The multi-body dynamics theory is used to establish a highline model, because there is not any appropriate highline model for research on sea replenishment equipment. A method for establishing multi-rigid-body dynamics model, rigid-flexible-mixed-body dynamics model and multi-flexible-body dynamics model of rope is studied. Three rope models are used to simulate the highline, and the sea dry cargo replenishment transverse process is simulated with ADAMS. The results show that the development trend of velocity, force, angular velocity and torque for three models in simulation process is basically consistent with the actual mechanical properties of highline cables, meaning that the multi-body dynamics model of rope can simulate the highline replenishment at sea;the multi-flexible-body dynamics model of rope is more closer to the actual structure of highline cable compared to the other twokinds of multi-body dynamics models of rope.
