Problems solved by technology

[0003] However, at present, there is no clear and standardized experimental device for testing the seakeeping test. Most of the seakeeping tests are carried out in the towing pool. When the trim angle is measured in waves, the ship model yaws, resulting in a deviation in the measurement angle, which affects the accuracy of the test results

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] A ship seakeeping test device shown in the figure is installed on a ship model 7 for testing its seakeeping, including a horizontal bar 1, a vertical vertical bar 2 arranged perpendicularly to the horizontal bar 1, and a The vertical sleeve 3 facing the upper end of the vertical bar 2, the limit plate 4 arranged on both axial sides of the horizontal bar 1, and two mounting seats 5 for supporting and installing the horizontal bar 1, the horizontal bar 1 and the vertical bar 1 The vertical bar 2 is integrally formed, and the limiting plate 4 is disc-shaped and integrally formed with the horizontal bar 1 . The bottom end of the vertical vertical bar 2 is fixedly connected with the middle upper part of the horizontal bar 1, and the axial ends of the horizontal bar 1 can respectively pass through the mounting seat 5 and abut against the outer ...

Abstract

The invention discloses a ship sea-keeping test device, which is arranged on a ship model and used for testing seakeeping performance of the ship model. The ship sea-keeping test device comprises a horizontal cross bar, a vertical stand bar arranged vertically to the horizontal cross bar, a vertical sleeve sleeving the upper end of the vertical stand bar, stop plates arranged at the two ends of the horizontal cross bars, and two installation bases for supporting and mounting the horizontal cross bars. The bottom end of the vertical stand bar is fixedly connected to the upper surface in the middle of the horizontal cross bar; and the axial two ends of the horizontal cross bar pass through the installation bases and abut against the outer walls of the stop plates, and are fixedly connected through bolts respectively. The vertical sleeve sleeves the upper end of the vertical stand bar, so that when the ship model heaves, the vertical stand bar moves up and down; and when the ship model heaves, vertical displacement is not limited in the vertical direction, so that too much forced limit of the ship model is not needed, and accuracy of the displacement data, measured in the wave, of the ship model is high.

Description

technical field [0001] The invention relates to the technical field of ship measurement, in particular to a ship seakeeping test device. Background technique [0002] It is well known that when a ship sails in waves, it will produce ship motion. The ship has six degrees of freedom of motion in the waves: pitch, roll, yaw, surge, sway and heave. When the ship sails in the waves head-on, To measure seakeeping the ship's motion in the longitudinal and vertical directions is measured. [0003] However, at present, there is no clear and standardized experimental device for testing the seakeeping test. Most of the seakeeping tests are carried out in the towing pool. When the trim angle is measured in waves, the ship model yaws, resulting in a deviation in the measurement angle, which affects the accuracy of the test results. Contents of the invention [0004] The purpose of the present invention is to provide a ship seakeeping test device, the device will not be restricted ver...
