Naval vessel sea state dynamic simulator

Abstract

When performing a task at sea, a naval vessel often comes across typhoons or sea waves, or is hit by shells during a fight, so that a naval vessel body tilts at a large angle, and under a serious condition, the naval vessel body even can overturn. In order to predict the tilting range borne by the naval vessel in advance or simulate sea states which can be generated when the naval vessel performs the task, the invention provides a naval vessel sea state dynamic simulator. According to the naval vessel sea state dynamic simulator disclosed by the invention, a method that a three-freedom degree motion platform and a six-freedom degree motion platform are overlaid is adopted; electric-hydraulic servo driving is used; the six-freedom degree motion platform is arranged at the top and the three-freedom degree motion platform for supporting is arranged at the bottom; under the control of an electric-hydraulic servo system, the two platforms are mutually matched, so that the various sea states which probably appear can be simulated; finally, the sea states of 0-9 levels, which can be generated when the naval vessel performs the task at a sea level can be simulated. The naval vessel sea state dynamic simulator disclosed by the invention can have an important effect of simulating detection in the process of designing and manufacturing of the naval vessel.

Description

technical field [0001] The invention relates to a simulation device, in particular to a ship sea state dynamic simulator. Background technique [0002] With the continuous deepening of the complexity of today's society, the navigation industry is becoming more and more prosperous, followed by the development of the shipbuilding industry, but now the traditional shipbuilding technology can no longer meet the requirements, and the more important modern advanced technology belongs to the simulation technology , and the most widely used in the shipbuilding industry is the ship motion simulation platform. Various sea conditions that the ship may encounter can be simulated in the laboratory, and then problems can be found, so as to facilitate the transformation of the ship by research designers. With the development of the shipbuilding industry, technicians have higher and higher requirements for real-time ship simulation, so the research on ship physical simulation test system i...

Problems solved by technology

However, the space of the parallel mechanism is small, and it can only simulate the state of the ship in the sea state of 0~6, and cannot simulate the movement of the ship in the state of strong winds and waves or being hit by shells, which limits the level of dynamic simulation of the ship.
