The invention provides a kind of experimental rig for just having consolidated stiffened panel axial compression test for surrounding, stiffened panel is studied with this
Flexural property and ultimate strength problem under axial compressive force effect.
The present invention is to be achieved through the following technical solutions surrounding just to consolidate stiffened panel axial compression test.Stiffened panel top passes through
Fastening bolt is connected with fixture, and fixture top is connected by connecting bolt with loading structure.Stiffened panel bottom passes through fastening bolt
It is connected with fixture, fixture is connected by connecting bolt with bottom base.Stiffened panel or so stretches out a segment distance, is easy to it to press from both sides
It is held in the middle of two edge-on rails.Two edge-on rails are connected by connecting bolt with upper cover plate and bottom base.Bottom base is provided with bolt
Hole, can be connected with any test site pedestal, it is ensured that the stability of whole experimental rig.
The function of the present invention is the stiffened panel axial compression test under the conditions of realizing surrounding just admittedly, and it is mainly characterized by：On
Fixture connection loading structure is held to provide the firm border admittedly of stiffened panel test specimen upper end, upper end-fixture outer can vertically downward be slided along vertical rail
Move and do not rotate；Lower end fixture connection bottom base provides the firm border admittedly of stiffened panel test specimen lower end；Stiffened panel test specimen is left
Right both sides are held between the vertical rail in left and right, and that realizes stiffened panel test specimen the right and left just consolidates border, obtains the test data needed
And experimental phenomena, reach test objective.
