Description
Technical field
The equipment that the utility model is related to a kind of analog simulation and posture adjustment, realizes that what is rotated turns in particular with arc orbit
Platform.
Background technology
Turntable has played more next as a kind of analog simulation and the equipment of posture adjustment in fields such as modern military, industry, space flight
More important effect.In the world, because inertial guidance techniques are subject to generally weighing for developed country and developing country in the world
Depending on, and turntable is the important non-standard equipment for testing inertance element and HWIL simulation, the quality of its performance directly affect emulation and
The reliability and confidence level of test, thus the state such as the U.S., Russia, Britain, France, Switzerland, China, India all put into it is substantial amounts of
Manpower and materials are engaged in turntable development.In the decades being born so far from First turntable in 1945, to the important component of turntable such as
Bearing, drive motor, detecting element have all carried out the improvement of system, have developed the air bearing and hydraulic axis for being exclusively used in turntable
Hold, big speed ratio, high-precision hydraulic motor and high-resolution detecting element.China also have developed the essence of many different purposes
Close servo turntable, from home products under same structural strength home products do it is heavier, load is smaller, and this is to small-sized
Change, mobility brings very big difficulty.
The classification of turntable has various methods, and the free degree of the angular movement reappeared by turntable table top is distinguished, and can be divided into single shaft
Turntable, double axle table, three-axle table and five-axis flight table, wherein three-axle table are most widely used.Three-axle table is with control theory, phase
It is instrument using computer and special physical equipment based on like theoretical, systems technology and information technology, is inertial navigation and system
Guiding systems l-G simulation test provides the key equipment of platform.
At present, most three-axle table bulk mechanical system is made up of three frameworks and support two large divisions, predominantly bears
Carry and reference for installation is provided and rolling, pitching, the shafting gyration of course three is realized, so it can really be simulated on the ground
The various flight attitudes of aircraft, guided missile etc., test its element and system, it is to avoid carries out the actual loading test of costliness,
Its process can be predicted and be repeated by simulation, be that solid foundation has been established in development in kind.With regard to its mechanical structure
From the point of view of it is most of use real axis serial configureds, each shafting mixes independent driver element, so as to realize the space of targeted loads
Attitude regulation.Such as China Patent No. is 201320712433.0, and patent name is a kind of three-axle table, it discloses a kind of three

Posture changing.China Patent No. is 201220751996.6 for another example, and patent name is a kind of electronic three-axle table, it discloses
A kind of free adjustment angle, positioning precision electronic three-axle table high, including base, are fixed on the servomotor on base, institute
State base to be connected with swivel mount by conducting slip ring, the swivel mount is provided with turntable module.
The maximum problem of this kind of turntable is to load the centre of gyration of deviation of gravity center gyroaxis farther out, when load quality is smaller
This problem is not also to protrude very much, when load quality it is larger especially load center of gravity to turntable installation daylight opening DLO from it is larger when this
Problem is just especially prominent, and this is that stiffness and strength requirement is also improved, turntable because heavily loaded bias increases moment of torsion required for turntable
Quality also just increases therewith.The dynamic property that counterweight can also be added sometimes for heavy load turntable to improve with improve turntable, such as
, load trim, power naturally can be small, but can also increase turntable quality in itself because counterweight is heavier in itself for fruit addition counterweight,
If not trim, quality relative trim naturally can be small, but power can increase, and dynamic characteristic reduction, total capacity dies down.Should at some
With in occasion such as warship, there can be strict requirements to the quality of turntable and power.These all hinder the development of turntable, limit
The application scenario of turntable, influences the popularization of turntable.
