Research on of Highline Cable of Alongside Replenishment at Sea

In view of the present situation of that has not had an overhead cable model can be used in the process of developing equipment of replenishment at sea, the multibody dynamics theory was introduced into the Highline modeling. Establish method of multi-rigid-body dynamics model, rigid-flexible-mixed-body dynamics model and the multi-flexible-body dynamics model of the rope was researched, and the calculation formulas of three kinds of multi body dynamics model of the rope were deduced. Combining with the actual situation, the concluded has been gain which are as follows: (1) The multi-body dynamics model of rope can simulate the Highline replenishment at sea; (2) multi-flexible-body dynamics model of the rope is more close to the actual structure of overhead cable than the other two multi-body dynamics models of the rope, the dynamic calculation results of which is closer to the actual situation, and it has certain use value in equipment development of the replenishment at sea.
