Parameters Optimization of Trailing Suction Hopper Dredger dredging Based on Genetic Algorithm

On the basis of systematic analysis and study on the dredging process of trailing suction hopper dredger,the process of trailing suction hopper dredger to improve the dredging efficiency by adopting controlling of dredging parameters is mainly targetd to.Taking the soil and other factors into account,a model of hopper process is presentd,combined the drag-head model with the hopper model.Based on this model,objective function is put forward and applied to GA for simulation optimization.Lastly,data measured on "Xinhaifeng" trailing suction hopper dredger is simulated and validated,showing that controlling dredging parameters could improve dredging efficiency.
