Abstract

The invention belongs to the technical field related to the measurement of the hydrostatic performance of a ship model, and discloses a hydrostatic performance measurement device and a measurement method of a ship model. The second rotating shaft and the connecting plate, wherein: the fixed platform is provided with a rigid lifting structure, and the upper end of the lifting platform is connected with the lifting structure, so that the lifting platform moves up and down driven by the lifting structure ; The six-component force dynamometer is located at the lower end of the lifting platform; the upper end of the angle platform is fixedly connected with the six-component force dynamometer, and the lower end of the angle platform is rotated by the second The shaft is connected with the connecting plate; the connecting plate is used for connecting with the ship model. The application can accurately simulate different tilting states and drafts of the ship model, and the hydrostatic performance of the ship model under different experimental conditions can be obtained through the sextant dynamometer and the structure of the ship hull.

Description

technical field [0001] The invention belongs to the technical field related to the measurement of the hydrostatic performance of a ship model, and more particularly, relates to a device and a measurement method for the hydrostatic performance of a ship model. Background technique [0002] Buoyancy and stability are one of the most important concepts in the experimental teaching of ship and ocean engineering. The textbooks related to the principles of ship statics give a principle introduction to the method of finding buoyancy under any floating state, but there is no one that can A device for intuitively measuring buoyancy experiments. Hydrostatic curve is a general term for various curves related to draught such as buoyancy elements, initial stability elements and ship shape coefficient when the ship is in a static and positive floating state, including volumetric displacement, weight displacement, buoyancy coordinates, waterline area, etc. A set of curves of the relations...
