Description
Technical field
The present invention relates to the foldable structures with geometry roll-off characteristic, and in particular to has pre-folded and geometry roll-off characteristic
Geometry transition slab structure.
Background technique
Three Pu paper foldings are suggested from the beginning, subsequent since the characteristic of its space telescopic is applied to aerospace field
It is applied in many life productions, if patent name is " panel of energy fast folding and expansion ", patent publication No. is
CN105757438A.With going deep into for research, three Pu paper foldings are gradually applied in sandwich structure as sandwich layer is folded.Relative to
Traditional honeycomb, this kind of structure have unique advantage: (1) folding sandwich layer preparation process and easily realize, maintain raw material
Continued integrity, it can be achieved that large scale and automated production etc.；(2) it folds peculiar cavity structure inside sandwich layer and is very suitable to sky
The circulation of gas, condensate liquid；(3) it is the three-dimensional structure with 5 absolute construction sizes, passes through optimization geometric dimension and knot
Structure feature is, it can be achieved that be better than the mechanical property of honeycomb.But meanwhile three traditional Pu structures are repeated by identical unit
Superposition composition, overall structure keep uniform, can not preferably adapt to the situation of extraneous load complexity.In face of extraneous complex load,
Graded material and structure improve its mechanical performance by changing the modes such as microstructure and density, such as Yves Conde (Conde
Y.,Pollien A.,and Mortensen A.2006,“Functional grading of metal foam cores
for yield-limited lightweight sandwich beams”.ScriptaMaterialia,54(4),pp.539-
543) by changing density acquisition there is the foam metal of roll-off characteristic to be applied in sandwich structure, improves sandwich beams knot
The carrying yield limit of structure.Yu Zhang(Zhang Y.,and Ma L.,2009,"Optimization of ceramic
Strength using elastic gradients " .Acctamaterialia, 57 (9), pp.2721-2729) utilize gradual change
The bearing capacity of structural improvement ceramic, it is seen that roll-off characteristic is conducive to improve the bearing capacity of structure.Therefore by changing three Pus
Roll-off characteristic is introduced into three Pu structures by the geometry of structure, while improving load-carrying properties, can also make full use of gradual change
Mechanical performance so that it is preferably adapted to complicated extraneous load.
Summary of the invention
Purpose of the invention is to overcome the shortcomings in the prior art, using the concept of grading structure and paper folding, proposes
It is a kind of can be folded by flat sheet formed, geometric parameter is variable and the geometry transition slab structure with gradual change mechanical performance.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of geometry transition slab structure is spliced to form by least two modules along two mutually orthogonal directions, described two
A mutually orthogonal direction be respectively horizontally and vertically, transition slab structure can vertically, horizontal direction two
Direction infinitely extends superposition；The module is folded according to three Pu paper folding patterns, and the three Pus paper folding pattern is four complete
The mirror image of identical parallelogram splicing composition, the three Pus paper folding pattern there is one degree of freedom, it can be achieved that
It folds and is unfolded completely；Parameter changing module in the form of point column or branch realizes the geometry for keeping space folding exhibition characteristic
Transition slab structure, the parameter of the module include horizontal direction side length, vertical direction side length, angle and the module number of module.
Further, there are seven kinds of modes along the parameter for dividing column direction to change the module: respectively changing the level of module
Direction side length changes the angle of module, changes the vertical direction side length of module, changes simultaneously the horizontal direction side length and folder of module
Angle changes simultaneously the angle and vertical direction side length of module, changes simultaneously the vertical direction side length and horizontal direction side length of module,
Change simultaneously vertical direction side length, angle and the horizontal direction side length of module.
Further, along divide column direction to change the module number, it can be achieved that module number variation ratio be 1:n, n is
Integer greater than 1.
Further, change the parameter of the module along branch direction there are three types of modes: respectively change module is vertical
Direction side length changes the quantity of module, changes simultaneously the vertical direction side length and module number of module.
Further, change the module number along branch direction, it can be achieved that module number variation ratio be 1:n, n is
Integer greater than 1.
Further, the transition slab structure can be combined with each other by point column with gradual manner involved in branch, be formed
New transition slab structure.
Further, the transition slab structure is telescopic structure, and when running parameter is not related to module angle, gradual change is hardened
Structure can fold or expand into completely a plate.
Compared with prior art, the beneficial effects brought by the technical solution of the present invention are as follows:
(1) geometry design parameter of the geometry transition slab structure is abundant, can flexibly change structure according to different engineer applications
Design parameter.
(2) the structure initial state has one degree of freedom, it can be achieved that a degree of freely fold, when one limit of arrival
The point present apparatus can be realized self-locking, promote its bearing capacity rapidly, and the latching point can be set by the adjustment of geometric parameter.
(3) structure can change the mechanical performance that geometric parameter realizes gradual change type, such as variation rigidity by system, thus
Actual requirement of engineering can be better met.
(4) structure can be folded along scrimp by a flat sheet and be formed.The surface of total is applicable surface, whole knot
Structure can be shaped directly by one flat plate, this to process more convenient, greatly reduce production cost, and process
Accuracy also can be improved.
