Description
Technical field
This utility model belongs to compression-resistant structure field, and more particularly, to a kind of many planes pressure-resistance structure, this structure is being protected
While card compressive property, reduce changeover portion between the cylinder and spherical shell mechanical characteristic shadow to entirely many planes pole-shell structure
Ring.
Background technology
For operationally needing to bear the equipment of very big external pressure, such as airborne vehicle, submarine, bullet etc., its
Pole-shell structure has vital impact to its compressive property.For strengthening the critical external compressive resistance ability of shell mechanism, generally have two
The method of kind, a kind of is that existing structure is carried out thickening strengthening the architectural characteristic of itself, and another kind of method is that existing structure is entered
Row transformation, reaches the purpose of enhancing structure mechanical characteristic by structural advantage.For example, U.S. Utility Patent
Us005711244 discloses a kind of many planes pole-shell structure with stronger critical external compressive resistance ability, and the columnar part of this structure is
Plane plate is spatially spliced by some cycles folding, and afterbody is ball sealing header structure, and columnar part and ball sealing
Head is connected by changeover portion, forms the similar pole-shell structure of a sealing.On the basis of this many planes pole-shell structure, existing
The reinforcement structure of some other many planes pole-shell structure is also proposed in technology.
However, further investigations have shown that, because entirely many planes column structure uses plane plate spatially
Folding splicing, lead to column structure could must be attached with spherical shell cover using transition section structure.In the case, such as
Fruit is spliced using the changeover portion of circular arc, because transition section structure has the Curvature varying of complexity, so not only manufacturing
Technique sufficiently complex, but also very big error can be produced.On the other hand, the presence of transition section structure also result in overall many
The overall mechanical characteristic of plane pole-shell structure reduces, and anti-pressure ability declines under water.Correspondingly, this area is needed badly to many plane cylinder shell
Structure is made and further being improved, and overcomes the difficulty that changeover portion is manufactured, and it can be avoided that depositing due to changeover portion
And defect that many planes pole-shell structure overall performance of leading to declines, to meet the needs of its compressive property and the mode of production.
Utility model content
Disadvantages described above for prior art or Improvement requirement, this utility model provides a kind of many planes pressure-resistance structure,
Wherein by set-up mode respective to its key building block and its be mutually linked the aspects such as cooperation and be designed, mutually should be able to
