Research On The Scope Of Port Braking Waters

In the Design Code of General Layout for Sea Ports,it has certain limitations to plan braking water’s scale according to the rule because it is not detailed enough about the scale of port braking waters.In this paper,the braking performance of ship navigating in the port waters has been researched by the ship maneuvering motion simulation systems,a reference for layout the scale of the port braking waters can be provided by analysising the experiment datas.Based on the ship mathematical model of MMG,it uses MATLAB to analysis the ship maneuvering motion simulations in port.After the feasibility of simulation system is validated by patch test datas,which can be used to research the braking performance.For a example of YanTian port,the ship braking simulation program has been designed combined with the experimental condition selection principle in the full consideration external factors such as port hydrology,meteorology,channel conditions,incoming ship performance.Ship braking parameters are obtained through the simulations.Based on the non-linear curve fitting,braking area of the ship is obtained.And it gives out the relation between the influencing factors and the brake braking parameters by using the method of regression analysis.In this paper,the method has the advantage of engineering cost saving,and the conclusion can provide reference for port in practical design.
