In cambered surface.
In a kind of wherein embodiment, foamed aluminium is filled in the hollow structure of the girder.
Honeycomb constructed of aluminium is typical Multi-halfwaves Filters, is typically used as core structure, has good energy absorption characteristics, quilt
It is widely used in the essential industries such as automobile and aerospace field.Previous result of study shows that cellular material receives axial compressive force
When, deform main wired communication deformation, elastic buckling and plasticity collapsing Three models.Wherein plasticity collapsing is honeycomb energy
The main factor absorbed is measured, and the mechanical mechanism of collapse is due to hexagonal honeycomb body axial direction plastic buckling, hole wall is by certain
Wavelength gradually folds, and the wavelength is generally about equal to the hole side length of hexagon.In terms of macromechanics behavior, honeycomb aluminum is by axial pressure
Stress-strain diagram has longer low stress platform area when contracting, is ideal energy-absorbing material.
Foamed aluminium is a kind of strategic new material of rapid rising, is the novel light gold that the mode to be foamed with aluminium alloy produces
Belong to material, have that density is small, specific strength is big, there are many excellent properties such as energy-absorbing buffering, flame-proof explosion-proof.Conventional steel collision prevention girders
When being hit, only intensity is larger before deformation.And after deformation occurs, bearing capacity can decline rapidly, by impact force
It washes away, energy-absorbing effect is very poor, can not protect car body and personnel simultaneously.And foamed aluminium collision prevention girders have excellent energy absorption characteristics, bubble
Foam aluminium is installed between girder steel and vehicle body steelframe.After hitting generation, steelframe, which is pressurized, is transferred to foamed aluminium, foam for Impact energy
Continuous crumple occurs for aluminium, absorbs big energy, and absorb impact force, and protection vehicle frame is injury-free, while protecting interior driving people
Member is not by severe impact.
The utility model has the beneficial effects that this automobile buffer beam can prevent collision prevention girders when slight scraping and collision occurs
Damage, automobile can guide energy-absorption box deformation direction when colliding, and ensure that the stability of energy-absorption box crumple deformation, can
Collision energy is effectively absorbed, occupant safety is kept.
