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 Ship model test, more specifically relate to a kind of mechanism of measuring boats and ships model sport performance.
Background technology
Towing tank test planar motion mechanism, these testing technique are developed by the U.S. beginning of the fifties, and oneself is widely used in the tests such as boats and ships, aircraft, robot at present.Most at right angle setting and the hydraulic-driven of adopting of existing boats and ships pond horizontal planar motion mechanism.Hydraulic-driven volume is large, and complex structure is controlled difficulty, and precision is low, and sealing requirements is high, easily pollutes pond during leakage of oil.Poor rigidity under large amplitude, high-frequency condition, easily produces vibration, affects measuring accuracy.
For addressing the above problem, the invention provides a kind of rigidity strong, good stability, easy to operate, control 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 the institutional framework being connected with auxiliary trailer, linear bearing, roller bearing, ball-screw, swaying servomotor, coder, swaying framework is connected to form 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, the trapezoidal screw of adjusting pipe link length, pipe link top, front and back is connected with connecting panel, and bottom is connected by force balance and ship model, forms 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, easy to maintenance, survey precision is high;
2, between two pipe links of front and back, distance adjustment adopts positive and negative screw rod, easy to operate, applicable to the ship model of various different sizes;
3, front and back two pipe link length adjustment adopt trapezoidal screw, and precision is high, applicable to the different draft of various ship models;
Accompanying drawing explanation
