Description
Technical field
The utility model is related to automobile technical field, more particularly to a kind of vehicle body knot of application different size damping clad plate
Structure and automobile.
Background technology
Lightweight, high-performance, low energy consumption and safety and comfort are the inexorable trends of automobile industry development, but with lightweight skill
The development of art and the application of lightweight body structure, while vehicle dynamic quality and fuel economy is improved, also bring therewith
The inferior position that body vibrations increase, internal car noise grade particularly low frequency configuration noise is improved.Increase vibration damping sound insulation annex with tradition
Compare, using Multifunctional compatible electrical material --- the shock-resisted complex steel sheet with shock-absorption sound-insulation advantage, can yet be regarded as a kind of important
Engineered solution, the program can not only realize performance boost, system optimization and lightweight, also with by objective optimization reality
The potential advantages of existing cost control.
Damping clad plate (steel plate) constrains metallic plate (steel plate) and presss from both sides one layer of polymer damping material by upper and lower two-layer high intensity
Constitute, its application form is the exploitation that parts are carried out in vibration and noise occasion alternative metals sheet material.Shock-resisted complex steel sheet
Between (0.3~2.0) mm, between (25~150) μm, its structure is as schemed for damping layer thickness for metal single layer plate thickness
Shown in 1.
The formability of sheet metal is to realize that punching press parts prepare feasible important leverage, many for " sandwich "
The shock-resisted complex steel sheet of Rotating fields, is in a thickness direction non-homogeneous non-individual body, but there is performance mutation layer, makes multilayer material
Material thickness direction upper stress skewness；And because the bending radius of levels steel plate is different, make to produce a shearing in intermediate layer
Power, causes upper and lower panel to produce the changing of the relative positions；Making the forming accuracy of parts reduces, and influences the reliable durable performance of part.While because
Shock-resisted complex steel sheet single sheathing thickness is the half of institute's alternative metals sheet metal thickness, causes composite formed performance reduction,
Stiffness.
Wherein, damping clad plate (steel plate) is as follows with the forming characteristic of common metal plate (steel plate) and variance analysis：Pass through
Erichsen test analyzes stress of the sheet metal under specific molding condition, strain and deformation, analysis contrast
The similarities and differences and subject matter point of damping clad plate and common metal sheet material.Issued in plane stress for common metal plate and changed
Shape, the instability in tension (constriction is until cracking) that its failure mode is mainly with tension when being leading, the primary deformable ring of sample
Save as flexural deformation, cupping formation, ring-type constriction and produce rupture.Corresponding mechanical process is broadly divided into four deformation stages：
Elastic bending, plastic bending, thin plate are upheld and are ftractureed.
Mechanical process for substrate thickness identical damping clad plate (steel plate) is essentially identical with general steel plate, but because
" sandwich " formula sandwich construction is in a thickness direction non-homogeneous non-individual body, but there is performance mutation layer, prevents it from making
There is continuous modification for overall；Simultaneously because there is the consumption effect of deformation energy during the displacement transfer in intermediate layer and deform stagnant
Phenomenon afterwards, therefore cause during AEG-process damping clad plate (steel plate) Erichsen number between individual layer steel plate and same base thickness of slab
Between the conventional steel plates of degree, and there is the levels steel plate nonsynchronous phenomenon of cracking.
For the deformation process of damping clad plate (steel plate), with the increase of load, because of the bending radius of levels steel plate
Difference, makes to produce a shearing force in intermediate layer, causes upper and lower panel to produce the changing of the relative positions, maximum changing of the relative positions amount and single sheathing and centre
Layer relative thickness is related, and top layer steel plate thickness is bigger, or intermediate layer thickness is bigger, and changing of the relative positions amount is also bigger.Damping clad plate (steel
Plate) changing of the relative positions of upper and lower panel in forming process, the stability of influence parts forming accuracy and parts quality.
Damping clad plate (steel plate) Stress non-homogeneity Distribution Phenomena in a thickness direction, makes upper and lower panel mechanical property not
Together, cause the molding condition difference of levels steel plate big.Because of damping layer absorption consumption in deformation energy transmittance process under usual conditions,
Upper strata steel plate crackle is caused to occur lagging behind lower floor's steel plate.The parts big, complex-shaped for shaping book size, easily cause
Part forming Quality Down, the problems such as percent defective is high.
Further, damping clad plate (steel plate) is analyzed as follows with the difference on effect of the vibration and noise reducing of general steel plate：
When sound wave runs into barrier in route of transmission, due to the change of dielectric property impedance, shielded part acoustic energy
Barrier reflects, and partly by barrier sorption enhanced for thermal energy consumption is dissipated, only some acoustic energy can be transmitted to through barrier
In another space.The sound insulation effectiveness in vibration suppression of general steel plate and damping clad plate (steel plate) as shown in Figure 2 a and 2 b, therefore by every
Sound principle can be obtained：Ii=Ir+I α+It, wherein：Ii is incident acoustic energy；Ir is reflection of the acoustic energy；I α are sorption enhanced acoustic energy；It is
Transmission acoustic energy；Damping clad plate (steel plate) increased visco-elastic damping layer thickness compared with general steel plate thickness, and (individual layer steel plate is thick
It is general steel plate thickness half to spend).Contrast soundproof principle formula (1) and two kinds of material structures understand, incident acoustic energy Ii and reflection
Acoustic energy Ir is equal, two kinds of material sorption enhanced acoustic energy I α exist it is significantly different, damping clad plate (steel plate) except plate body in itself
Outside acoustic energy absorption effect, damping clad plate (steel plate) extra vibration damping and energy-absorbing effect because its sandwich construction and material property have.Its
Cardinal principle is to be remarkably decreased the high damping characteristic with macromolecular material in material property change in the instantaneous impedance interface acoustic energy step, most
Realize that the sorption enhanced acoustic energy of damping clad plate (steel plate) is significantly increased eventually, transmission acoustic energy It is substantially reduced.
