Abstract

The invention provides a method for simulating an inland river pushing fleet, which includes: determining the coordinate origin of the fleet coordinate system and the center of gravity of the fleet according to the fleet parameters; combining the coordinate origin and the center of gravity into one point to obtain the simplified four-freedom of the fleet degree motion equation; calculate the inertial force and viscous hydrodynamic force of the ship according to the length of the pusher and barge, the width of the pusher and barge, the draft of the barge and pusher, and the square coefficient of the ship; calculate the fleet according to the inertial hydrodynamic force and viscous hydrodynamic force of the ship The additional mass of the propeller; calculate the thrust of the propeller and the rudder force of the ship according to the rotational speed, diameter, advance speed, wake coefficient and thrust coefficient of the ducted propeller; substitute the additional mass, propeller thrust and rudder force into Runge Kuta to calculate the ship The acceleration and speed of the fleet; the simulator simulates the navigation of the real inland river pushing fleet according to the acceleration and speed of the fleet. The invention regards the pusher boat and the barge as one ship, fully considers the influence factors of the inland river environment, and realizes the simulation of the inland river pusher fleet.

Description

technical field [0001] The invention relates to the technical field of ship simulation, in particular to a method for simulating an inland river pushing fleet. Background technique [0002] As an advanced teaching method, ship simulator has been used in navigation teaching and crew training in our country for a long time. [0003] The inland river pusher fleet has shallow draft, good maneuverability and low operating cost, and is an indispensable carrier in inland river transportation. When the fleet operates in inland rivers, the requirements for maneuverability are relatively high, so some fleets use the ducted propeller system with double reverse rudders as the fleet's maneuvering and power system to ensure its maneuverability. [0004] Projects for river pusher fleets are missing from current ship simulators. Contents of the invention [0005] The invention provides a method for simulating an inland river pushing fleet to overcome the above technical problems. [00...
