Logical analysis and diagnosis of the hydraulic system trouble for the drag-suction dredger;

This paper uses 3DS Max to build up a model of drag-suction dredger and develops the 3D view system with OpenGL library, which is based on VC++6.

A trailing suction hopper dredger is one of the most popular dredging tools for regulati.

A brief description of the dredge system design of drag suction dredger;

Optimum Hopper Capacity Selection for TSHD Based on the Cost Calculation;

To find the rule about the change of the mass center positions of a TSHD s draghead with time when working in different soil hardness of seabed under the function of swell compensator, a simulation model of TSHD is built based on a mathematical model, by using the software of ADAMS (Automated Dynamic Analysis of Mechanical Systems).

Overall design on a Lian Yungang 5000 m~3 drag suction dredger;

Dump door mounting for mud hold on drag suction dredger;

Estimation of dredging operation resistance of drag suction dredger;

Trailing suction hopper dredger plays an important role in growth and construction of port and waterway.

The paper expounds the major mathematical models that have been developed independently for trailing suction hopper dredgers to optimize their production and improve their working technology according to the changes of seabed.

After analyzing the dredging diesel updating for trailing suction hopper dredger that imported from abroad, this paper gives a demonstration of operation characteristics, application range, relevant technological problems and solvent of new machine type.
