| Abstract: | For damage to the spuds of cutter suction dredgers,a spud and soil model is set up with LS-DYNA,combined with the calculation of the environmental loads of winds,waves,currents,etc,to carry out numerical studies and contrast analysis of the anti-impact capacity of spuds.Suggestions are proposed for the safe use of spuds.The simulation result agrees well with the real case.The conclusions arrived shall have some guidance to the construction of cutter suction dredgers. |
