Detailed description of the invention
Fig. 1 is general structure schematic diagram.
Fig. 2 is gradually cellular type shock resistance structure schematic diagram.
Fig. 3 is the structural schematic diagram of sandwich plate.
Specific embodiment
Below by attached drawing, the present invention is described in detail.
As shown in Figure 1, gradually cellular type bulkhead structure provided by the invention includes two parallel sandwich plates 1, described two
Gradually cellular type shock resistance structure 2 is equipped between sandwich plate 1.
As shown in Fig. 2, the gradually cellular type shock resistance structure 2 includes four uniformly distributed identical gradually cellular type structures, it is described
Gradually cellular type structure include slab 2-1, the slab 2-1 is gradually increased from top to bottom, the slab 2-1 be equipped with 3 by
Top to bottm is connect below the circular opening 2-2, the slab 2-1 that diameter changes from small to big with small panel 2-3.
The slab 2-1 and small panel 2-3 in each gradually cellular type structure are welded to connect.
Each gradually cellular type structure further includes raised 2-4, and the top of slab 2-1 is arranged in the protrusion, described
Raised 2-4 top it is parallel with sandwich plate 1, connected above the raised 2-4 with sandwich plate 1.
Raised 2-4 and the substrate being gradually increased below are conducive to increase the contact area with sandwich plate, when reduction is hit
Stress.
For better effect, slab 2-1 and protrusion 2-4 in each gradually cellular type structure are an entirety.
Small panel 2-4 and slab 2-1 uses yield strength for the 50CrNi5MoV martensite steel of 1350MP.The geneva
Body steel has good plasticity and high temperature resistant, ensures enough structural strengths and high temperature resistance.
As shown in figure 3, each sandwich plate 1 includes two parallel skin panels, the first skin panel 1-1 and second is covered
Be provided with battenboard 1-3 between dermatotome 1-2, the first skin panel 1-1, the second skin panel 1-2 and the gap battenboard 1-3 it
Between be filled with filler 1-4.
The first skin panel 1-1 and the second skin panel 1-2 upper outer surface is coated with insulating layer.The insulating layer is resistance to
High-temperature insulation heat-barrier material is made using ceramic fibre as primary raw material of wet therapy forming process.Advantage is: having resistance to height
The performances such as warm, resistant to chemical etching, heat shock resistance, low thermal conductivity, high electric insulation intensity and high elastic modulus.Its feature is no stone
Cotton, fiber are long, slag ball is few, bulk density is small, intensity is big, elasticity is good, convenient for constructing operations such as punching, windings.Suitable under high temperature
Heat-insulated, heat preservation, sealing, electrical isolation, sound-absorbing, filtering etc., are a kind of advanced lightweight refractory materials.
The filler 1-4 is foamed aluminium, and foamed aluminium has the physical properties such as good sound insulation, energy-absorbing, lower thermal conductivity, with
And when bending deformation occurs for skin panel, generates compared with large plastometric set dissipation energy, enhance the anti-flexion capabilities of skin panel, far
Higher than the mechanical property of solid material intensity.
The skin panel and battenboard is Inconel x-750 spring alloy plate, and InconelX-750 alloy master exists
980 DEG C or less have good corrosion-resistant and antioxygenic property, 800 DEG C or less intensity with higher, 540 DEG C or less with compared with
Good resistance to relaxation property, while also there is good forming property and welding performance.
When gradually cellular type bulkhead structure provided by the invention by any direction external force when 1 surface of sandwich plate, first
Part energy is absorbed by battenboard 1-3 in sandwich plate 1 and foamed aluminium filling, converts deformation energy and thermal energy for this energy.
It is internally transmitted by 2-4 and four piece of small panel 2-3 of protrusion again.Plasticity change occurs in stress for slab 2-1 and gradual change circular hole 2-2
Shape weakens impact energy.Finally, due to the inhomogeneities of stress, the transmitting of power is mutually carried out between 4 uniformly distributed slab 2-1, and
When dispersive stress.Reach good shock resistance, antiknock and noise control effect.
Although the present invention has been described by way of example and in terms of the preferred embodiments, they be not it is for the purpose of limiting the invention, it is any ripe
This those skilled in the art is practised, without departing from the spirit and scope of the invention, can make various changes or retouch from working as, therefore guarantor of the invention
Shield range should be subject to what claims hereof protection scope was defined.
