The motion mechanism comprises a mechanism frame 14, a straight bearing 8, a roller bearing 15, a ball screw 11 and a swaying servo motor 20, wherein the mechanism frame is connected with an auxiliary trailer 10; an encoder 17 and a swaying frame 9 are connected with the mechanism frame 14 through the straight bearing 8 and the roller bearing 15 to form a swaying component; a composite bearing 12, a worm gear 13, a circumferential guide rail 6, a yawing servo motor 18, an encoder 19 and a connecting plate 5 are connected with the swaying frame 9 through the worm gear 13 to form a yawing component; the distance between a front connecting rod and a rear connecting rod 3 can be adjusted by a positive and negative screw 4; the lengths of the connecting rods 3 can be adjusted by a trapezoidal lead screw 7; and the upper ends of the front connecting rod and the rear connecting rod 3 are connected with the connecting plate 5, while the lower parts are connected with a joint 1, a force balance 2 and a ship model 16. A linear motion guide rail consisting of the straight line bearing and the roller bearing is adopted in the swaying component, so the swaying component has the advantage of high stability, large amplitude, and high precision. A rotary mechanism consisting of the composite bearing, the circumferential guide rail, the worm gear and a worm is used as the yawing moving component, so that the yawing moving component has the advantages of stable rotation, wide range of rotation angle, large torque, high self-locking property and high accuracy. The distance between the front connecting rod and the rear connecting rod and the lengths of the connecting rods are adjusted by using the positive and negative screw and the trapezoidal lead screw, so the mechanism has the advantages of convenience, accuracy and suitability for ship models with various specifications.
Description
Technical field
The present invention relates to the dummy ship test, more specifically relate to a kind of mechanism of measuring boats and ships model sport performance.
Background technology
The towing tank test planar motion mechanism, these testing technique have been widely used in tests such as boats and ships, aircraft, robot at present by U.S.'s exploitation at the beginning of the fifties.Most vertical installation and the hydraulic-driven of adopting of existing boats and ships pond horizontal planar motion mechanism.The hydraulic-driven volume is big, complex structure, and the control difficulty, precision is low, and the sealing requirements height pollutes the pond easily during leakage of oil.Poor rigidity under large amplitude, high-frequency condition is easy to generate vibration, influences measuring accuracy.
For addressing the above problem, it is strong to the invention provides a kind of rigidity, and good stability is easy to operate, controls accurate, safe and reliable towing tank test platform type horizontal plane planar motion mechanism.
Summary of the invention
For addressing the above problem, the technical scheme that the present invention takes is:
A kind of platform type horizontal plane planar motion mechanism of the present invention, comprise and auxiliary trailer bonded assembly institutional framework, linear bearing, roller bearing, ball-screw, swaying servomotor, coder, the framework that traverses are connected to form the swaying parts by linear bearing and roller bearing and institutional framework.Combination bearing, worm and gear, circumference guide rail, head shake servomotor, coder, connecting panel and are connected to form first shake component by worm and gear and swaying framework.The positive and negative screw rod of pipe link distance before and after regulating is regulated the trapezoidal screw of pipe link length, and pipe link top, front and back links to each other with connecting panel, and the bottom links by force balance and ship model.Form platform type horizontal plane planar motion mechanism.
Compared with prior art, the invention has the advantages that:
1, adopt linear bearing, roller bearing and circumference guide rail, rigidity is strong, good stability, is not acted upon by temperature changes, and is easy to maintenance, survey precision is high;
2, distance adjustment adopts positive and negative screw rod between two pipe links of front and back, and is easy to operate, applicable to the ship model of various different sizes;
