Abstract

The invention provides a three-degree-of-freedom ship navigation posture simulation device. The device comprises a platform face, two platform racks, two stand columns, a shaft sleeve, a rotary table, a supporting sleeve, a motor support, a linear stepping motor, a harmonic reducer, a stepping motor fixing base, a motor shaft sleeve, a rigid coupling, a deep groove ball bearing, a connecting base, a connecting head, a gasket, a lining plate, a limiting post, a protective cover, a chassis and the like. By means of the three-degree-of-freedom ship navigation posture simulation device, wide-range simulation rotating motion of the navigation posture of a ship is made; besides, the stepping motor is used as a servo mechanism, and thus the simulation precision of the device is greatly improved. The three-degree-of-freedom ship navigation posture simulation device further has the advantages that energy consumption is reduced, reliability is high, visualization of the navigation posture of the ship is improved, and further study and research are facilitated.

Description

technical field [0001] The invention relates to a ship navigation attitude simulation device, in particular to a three-degree-of-freedom ship navigation attitude simulation device. Background technique [0002] Ship motion control has always been a national key topic. Ship motion control simulation system can be divided into three categories, namely single-machine simulation, double-machine simulation and physical simulation. Physical simulation is to use the ship model instead of the real ship to carry out various control experiments of ship motion, such as the influence of roll control and autopilot on the ship attitude information. The semi-physical simulation system of ship motion adopts the simulation method combining the physical object and the mathematical model, which can greatly save manpower, material resources and time, and truly reproduce the motion posture of the ship. [0003] The China Ship Science Research Center uses a cylinder with a diameter of 2 meters ...
