Problems solved by technology

[0003] At present, the sensors that combine the heeling moment component of the hull with the longitudinal force and lateral force components of the hull have many disadvantages, such as mutual interference, installation failure to reach the specified position, and a certain component of the sensor not reaching the required range or a certain value. If the vector path is too large, the measured hydrodynamic force needs to be converted again or the measurement accuracy is inaccurate
In addition, in the heeling moment measurement, in order to make the ship model heel, the method of padding the fixed angle block on the installation base of the ship bottom also brings great inconvenience to the installation and measurement of the test

Abstract

The invention provides a ship model heeling locking device. Another technical scheme of the invention is to provide a torque measuring method. A torque sensor is mounted on the rotating shaft, so thatthe problems of transverse inclination locking, transverse inclination torque measurement and the like in maneuverability four-degree-of-freedom modeling are solved. According to the device, the problem of convenient adjustment of the heeling angle is solved, the problem of measurement precision of the heeling moment is solved, and the device is a basis and a key point for high-precision measurement of the ship heeling moment, and is beneficial to improving the technical level of ship hydrodynamic tests. According to the device provided by the invention, the conception is ingenious, the structure is simple, the process performance is excellent, the operability is high, common parts are ingeniously combined to realize a ship heeling moment measurement function, a foundation for high-precision measurement of the ship heeling moment is laid, and the ship hydrodynamic test technology in China is improved.

Description

technical field [0001] The invention relates to a device suitable for heel locking and moment measurement and a measurement method using the device, in particular to a test device for measuring the heeling moment of a ship model and a measurement method using the test device, belonging to the ship Hydrodynamic measurement field. Background technique [0002] Maneuverability is one of the very important performances of a ship, which is related to the operational safety of the ship, and accurate performance prediction can reduce the risk of ship maneuvering. In the ship development stage, due to the change of ship shape, the increase of the center of gravity of the ship and the high speed, the traditional three-degree-of-freedom steering motion mathematical model including surge, sway, and roll cannot meet the needs of steering prediction. The four-degree-of-freedom mathematical model of the maneuvering motion within and the measurement of all hydrodynamic derivatives are the...
