Abstract

The invention belongs to test mechanics field, is related to a kind of slow test method of small size big load antenna house and its device.Slow test method of the present invention, comprises the steps of:Step one, processing loading by air bag chamber;Step 2, processes loading by air bag chamber, it is ensured that LOADED CAVITY smooth surface is smooth, and is protected in inner cavity surface placement felt;Air bag is installed on loading by air bag chamber by step 2;Step 3, connection air bag and loading pipeline, using the control pressurization of pressure control machine, air compressor machine, pressure regulator valve and pressure gauge;Step 4, joint test loading apparatus realize slow test with test measurement instrument.Using slow test method of the present invention and its device, antenna house loading can be made uniform conservative, it is ensured that the safety of slow test, and environmental condition can be applied by GJB150, realize the slow test with antenna house under the conditions of environment.

Description

The slow test method and its device of a kind of small size big load antenna house
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.
Brief description of the drawings
Figure one is that slow test method of the present invention and its device use schematic diagram;
Wherein, 1- air bags, 2- antenna houses surface, 3- loading by air bag chamber, 4- loadings pipeline, 5- pressure Table, 6- pressure regulator valves, 7- threeways block, 8- pressure controls machine, 9- air compressor machines.
Embodiment
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.
