Stabilization method and system for small and medium-sized ships

Abstract

The invention provides a stabilization method and system for small and medium-sized ships. The method comprises the following steps of S1, symmetrically arranging two propelling mechanisms in the middles of the left side and the right side of a ship body; S2, establishing the mechanical model of the ship; S3, calculating the kinetic equation of the mechanical model; S4, collecting the data of theplurality of groups of ships in a balanced state under different conditions; S5, collecting ship operation environment data and ship operation data during ship operation, and when [theta] is larger than 10 degrees, pushing force f(t) needing to be provided by a pushing mechanism when the ships need to recover balance at the moment is obtained through calculation; and S6, allowing the pushing mechanism on the inclined side of the ship to start work, applying the pushing force with the size of |f(t)| to the ships, wherein the ships are made to recover balance. According to the stabilization method and system for the small and medium-sized ships, inclination of the ships is corrected in time, and the stability and safety of ship navigation are effectively improved.

Description

technical field [0001] The invention relates to the field of ship control. More specifically, the present invention relates to a method and system for anti-rolling of small and medium-sized ships. Background technique [0002] With the economic globalization, the trade volume between countries is also rising. The mode of transportation between countries is currently dominated by ships. In order to ensure the safety of sea personnel during long-distance transportation and the comfort of passengers on short-distance parades, The anti-rolling work of the ship is indispensable. The traditional anti-rolling methods rely more on the design of the ship itself, by increasing the hull damping and lowering the center of gravity, etc., but these traditional anti-rolling methods have some disadvantages. If the anti-rolling method is increased by increasing the damping of the hull, it will reduce the flexibility of the ship's steering when sailing, and it will not be possible to quickly...

[0002] With the economic globalization, the trade volume between countries is also rising. The mode of transportation between countries is currently dominated by ships. In order to ensure the safety of sea personnel during long-distance transportation and the comfort of passengers on short-distance parades, The anti-rolling work of the ship is indispensable. The traditional anti-rolling methods rely more on the design of the ship itself, by increasing the hull damping and lowering the center of gravity, etc., but these traditional anti-rolling methods have some disadvantages. If the anti-rolling method is increased by increasing the damping of the hull, it will reduce the flexibility of the ship's steering when sailing, and it will not be possible to quickly avoid the obstacles in front of it. However, the anti-rolling method by reducing the center of gravity will reduce the load of the ship and the capsizing probability of the ship. will also rise
