Description
Technical field
The invention belongs to test mechanics field, it is related to a kind of static(al) examination of small size big load antenna house
Proved recipe method and its device.
Background technology
Slow test is a key problem in technology of radome design, GJB67 and each model antenna house
Slow test of the technical agreemet to antenna house proposes requirement.The load of each slow test at this stage
Lotus load mode, is mainly used loading woven belt to apply and draws load, applied using symbol type wooden unit and pressed
Load, and applied for the electronic warfare antenna house of small size big load using woven belt and symbol type wooden unit
Load, be easily caused antenna house local stress it is excessive there are the phenomenons such as antenna house local delamination, examination
Test condition excessively harsh.Meanwhile, the radome of small size also applies woven belt and wooden unit without space
Structure.
The GJB150 such as band temperature, humidity, mould, salt fog are carried out using woven belt and symbol type wooden unit is loaded
It is required that environmental condition slow test when, it is necessary to loading space it is very big, and be unfavorable for environment examination
The loading sealing of tryoff.
The content of the invention
The technical problem to be solved in the present invention is:A kind of static(al) of small size big load antenna house is provided
Test method and its device, it is convenient to carry out to ensure the aerodynamic loading of more real artificial antenna cover
Whole cap environment experiment under environmental condition with the GJB150 such as temperature, humidity, mould, salt fog requirements.
In order to solve the above technical problems, technical scheme is as follows:
A kind of small size big load antenna house static test device, the experimental rig adds including air bag
Carry chamber, air bag, loading pipeline, pressure gauge, pressure regulator valve, threeway block, pressure control machine and air compressor machine;
One loading surface of loading by air bag chamber and test antenna cover surrounds a closed cavity jointly;Air bag,
Loading pipeline, pressure gauge, pressure regulator valve, threeway block, pressure control machine and air compressor machine are linked in sequence.
Using the slow test method of above-mentioned experimental rig, comprise the steps of:
Step one, loading by air bag chamber is processed;
Step 2, handles loading by air bag chamber, it is ensured that LOADED CAVITY surface is smooth, and in inner cavity surface
Felt is placed to be protected;
Step 3, loading by air bag chamber is installed on by air bag;
Step 4, connection air bag and loading pipeline, utilize pressure control machine, air compressor machine, pressure regulator valve and pressure
The control pressurization of power table;
Step 5, joint test loading apparatus realizes slow test with test measurement instrument.
Beneficial effects of the present invention:Using slow test method of the present invention and its device, day can be made
Irdome loading is uniform conservative, it is ensured that the security of slow test, and can apply ring by GJB150
Border condition, realizes the slow test with antenna house under the conditions of environment.

Below in conjunction with accompanying drawing, the present invention will be further described.
Step one, processed according to antenna house size and profile feature in loading by air bag chamber 3, LOADED CAVITY
The connection of aerobic capsule 1 and loading pipeline 4 is stayed to draw hole;
Step 2, the inner surface of loading by air bag chamber 3 is handled using file, removes loading cavity wall
Burr, wedge angle, it is ensured that LOADED CAVITY surface is smooth, and place suitable in the inner cavity surface of LOADED CAVITY
The felt of size and thickness is protected;
Step 3, loading by air bag chamber 3 is installed on by air bag 1, gentle using fluid sealant, attachment spacers
Capsule connects mouth matching nut pressure bladder, draws hole from the connection of LOADED CAVITY and draws air bag connection mouth;
Step 4, connection air bag 1 and loading pipeline 4, loading pipeline 4 and pressure are carried out with fluid sealant
Table 5, pressure regulator valve 6, threeway block 7, the connection of pressure control machine 8 and air compressor machine 9 are sealed, and utilize pressure control
Machine 8, air compressor machine 9, pressure regulator valve 6 and the control pressurization of pressure gauge 5;
Step 5, draws displacement measurement and strain measurement line, connection displacement transducer and strain measurement
Instrument, coordinates experiment loading apparatus and realizes slow test with test measurement instrument.
