Abstract

The invention relates to a planar motion mechanism for water ship model maneuverability test. The planar motion mechanism comprises a trailer, wherein a swaying motion mechanism is arranged on the trailer; an adjusting mechanism is arranged on the swaying motion mechanism; front and back symmetrical balance force-measuring mechanisms which are connected through a transverse beam are fixedly arranged on a ship model; a support rod of the adjusting mechanism is fixedly connected with the transverse beam downwards; the swaying motion mechanism is used for driving the ship model to sway under the driving action of a motor; the adjusting mechanism is used for adjusting the immersion depth of the ship model in cooperation with a nut and a sleeve, and drives a ship model bow to move through an electric cylinder; and the initial transverse dip angle of the ship model is adjusted through the balance force-measuring mechanisms. Through adoption of planar motion mechanism, the swaying, bow swaying and composite movement of the ship model are realized effectively; different transverse dip angles can be set; and fluid dynamic test researching of the ship model while the water surface and near-water surface oscillate periodically and transversely is prompted. The planar motion mechanism is convenient to operate, and has high test efficiency.

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...
