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] Such as figure 1 Shown, the pool ship model test of the present invention uses the connecting rod type horizontal plane motion mechanism, including the support frame 2,19 fixed with the pool ship model trailer 1, the mounting frame 9 and the two servo electric cylinders 18,8 used for fixing the front and rear 15, the beam 3 is flexibly connected with the push rod 10 and the connecting rod 16 through the rotary joint 17. The connecting rod installation hole 12 on the beam 3 is fixed with the front and rear connecting rods 4, the connecting rod 4 and the adjusting rod 5 automatically adjust the length of the front and rear connecting rods through the linear bearing, and the force measuring balance 7 is connected with the ship model 6 and the adjusting rod 5 to form a connecting rod type Horizontal plane motion ...

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 cylinder18, 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...
