Abstract

The invention relates to a planar movement mechanism used for the maneuverability test of a ship model on the water surface, which includes a trailer on which a sway movement mechanism is installed, and an adjustment mechanism is installed on the sway movement mechanism; force mechanism; the pole of the adjustment mechanism is fixedly connected to the beam downward; the sway movement mechanism drives the ship model to sway under the drive of the motor; Ship model yaw movement; adjust the initial heel angle of the ship model through the balance force measuring mechanism. The invention effectively realizes the sway, yaw and compound motion of the ship model, and can set different heel angles, which promotes the hydrodynamic test research of the ship model with periodic transverse oscillation motion on the water surface and near the water surface, and is easy to operate and high in test efficiency. high.

Description

technical field [0001] The invention relates to the technical field of water surface ship model test equipment, in particular to a planar motion mechanism used for water surface ship model maneuverability tests. Background technique [0002] During the voyage, in order to prevent the fuel from running out and reach the destination as soon as possible, the ship usually tries to keep the ship sailing in a straight line at a certain speed, so the ship is required to have good heading stability; when obstacles are found ahead on the scheduled route, In order to avoid collisions, the ship should change its course and speed in time, and the ship is required to have good slewing and head-turning performance. To sum up, the performance of a ship to maintain or change its speed, course and position is defined as ship maneuverability. The maneuverability of a ship can be evaluated by analyzing and solving the equations of motion, which include a large number of hydrodynamic coefficie...
