Description
Technical field
The present invention relates to a kind of structural units, more particularly, to the structural unit with viscoelastic property.
Background technology
Now to realize the viscoelastic sexual function of structural unit, it is often designed to complicated mechanism or system, such as automobile
Suspension, to realize that the function of car damping damping is set, not only complicated, quality is larger, but also only vehicle body
Integrally-built adapter also takes up larger space to increase the integrally-built weight of vehicle body.Therefore, how to carry
Go out a kind of light weight, simple in structure and there is viscoelastic sexual function, it can the part carrying local stiffness of structure as a whole
Structural unit, the problem of becoming urgent need to resolve.
Invention content
The object of the present invention is to provide a kind of structural units simple in structure, light weight with viscoelastic sexual function.
Technical solution of the invention is：A kind of structural unit with viscoelastic sexual function, including structural unit ontology,
At least one adjacent interfaces are equipped in the structural unit ontology, the adjacent cells body of interface both sides is in the structural unit sheet
The constrained state in internal portion is different.
At least one interface is equipped in structural unit ontology, due to the two neighboring cell cube constrained state of interface both sides
Difference, under by outer force effect, opposite sliding and friction occur for the deformation of two cell cubes, to generate damping,
So that structural unit ontology is realized viscoelastic sexual function, can structure as a whole a part, carry local stiffness.It is formed in this way
Structural unit light weight is formed viscoelastic simple in structure.
The interface both sides adjacent cells body be respectively both ends not with the structural unit ontology in connect pass through
The non-through plate being connect in logical plate and one end freedom and the other end and the structural unit ontology.Run-through board can be directly sharp
Realize that the design of non-through plate can further mitigate the matter of structural unit ontology with the frame part of structural unit ontology
Amount.
Adjacent cells body in the interface both sides be respectively two one end freedom being staggered and the other end with it is described
The non-through plate connected in structural unit ontology.Non-through plate is staggered, and structural unit body interior can be made full use of empty
Between, on the basis of having viscoelastic sexual function, the total quality of unit can also be further reduced.
Damping material is filled in the interface.The frictional damping for further increasing interface improves the viscous of cell body
Elasticity.
The run-through board and non-through plate are respectively surface plate or curved slab.Increase structural unit ontology structure as a whole
Adaptability.
It is an advantage of the invention that：It is simple in structure but have viscoelastic sexual function, and can as a whole structure a part come
The structural unit of local stiffness is carried, is overall structure loss of weight, saves space.
