Dredging Simulation For A Trailing Suction Hopper Dredger

China has a wide territory and abundant water resources with long coastline and numerous harbors. Rivers, lakes and reservoirs scatter all over the country like stars in the sky. But currently a huge amount of sediment deposited there has caused severe problems and need to be dredged. Dredging is one of the effective engineering measures to control floods and improve navigation, irrigation conditions and environment.A trailing suction hopper dredger is one of the most popular dredging tools for regulation of waterway and harbors. It is a large self-propelled and self loaded dredger which can be used in wide water area such as an estuary or a river mouth. It is adaptive economical, it is widely used in large dredging projects in most countries in the world. The structure and the working process of a trailing suction dredger are complex, and the working environment and the material to be dredged vary very much. Improving the working character and the efficiency of trailing suction hopper dredgers will greatly increase the production, save power and bring more interests for dredging industry.This dissertation firstly discusses the basic structure of trailing suction hopper dredgers, then establishes the mathematical model of dynamic process of trailing suction hopper dredgers and the model of compensator of wind and wave, develops a set of real time simulation software using OOP Visual C++, MFC, Delphi and ActiveX component technology, and simulates the different dynamic characters for different working situations. This work helps the dredging teaching and dredging research, and also benefits the technicians to master the character of dredging equipment and ensures the safety and efficient operation.
