Problems solved by technology

[0002]Because the working environment of unmanned boats is not easy to approach, it makes the research, development and testing of its hardware and software system more difficult
When the unmanned boat is working, it may cause the hull to capsize due to its internal failure or the inability to deal with an unforeseen environmental factor, and there are many devices on the unmanned boat that are expensive, so the overturning of the hull will cause huge losses

Abstract

The invention discloses a ship motion simulation method and a ship motion simulation system. The ship motion simulation method comprises the steps of collecting the mass, the moving speed, the moving direction, the rotating speed and the rotating direction of a ship; determining resultant force borne by the ship and resultant force torque of the resultant force to the gravity center of the ship according to the moving speed and the rotating speed; determining driving force and driving force torque of the driving force to the gravity center of the ship according to the water spraying angle, the position of a nozzle of the water spraying thrust device and the water spraying force; determining hydrodynamic force of the ship according to the driving force and the resultant force, and determining hydrodynamic force torque of the hydrodynamic force to the gravity center of the ship according to the resultant force torque and the driving force torque; establishing a navigation terrain model and a three-dimensional entity model of the ship; establishing a navigation environment model; and simulating the moving direction, the moving speed, the rotating direction and the rotating speed of the ship in the navigation environment model. Therefore, various parameters of ship navigation can be determined in real time, and the motion of the ship can be monitored in real time.

Description

technical field [0001] The invention relates to the field of ships, in particular to a ship motion simulation method and a ship motion simulation system. Background technique [0002] Because the working environment of unmanned boats is not easy to approach, the research, development and testing of its hardware and software systems become more difficult. When the unmanned boat is working, it may cause the hull to capsize due to its internal failure or inability to deal with an unforeseen environmental factor, and there are many equipment on the unmanned boat that are expensive, so the overturning of the hull will cause huge losses . Therefore, it is necessary to monitor the movement of the unmanned ship in the process of working in real time, as well as various parameters of its navigation, and then provide a basis for improving the performance of the unmanned ship. [0003] Therefore, the present invention provides a ship motion simulation method and a ship motion simulat...
