Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As shown in Figure 1, being the platform body structure schematic diagram of one of one preferred embodiment of the utility model testing stand.Table top
21 are mounted on 24 top of rack by decoupling mechanism 22, and actuator 23 connects rack 24 and table top 21, form stage body 2, and fixed
On ground 5.Suspension cable 3 is installed on 21 periphery of table top, and suspension cable 3 is connect with multiple clump weights 4, is connected between each clump weight 4 with suspension cable 3
It connects.When stage body 2 is in zero-bit, i.e., horizontal equilibrium position when, table top 21 keeps horizontal, and both ends are in the clump weight of suspended state
4 quantity and gross mass are equal, realize balance.Test specimen 1 is mounted on table top 21.The quality and quantity of clump weight 4 can be according to need
It adjusts, is connected between the clump weight 4 and the table top 21 of top side also by suspension cable 3.The decoupling mechanism
22 are rotatablely connected with the table top 21 by a Cardon universal joint structure multiple degrees of freedom.By described between multiple clump weights 4
Suspension cable removably connects, and in order to meet different test specimens 1, the clump weight 4 of different quality can be replaced, to reach by disassembly
Effect is best.
It is the course of work schematic diagram of one of one preferred embodiment of the utility model testing stand refering to attached drawing 2.Stage body
When 2 work, under the action of actuator 23, by decoupling mechanism 22, table top 21 rotates: the I end decline of table top 21, II end
Rise.The center of gravity m of test specimen 1 deviates the center of stage body 2, and deviates to I end, and the active force for generating test specimen 1 is applied to table top 21
I end.I end of table top 21 makes the clump weight 4 for being in suspended state originally be changed into landing state one by one since position reduces.
II end makes the clump weight 4 for being in landing state originally be changed into suspended state one by one since position increases.At this point, II end is matched
The pulling force that pouring weight 4 generates is increasingly greater than the pulling force that the clump weight 4 at I end generates, and the active force phase generated with test specimen 1 to table top 21
It offsets, realizes autobalance.The cavity that there is the clump weight 4 disk to put the suspension cable 3.When clump weight 4 is in landing shape
When state, the suspension cable 3 between the clump weight 4 of two adjacent landing states is accommodated in the cavity of downside clump weight 4.
As shown in figure 3, being that one of one preferred embodiment of the utility model testing stand carries out the installation of System for Large-scale Specimen unbalance loading
Course of work schematic diagram.Actual tests work in, test specimen 1 on table top 21 in unbalance loading install, i.e. the center of gravity m of test specimen 1 with
The center of stage body 2 is not overlapped, close to II end position of table top 21.At this point, the quality of two sides clump weight 4 need to be adjusted, it is in I end
4 gross mass of clump weight of suspended state is greater than 4 gross mass of clump weight that II end is in suspended state, when realizing zero-bit, 1 He of test specimen
Table top 21 is in equilibrium state, such as attached drawing 3 (a).
When stage body 2 works, when the decline of I end, II end rise, the center of gravity m of test specimen 1 is from II end by the center of stage body 2 to I
End offset.The clump weight 4 that I end is in suspended state originally is changed into landing state one by one；II end is in landing state originally
Clump weight 4 is changed into suspended state one by one, such as attached drawing 3 (b).
When I end rises, II end declines, the center of gravity m of test specimen 1 is deviated to II end.I end is in the counterweight of landing state originally
Block 4 is changed into suspended state one by one；The clump weight 4 that II end is in suspended state originally is changed into landing state one by one, such as attached drawing 3
(c).Therefore, in whole work process, clump weight 4 is mutual to the active force and active force of the test specimen 1 to table top 21 of table top 21
It offsets, realizes the autobalance of System for Large-scale Specimen unbalance loading installation.
It can be according to 1 mass of test specimen and position of centre of gravity in table top surrounding setting multiple groups series connection clump weight 4 in the present embodiment.
The present embodiment is by being arranged in series clump weight 4 using suspension cable 3 in 21 surrounding of table top, according to 21 position of table top when test
Weight mass can be changed automatically, so that the active force that test specimen 1 generates when autobalance inclination and rolling test, actuator are smaller
Output can be achieved with the inclination rolling test of System for Large-scale Specimen, reduce energy consumption, pacify particularly suitable for System for Large-scale Specimen unbalance loading
The inclination rolling test of dress.
Embodiment described above is only the preferred embodiment lifted to absolutely prove the application, the protection model of the application
It encloses without being limited thereto.Those skilled in the art made equivalent substitute or transformation on the basis of the application, in the application
Protection scope within.The protection scope of the application is subject to claims.
