Ship Motion Measurement System Analysis And Design

Mathematical model of ship motion has been a shipbuilding industry and maritime sector of interest issues, ship motion mathematical model has been widely used as a prediction of ship maneuvering characteristics and design studies of marine simulator core. Therefore, the mathematical model of ship motion quality will directly affect the performance of the prediction accuracy of the ship, thus affecting the accuracy of the ship's control; for ship motion simulation training system, will directly affect the simulation accuracy.The real test to study the ship mathematical model of ship maneuvering important means has always been the shipbuilding industry, the maritime sector of the pie. Test equipment for the ship before use more inertial and optical positioning equipment, with the compass and the meter device for, expensive equipment, less precision is not high degree of automation, resulting in less availability of test data real ship. Now, with the rapid development of science and technology, new components, new materials, new technologies have emerged, the establishment of a new type of ship motion measurement system, test data will help to improve the accuracy of the ship, the ship accurately reflect the true state under different conditions and handling. As China's economic strength improved, increasing research funding for the conduct of ship sea trials provided sufficient financing. "15" period, funded by the state built a Dalian Maritime University teaching and research training vessel "educating Kun 'round. Training on board ship at sea to establish a mobile laboratory, according to the ship motion data measurement requirements, the installation of a variety of navigation data measurement equipment, to constitute a complete set of advanced and ship motion measurement system provides equipment protection.This paper based on the ship motion measuring devices, and through the analysis of ship motion needed in the analysis of the measured parameters, relying on in the existing ship motion measuring devices, and discussed a ship motion of the measurement system, and in the light of the overall design of the scheme completed the major parts of the system establishment and test, through the real test have gathered a large number of test data, the application in ship motion model analysis, show the practical and the accuracy of the system.
