Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1, being the platform body structure of one of a preferred embodiment of the present invention self-balancing inclination Swaying Test Platform
Schematic diagram.Table top 21 is mounted on 24 top of rack by decoupling mechanism 22, and actuator 23 connects rack 24 and table top 21, forms platform
Body 2, and be fixed on ground 5.Suspension cable 3 is installed on 21 periphery of table top, and suspension cable 3 connect with multiple clump weights 4, each clump weight 4 it
Between with suspension cable 3 connect.When stage body 2 is in zero-bit, i.e., horizontal equilibrium position when, table top 21 keeps horizontal, and both ends are in suspention
4 quantity of clump weight and gross mass of state are equal, realize balance.Test specimen 1 is mounted on table top 21.The quantity and matter of clump weight 4
Amount can adjust as needed, be connected between the clump weight 4 and the table top 21 of top side also by suspension cable 3.Institute
The decoupling mechanism 22 and the table top 21 stated are rotatablely connected by a Cardon universal joint structure multiple degrees of freedom.Multiple clump weights 4 it
Between removably connected by the suspension cable, in order to meet different test specimens 1, matching for different quality can be replaced by disassembly
Pouring weight 4, it is best to reach effect.
It is the course of work of one of a preferred embodiment of the present invention self-balancing inclination Swaying Test Platform refering to attached drawing 2
Schematic diagram.When stage body 2 works, under the action of actuator 23, by decoupling mechanism 22, table top 21 rotates: the I of table top 21
End decline, 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
It is added to I end of table top 21.I end of table top 21 is changed into the clump weight 4 for being in suspended state originally one by one since position reduces
Landing state.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,
The pulling force that the clump weight 4 at II end generates is increasingly greater than the pulling force that the clump weight 4 at I end generates, and table top 21 is generated with test specimen 1
Active force offsets, and realizes autobalance.The cavity that there is the clump weight 4 disk to put the suspension cable 3.At clump weight 4
When the state of landing, the suspension cable 3 between the clump weight 4 of two adjacent landing states is accommodated in the cavity of downside clump weight 4
It is interior.
As shown in figure 3, being that one of a preferred embodiment of the present invention self-balancing inclination Swaying Test Platform carries out large-scale examination
The course of work schematic diagram of part unbalance loading installation.In actual tests work, test specimen 1 is installed on table top 21 in unbalance loading, i.e. test specimen 1
Center of gravity m be not overlapped with the center of stage body 2, close to table top 21 II end position.At this point, the quality of two sides clump weight 4 need to be adjusted,
4 gross mass of clump weight for making I end be in suspended state is greater than 4 gross mass of clump weight that II end is in suspended state, realizes zero-bit
When, test specimen 1 and table top 21 are 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 to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.Those skilled in the art's made equivalent substitute or transformation on the basis of the present invention, in the present invention
Protection scope within.Protection scope of the present invention is subject to claims.
