Background technique
With the rapid development of Chinese society economy, more and more people select aircraft for the vehicles when going on a journey, and take
Comfortableness problem when aircraft is also increasingly taken seriously.Aircraft seat be on aircraft one it is important, directly and driver and passenger
Associated component, the vibration that aircraft is generated when taking off, landing, and generated in flight course jolt be easy so that multiplying
Seat personnel generate sense of discomfort, increase the physical fatigue of passenger.The skeleton buffering energy-absorbing effect of conventional airplane seat is not significant,
Damping effect is undesirable, cannot fully meet the demand of driver and passenger.The shock-absorbing function for optimizing aircraft seat skeleton, can not only
Increase the comfort of passenger, moreover it is possible to improve the working environment of pilot, mitigate the long-term irreversible physiological effect to pilot.
Summary of the invention
The present invention provides a kind of bionical damping aircraft seat skeleton, and its object is to improve the comfortable of existing aircraft seat
Degree provides a kind of light material, good damping effect, the strength of materials high comfortable damping aircraft seat.The present invention with antidetonation drop resistant,
The significant shaddock pericarp of cushion energy absorbing property and the beetle elytrum of good mechanical performance are bionical prototype, by micro- to beetle elytrum
Structural analysis couples shaddock pericarp and beetle elytrum material structure in conjunction with the observation of shaddock pericarp structure and the analysis of performance,
Optimization design goes out the high comfortable damping aircraft seat skeleton of light material, good damping effect, the strength of materials.
The pericarp of shaddock has special structure, and 70% is all dietary fiber in middle Pericarp Content, the short texture of middle pericarp
It is similar spongy, there is a large amount of gap between cell and cell, density gradually decreases from outside to inside, between cell and cell
There is a large amount of pectin to play adhesion and fixation, and this special construction of shaddock pericarp has great antidetonation and resistance to compression
Effect, simultaneous buffering energy absorption characteristics are extremely significant, shaddock can be made to fall from tree without breaking；The elytrum of beetle is a kind of compound
The structure of stratiform, and this structure is made of tens of layers of chitin fiber layer, they are spread in the different mode such as parallel, spiral
If this structure is light, intensity is high, wear-resistant, while also have excellent toughness, can protect beetle body and film wing not by
To extraneous injury.Therefore, the structure of shaddock pericarp and the coupling of beetle elytrum, can effectively decay high-frequency vibration.
The present invention includes left plate, right side plate, the first backrest frames, the second backrest frames, third backrest frames, support
Beam, supporting beam fixing seat, seat cushion framework, left plate, right side plate, the first backrest frames, the second backrest frames, third lean on spine
Frame, supporting beam, supporting beam fixing seat and seat cushion framework are coupled to form by hole configurations and straticulate structure, the hole
Hole structure is the aluminium alloy structure with hole of imitative shaddock pericarp, and hole configurations A using aluminium alloy as base material, contain by inside
A large amount of holes, hole configurations are made of three-decker, and the size of hole diameter is gradually reduced from inside to outside；Straticulate structure
It is the biomimetic features of imitative beetle elytrum, is laid in parallel by tens of layers of composite material, every a layer thickness is identical.
Hole configurations includes endothecium structure, interlayer structure, layer structure, and endothecium structure has the first hole, middle layer
Structure has the second hole, and layer structure has third hole；Straticulate structure is combined by tens of layers of single layer.
In described hole structure endothecium structure with a thickness of L1, interlayer structure with a thickness of L2, the thickness of layer structure
For L3, straticulate structure with a thickness of L4, wherein L1:L2:L3:L4=2:1:1:2.
The diameter of first hole is d1, and the diameter of the second hole is d2, and the diameter of third hole is d3, complex layered
The single layer of structure with a thickness of d4, wherein d1:d2:d3:d4=3:2:1:1.
Beneficial effects of the present invention:
Material of the present invention is light, and good damping effect, cushion energy absorbing property is significant, and structure is simple, can effectively reduce due to vibration
It is uncomfortable to passenger's bring, the comfort of passenger is improved, the working environment of pilot can also be improved.
