Collapse energy-absorption experiment is carried out to material and component, its energy absorption characteristics is obtained and collision conquassation dynamic characteristic seems very necessary.
Collapse energy-absorption is tested based on axial crushing test, and rectangular section sample application is more universal, according to sheet metal thickness
Difference, by sheet stamping forming or be bent into U-shaped, the flange of U-shaped sample and web spot welding obtained into hat thin walled beam structure.
Using the weight of interconvertible different quality, the weight that certain altitude has been risen to by unclamping freely is fallen, and hits base work
Sample on table top, by power and the measurement of displacement, obtain axial compressive force-conquassation distance, absorb energy-conquassation distance Curve,
Energy absorption characteristics and collision conquassation dynamic characteristic are evaluated by average crushing force, deformation pattern etc..
In process of the test, because sheet metal thickness is different, the height and width difference of hat thin walled beam test specimen square-section compared with
Greatly；Test specimen is vertically installed on crushing test machine, and one end is freely without constraint, and the other end is fixed on horizontal base by fixture；
Fixture should ensure that being smoothed out for axial conquassation, and six-freedom degree limitation should be carried out to sample, it is necessary to according to examination in fixing end
The suitable fixture of sample size selection.
At present, existing test fixture size fixation can not be adjusted, it is necessary to big according to the different of sheet metal thickness, square-section
Small difference is equipped with various sizes of fixture, causes the poor universality of fixture；And be fixed on horizontal base can not for whole fixture
Move freely, cause sample and centering of dropping hammer is poor；Cause sample in experiment that inconvenience and loss economically, Er Qieying are installed
The experiment deadline is rung, so as to influence engineering design progress.
The content of the invention
The purpose of this utility model is to provide a kind of collapse energy-absorption test fixture platform, solves existing equipment general

On be provided with bayonet socket；Fastening briquetting 5 is connected by fastening bolt 6 with fixed board 4；Fastening the position of briquetting 5 can cut according to rectangle
Face width is different and adjusts tight；Fasten and stay bolt 3 is housed on briquetting 5, upper and lower two pairs of stay bolts 3 connect with clam member 2 respectively
Connect.The length dimension of stay bolt 3, can be adjusted according to the height difference of square-section.
T-shaped slideway on pedestal 1 is 3, and is parallel to each other；
Bayonet socket on fixed board 4 is 4, and symmetrical, position is adjustable；
The base of fixed board 4 is T-shaped.
Clam member 2, stay bolt 3, fastening briquetting 5 and fastening bolt 6, which are referred to as fastening, accommodates part；Clam member 2 is two
Block, fastening briquetting 5, fastening bolt 6 and stay bolt 3 are four；
Clam member 2, stay bolt 3, fixed board 4, fastening briquetting 5 and fastening bolt 6 are referred to as holder part；
A kind of technical solution of collapse energy-absorption test fixture platform of the utility model is：Install test component it
Afterwards, according to the centering requirement dropped hammer between component, move fixed board 4 along T row slideways and adjust position relative to pedestal 1
Put.
The utility model has the advantage of：The problem of solving existing equipment poor universality.For different plates thickness, no
Same square-section width and height, can be met using a sleeve clamp and use needs；Meanwhile, can be with after test specimen is fixed
By adjusting relative position of the fixture in pedestal so that test specimen and drop hammer and meet the requirement of centering, test operation is improved
The reliability of convenience and test data, improves the efficiency of experiment and the precision of data.
