Embodiment Construction

[0013] The link-type planar motion mechanism of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0014] like figure 1 and figure 2 Shown, the pool ship model test of the present invention uses the link-type horizontal plane motion mechanism, including the first support frame 2 and the second support frame 19 fixed with the pool ship model trailer 1, and two servo electric cylinders (the first one) before and after the fixation The electric cylinder 8 and the second servo electric cylinder 18) are used for the first mounting frame 9 and the second mounting frame 15, the push rod 10 of the first electric cylinder of the crossbeam 3 is movably connected with the crossbeam 3 through the first rotary joint 11, and the second electric The push rod 20 of the cylinder and the connecting rod 16 are movably connected with the beam 3 through the second rotary joint 17 . The connecting rod installation hole 12 on the bea...

Abstract

The invention provides a linkage type horizontal planar motion mechanism, which comprises bearer frames (2) and (19), a installation rack (9), a front back servo electric cylinder (8), a rear servo electric cylinder(18), a rotating joint (17), a connecting rod (16), a beam (3), a pushing rod (11) and a force balance (7), wherein a tank test trailer 1 is connected with the support frames (2) and (19); the installation rack (9) is used for fixing the front and rear servo electric cylinders (8) and (18); the beam (3) is moveably connected with the pushing rod (11) and a connecting rod (16) through the rotating joint (17); an installation hole (12) on the beam (3) is fixed with front and rear connecting rods (4); and the force balance (7) is connected with a ship model (6) and an adjusting rod (5). The formed linkage type horizontal planar motion mechanism can realize the swaying or yawing oscillation of the ship model through the stretching of the pushing rods of two servo electric cylinders and a sample feedback and control system of a position sensor in each servo electric cylinder; and the control system is driven by the servo electric cylinder, an in-built encoder samples and feeds back, and a programmable logic controller (PLC) is used for controlling, thus the invention has convenient controlling, rapid speed, high measurement accuracy, simple structure, convenient maintaining and long service life.

Description

technical field [0001] The invention relates to a ship model test, and more particularly relates to a mechanism for measuring the motion performance of a ship model. Background technique [0002] Plane motion mechanism for tank ship model test, this test technology was developed by the United States in the early 1950s, and has been widely used in tests of ships, aircraft, robots, etc. Existing ship tank planar motion mechanisms have small swaying amplitude, and most of them adopt hydraulic drive, which has large volume, complex structure, difficult control, low precision, high sealing requirements, and easy to pollute the pool when oil leaks. At present, the planar motion mechanism driven by connecting rod hydraulic pressure has only been applied in the fluid power laboratory. [0003] In order to solve the above problems, the present invention provides a link-type horizontal plane motion mechanism suitable for tank ship model tests with simple structure, convenient operati...
