(8) between adjacent cell floorboard bushing pipe, honeycomb floor block and floor frame and car body gap filler.
Implement the embodiment of the present invention, there is following beneficial effect:
Embodiment of the present invention aluminum alloy honeycomb floor take honeycomb structure as the honeycomb sandwich panel of sandwich layer, and its Inspiration Sources is in natural hexagonal honeycomb.The structure due to its uniqueness made with aluminum alloy not only in the other materials of same volume quality the lightest, and rigidity and resistance to overturning very good, also there is sound isolating and heat insulating performance.Aluminum alloy does not have radioactivation, also can not volatilize and anyly can also to recycle completely the disadvantageous pernicious gas of health, economize on resources and the energy, to the near minimum level of the pollution of environment, this makes aluminum alloy honeycomb plate become a kind of energy-saving and environmental protection, healthy new material.
Aluminum alloy honeycomb floor has the feature not available for many conventional floors, mainly contains the following aspects:
(1) quality is light, and density is little: the sandwich layer of bending block is typical open texture, and continuous print polygonal hole lattice present the periodic arrangement of rule, because bending block entity part sectional area is very little, so its density is also very little relative to other sandwich materials.Because bending block density is much smaller than the common sheet material such as laminated wood, steel plate, when volume is identical, its quality is also the lightest.This makes aluminum alloy honeycomb plate be well positioned to meet the requirement of bus to material " lightweight, energy-conserving and environment-protective ".
(2) strength-to-density ratio is high, good rigidly: from amechanical angle analysis, the similar of bending block interconnects in many H-girders, panel is similar to the edge of a wing of H-girder, mainly play bearing surface internal load, honeycomb core is then similar to the web of H-girder, and it mainly rises and bears shearing stress and connection, support top and bottom plate.But honeycomb core is different from the web of H-girder, it is not rare reinforcement but close reinforcement, and sandwich layer distribution is fixed in whole plate face, and sandwich layer aspect ratio plate thickness is much larger, this just makes section moment of inertia also be multiplied, and while raising integral rigidity, resistance to overturning also significantly rises.
(3) shock resistance, vibration reduction and cushioning are good.When bending block is subject to impact effect outside face, impulsive force can be converted into the plastic deformation ability of honeycomb core, so can apparatus with shock absorbing effectively.By carrying out from falling sphere striking experiment to aluminum alloy honeycomb plate, observing indenture area, the indenture degree of depth of impact site, finding impact site flawless, illustrate that the toughness of aluminum alloy honeycomb plate is better, impact resistance is comparatively strong, and the distortion by self absorbs most of energy, and effectiveness in vibration suppression is good.
(4) heat insulation, sound insulation.The material itself manufacturing bending block does not have performance that is heat insulation, sound insulation.But the unique texture of bending block, such that bending block is heat insulation, sound insulation value is good.Nest core is a kind of open texture, and hole lattice account for most space, and for the aluminum alloy honeycomb plate that our this chassis is on probation, it is the aluminum honeycomb panel that the 20mm that makes with the aluminium foil of 0.1mm is thick, and entity part only accounts for 5% of cumulative volume.After honeycomb core and panel are combined into bending block, hole lattice just become hexa-prism confined space, air layer between upper and lower panel is also in numerous closed pore lattice, air is prevented to flow, heat is difficult to propagate in such an embodiment with the form of convection current and radiation, sound wave propagation is also very limited wherein, so bending block has heat insulation, sound insulation value preferably.
(5) waterproof, anti-soak properties are good.Area and the sandwich layer of aluminum alloy honeycomb plate are made by aluminum alloy, and aluminum alloy is nonflammable material, can play good fire-retardant fireproof effect.In addition, the chemical inertness of aluminum alloy own is good, withstanding corrosion, humidity.
(6) good moldability, thickness is optional.The thickness of aluminum alloy honeycomb plate can be selected at 6-100mm according to actual needs, and shape also can make flat board, single panel or snyed plate according to specific requirement.The not only forming of aluminum alloy honeycomb plate, and shaping after not yielding.
(7) pollution-free, energy-conserving and environment-protective.Aluminum alloy is the material preparing aluminum alloy honeycomb plate, and it did not both have radioactivation, also non-volatilely anyly can also reclaim completely the disadvantageous pernicious gas of health, reuse, and economizes on resources and the energy, meets very much the requirement of energy-conserving and environment-protective.In addition, bending block, by alleviating the quality of bus, improves dynamic property while proof strength, reduces burning and consumes, while economize energy, reduce exhaust pollution.
(8) attractive in appearance, easy to clean.The aluminium alloy panel of aluminum alloy honeycomb plate can directly use, and also can obtain shades of colour and pattern by surface coating different coverings.
