Abstract
The present invention is to provide a kind of aluminium ice solid propellant compressive property proving installation.Comprise pedestal (1), medicine groove (3), bearing rod (5) and stop (6), medicine groove (3) is placed in pedestal (1), stop (6) is arranged on pedestal (1) top, and bearing rod (5) is enclosed within stop (6) and bearing rod (5) acts on the surface of aluminium ice solid propellant test block (4) in medicine groove (3).During use, device of the present invention is fitted in Material Testing Machine, by mechanism, the pressure of Material Testing Machine is delivered to the surface of propellant test block, test its compressive property, solid propellant field tests can be applied to.
Description
Technical field
What the present invention relates to is a kind of compressive property proving installation of material, specifically a kind of aluminium ice solid propellant compressive property proving installation.
Background technology
At present, aluminium ice solid propellant has the advantages such as calorific value is high, smokeless due to it, becomes a kind of emerging propellant got most of the attention.Aluminium ice solid propellant is in the process of work, and be in the high pressure conditions in firing chamber, if aluminium ice solid propellant can resist the effect of high pressure load, then engine can normally work always.If aluminium ice solid propellant can not resist the high pressure load effect in firing chamber, then can there is the situations such as powder column fracture, fragmentation in aluminium ice solid propellant, and propellant combustion face increases rapidly, and combustion chamber pressure increases sharply,, also easily there is the danger such as blast in not only engine cisco unity malfunction.Therefore, it is very necessary for testing the compressive property of aluminium ice solid propellant before practical application.
Disclose the device that a kind of ignition performance for propellant carries out testing in patent document US2010294023, its compressible device is a sealed combustion chamber: disclose a kind of device for simulating propellant charge operating load within the engine in patent document US4523475.Its technical scheme is, utilizes a volume can temperature variant rubber device, by regulating the temperature of rubber device, making it expand or shrinking, and provides stretching strain or compressive strain by the expansion of rubber device and contraction to propellant test specimen.
Summary of the invention
The object of the present invention is to provide the aluminium ice solid propellant compressive property proving installation that a kind of structure is simple, processing ease, experiment effect are good.
The object of the present invention is achieved like this:
Comprise pedestal 1, medicine groove 3, bearing rod 5 and stop 6, medicine groove 3 is placed in pedestal 1, and stop 6 is arranged on above pedestal 1, and bearing rod 5 is enclosed within stop 6 and bearing rod 5 acts on the surface of the aluminium ice solid propellant test block 4 in medicine groove 3.
The present invention can also comprise:
1, cooling line 2 is had in pedestal 1.
2, the bottom of described medicine groove 3 and surrounding adopt unlike material to make, and medicine trench bottom material is measuring body rigid material, and side material is very easily by the material compressed.
The present invention adopts the method for temperature control and pressure transmission among a small circle to realize the test of aluminium ice solid propellant compressive property.Cooled by the environment of cooling line to whole device inside, ensure that the test block of aluminium ice solid propellant is not melted.Transmitted the pressure of Material Testing Machine by bearing rod, carry out the test of aluminium ice solid propellant compressive property.
Technical characteristics of the present invention is embodied in: be provided with cooling line in base interior, by cooling medium in cooling line inner loop, makes whole device be in low-temperature condition.Medicine trench bottom and surrounding adopt unlike material to make, and bottom adopts compression-resistant material, such as stainless steel, the titanium alloy etc. that rigidity is larger, and surrounding adopts very easily by material, the such as polyfoam etc. that compress.The movement of stop restriction bearing rod, ensures that bearing rod moves up and down, laterally offset does not occur.
The invention has the beneficial effects as follows: cooling line cools pedestal, the test block of aluminium ice solid propellant is in low-temperature condition, can not melt in process of the test; Medicine groove surrounding adopts the extremely squeezable materials such as polyfoam, the test block of aluminium ice solid propellant is similar to and is in Uniaxial Compression state; Stop ensures that bearing rod only moves up and down, and improves the accuracy of test.
During use, this device is fitted in Material Testing Machine, by mechanism, the pressure of Material Testing Machine is delivered to the surface of propellant test block, tests its compressive property, can be applied to solid propellant field tests.
Accompanying drawing explanation
Fig. 1 is this aluminium ice solid propellant compressive property proving installation structural drawing.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
Composition graphs 1, aluminium ice solid propellant compressive property proving installation of the present invention comprises pedestal 1, cooling line 2, medicine groove 3, bearing rod 5 and stop 6.Before test, by cooling medium in cooling line 2, ensure that pedestal 2 and other each several part are all in low-temperature condition.The raw material such as aluminium powder and water, after mixing, directly loads in medicine groove 3 and makes aluminium ice solid propellant test block 4.During test, open stop 6, take out bearing rod 5, medicine groove 3 is put into pedestal 1, build stop 6 and by bearing rod 5 embedding device.Whole device is put into Material Testing Machine, and the pressure of Material Testing Machine is delivered to the surface of aluminium ice solid propellant test block 4 by bearing rod 5, can test out the compressive property of aluminium ice solid propellant.
