Simulation of dredging processes of a cutter suction dredger

Dredging simulation is of great significance to the development of dredging engineering technology of harbor, waterway, rivers, lakes, etc. The design and implement of the dredging simulation system are introduced. The modeling and key techniques for the virtual reality of construction site, the movement of dredge vessel, the soil cutting of cutter, and the hydraulic transport of sand in a pipeline, etc., are discussed. The cutter suction dredger simulator with a multi-channel round screen has been put into operation and produced good results.
