Abstract
The invention provides a carbon fiber antenna radiation beam and a manufacturing method of the carbon fiber antenna radiation beam. Carbon fiber circular tubes replace traditional structural steel to form a beam frame, and butt joint positions of the carbon fiber circular tubes are connected through steel connectors in a glued mode. Compared with an existing manufacturing technology, the manufacturing method of the carbon fiber antenna radiation beam has the advantages that a traditional antenna radiation beam steel structure is changed, carbon fiber materials are used as main materials, manufacturing is conducted through the gluing technology, the weight of the radiation beam is greatly lowered, strength is large, rigidity is good, the process is simple, and the defects of a traditional antenna radiation beam are overcome.
Description
Technical field
The radiation beam technical field that the present invention relates to radar antenna, is specially a kind of carbon fiber aerial radiation beam and manufacture method thereof.
Background technology
Aerial radiation beam is the main support parts of antenna reflective face.Large aperture antenna reflecting surface be mainly used in large-scale precision instrumentation radar, survey of deep space and communicate by letter, large-scale radio astronomical telescope antenna structure subsystem, Main Function is reflection space electromagnetic wave.
At present, traditional aerial radiation beam mainly adopts the shaped steel such as T-steel, angle steel, steel pipe to be welded, and is a kind of girder construction.In whole antenna system, between antenna interarea and backrest, be designed with adjustment link, antenna interarea precision does not propose high-precision requirement to backrest system, and as the critical piece of backrest system, the accuracy of manufacture of aerial radiation beam requires also not high.So radiation beam generally adopts on jig line to amplify sample, each part by line place consolidate and determine after weld again, postwelding also need not carry out machine work uses.But because it is full steel structure, monomer weight is larger, is assembled in after antenna reflector, increased the weight of antenna reflector, counterweight, tie down whole antenna system, be also unfavorable for it to carry out conveniently driving accurately.And, under the installation environment of some extreme limit handling ability, the overall weight of antenna reflector need to be reduced, under the prerequisite of its structural rigidity of assurance, alleviate radiation beam weight and just become a kind of active demand.
Summary of the invention
The technical problem solving
The problem existing for solving prior art, the present invention proposes a kind of carbon fiber aerial radiation beam and manufacture method thereof, has solved the shortcomings such as existing aerial radiation beam weight is large, the accuracy of manufacture is low.
Technical scheme
Technical scheme of the present invention is:
Described a kind of carbon fiber aerial radiation beam, it is characterized in that: the roof beam structure of described aerial radiation beam adopts carbon fiber pipe, the joint of roof beam structure adopts steel joint, on steel joint, for the linkage section external diameter being connected with carbon fiber pipe, equal carbon fiber round tube inside diameter, steel joint is fixedly connected with by gluing with carbon fiber pipe; On steel joint, be welded with the adpting flange fixing with assembling mould.
The manufacture method of described a kind of carbon fiber aerial radiation beam, is characterized in that: adopt following steps:
Step 1: according to the design drawing of aerial radiation beam, the assembling mould of aerial radiation beam is adjusted on track or jig, and fixed with pressing plate;
Step 2: from one end of assembling mould, first fixing steel joint on assembling mould, then on the contact-making surface of carbon fiber pipe and steel joint, smear glue, according to the locations of structures of aerial radiation beam design drawing, carbon fiber pipe and steel joint is gluing fixing; Repeat this step, until complete cementing assembling from assembling mould end to end, carry out timeliness and solidify; Steel joint is departed from from assembling mould, obtain carbon fiber aerial radiation beam.
Beneficial effect
The difference of this carbon fiber aerial radiation beam manufacturing technology and existing manufacturing technology is, it has changed traditional antenna radiation beam steel structure, adopt carbon fibre material as main material, and the technology sticking with glue is manufactured, greatly alleviate radiation beam weight, intensity is large, good rigidly, and technique is simple, many deficiencies of traditional antenna radiation beam have been overcome.
