Abstract

The invention provides a center of buoyancy measuring apparatus and method of an irregular underwater vehicle. The irregular underwater vehicle is arranged underwater, the vehicle achieves balance under the common effect of the self buoyancy, the self gravity, the gravity of a fixedly-connected tool, and a sensor acting force, a reference coordinate system is established by regarding a certain point of the center of buoyancy measuring apparatus as the origin, buoyancy and center of buoyancy parameters of the vehicle are obtained through calculation according to the static equilibrium principleand the static moment equilibrium principle through acquisition of output signals of weighing sensors by employing a three-point measuring method.

Description

technical field [0001] The invention relates to the field of unmanned underwater vehicles, in particular to a device and method for measuring the center of buoyancy of irregular underwater vehicles. Background technique [0002] Underwater vehicles have been widely used in intelligence collection, battlefield survey, anti-submarine warfare, ocean survey and other tasks, and have become one of the important research directions of national defense construction and ocean development in all countries in the world. For a high-speed underwater vehicle, if its weight and buoyancy center position are not properly handled, it will be difficult to adjust its navigation direction and attitude, which will easily cause the vehicle to deviate from the track or fail to hit the target. Therefore, it is very important to accurately measure the position of the center of buoyancy. [0003] Usually the unmanned underwater vehicle is irregular in shape and the mass distribution is uneven, and t...
