The I-shaped steel base is mounted on testing stand, and I-shaped steel base is by top flange steel plate, web and lower flange steel plate
It is composed, there are prefabricated slot on the top flange steel plate and web,
The fixture group is required according to test specimen is fixed, using a kind of or multiple groups, fixture group include top limit clamp with
Lower support fixture, the fixture group are fixed among the slot reserved on I-steel, and backing plate is carried and is fixed on by fixture group
Test specimen support device is formed on pedestal, backing plate is clamping plank, plastic plate, cystosepiment or glass plate, is placed with examination on backing plate
Block.
Preferably, the I-shaped steel base includes common I-steel, lightweight I-beam and h section steel, steel plate
Connection type includes welding, rivets and be bolted.
Preferably, high strength construction steel can be used in the fixture group.
Preferably, the thickness of the backing plate can be 0.1mm~10mm, material and thickness are carried out according to test specimen weight
Selection.
The utility model can apply to the vertical supporting of the horizontal impact test of high speed impact, low speed.
The utility model has the advantages that the Hopkinson bar test of the utility model not only can be to test specimen with multi-functional test specimen support device
Vertical supporting is provided, and small with test specimen contact surface, backing plate can be convenient replacement after destroying in test.Both carrying test specimen had been solved
The problem of vertical carrying, will not have an impact to the precision of test with observability.This utility model, which meets a variety of tests, to be needed
It asks, there is wide application prospect.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figs. 1-7: the Hopkinson bar test is with multi-functional test specimen support device by I-shaped steel base 1, fixture
Group 2 is composed with backing plate 3.
The I-shaped steel base 1 is formed using the steel plate combination with reserved slot 10, and intensity with higher is to carry
The weight of test specimen.I-shaped steel base 1 is connected using screw with testing stand 4.I-shaped steel base 1 by top flange steel plate 5, web with
Lower flange steel plate 6 is composed.
The fixture group 2, which is fixed on I-shaped steel base 1 using screw, to be reserved in slot 10, can be mobile in reserved slot 10
To be suitable for and various sizes of backing plate.The fixture group 2 includes top limit clamp 8,9 two kinds of lower support fixture.
The effect of the top limit clamp 8 is the stability limited in backing plate horizontal direction, to guarantee the vertical of backing plate.
The effect of lower support fixture 9 is the test specimen load supported by transmitting on backing plate 3.
The backing plate 3 is fixed on I-shaped steel base 1 by fixture group 2, is in contact with test specimen, by the Adjusting Shape of test specimen
Backing plate shape is with gradually few area contacted with test specimen.Determine the material and thickness of backing plate 3, by the load of test specimen to the same of carrying
When meet test requirements document.
A kind of manufacturing method of separate type Hopkinson dry test test specimen support device, including the following steps:
1) steel plate is slotted, and steel plate is combined using welding, formed I-shaped steel base, using screw by its
It is fixed on testing bed, testing stand.
2) fixture group is produced using high-strength steel, since Hopkinson bar test test specimen only needs single-point support, only
It needs to make one group of fixture group, and fixture group is fixed on I-shaped steel base using screw rod.
3) since test specimen is in the form of annular discs, select spill groove as the shape of backing plate.Due to being not required in impact test
It supports, therefore selects the 3mm veneer(ed) wood for being easy to destroy as raw material, produce backing plate.
Alignment jig group fixes backing plate, and test specimen is supported on backing plate, and test can start.
It is described in detail above in conjunction with embodiment of the attached drawing to the utility model patent, but the utility model patent is not
It is confined to described embodiment.For those of ordinary skill in the art, in the principle of the utility model patent and skill
In the range of art thought, a variety of variations, modification, replacement and deformation are carried out to these embodiments and still fall within the utility model patent
Protection scope in.
