeling were based on the R platform. The part dynamics of the trawl in the sea water were presented successfully, and the motion process conformed well to the observed data in the ocean.
