Specific embodiment
Below by attached drawing, the present invention is described in detail.
As shown in Figure 1, the present invention provides a kind of duck's foot type shock resistance bulkhead structure, including two parallel sandwich plates 1,
Duck's foot type shock resistance structure 2 is equipped between two sandwich plates 1.
As shown in Fig. 2, the duck's foot type shock resistance structure 2 includes two duck's foot type structures and intermediate base 2-1, it is described
Duck's foot type structure include in four slab 2-2 and four small panel 2-3, the small panel 2-3 be duck's foot type, described four
A slab 2-2 is uniformly distributed, and each described one end slab 2-2 is fixedly connected with intermediate base 2-1, the other end and described one
A small panel 2-3 connection, the small panel 2-3 are fixedly connected with sandwich plate 1.The duck's foot type structural strength is high, and ties
Structure is simple, and shock resistance is good.Duck's foot type structure described in two is symmetrical about intermediate base 2-1, disperses convenient for stress, and inhales
The vibrational energy of receipts is more.
It is the intermediate base 2-1 and slab 2-2, the slab 2-2 and small panel 2-3, small for better effect
Panel 2-3 and sandwich plate 1 are all to be welded to connect.
For better effect, the intermediate base 2-1, slab 2-2, duck's foot type small panel 2-3 use yield strength
For the 50CrNi5MoV martensite steel of 1350MP.The martensite steel has good plasticity and high temperature resistant, ensures enough
Structural strength and high temperature resistance.
As shown in figure 3, sandwich plate 1 includes upper and lower skin panel 1-1 and intermediary cellular battenboard 1-2, the skin panel
1-1 and honeycomb sandwich board are Inconel x-750 spring alloy plate, and InconelX-750 alloy master has at 980 DEG C or less
Good corrosion-resistant and antioxygenic property, 800 DEG C or less intensity with higher, 540 DEG C or less have preferable resistance to slackness
Can, while also there is good forming property and welding performance.
The honeycomb sandwich board 1-2, cellular sandwich are separated into numerous a closed cells, prevent air to flow, make heat
It is greatly hindered with sound wave, therefore, plays the effect of heat-insulated, sound insulation, damping of preventing fires.And have light specific gravity, intensity high, rigid
