- modern motor vehicles are provided with acoustically effective linings in order to reduce the engine noises emitted towards the exterior
- this publication concerns an acoustically effective part such as is used in the aeroplane industry
- this part comprises a core layer with a honeycomb structure, whose individual cavities communicate acoustically with each other via drainage openings
- This core layer is bounded on the one side by a perforated or open-celled cover layer in order to be acoustically effective
- This assembly is not suited in any way for shock absorbing functions
- An analogue acoustically effective assembly is disclosed in FR-2,727, 189
- This assembly also comprises a core layer having a honeycomb structure which can be filled with an open-celled foam, and which is provided on both sides with outer cover layers made of an open-celled synthetic foam
- This assembly is used for sound insulation in buildings and does not exhibit any particular shock absorbent properties
- Analogue assemblies for use in any passenger vehicles are also known, for example, from DE-U- 296,07,262
- the element disclosed in this publication is used as a roof liner in motor vehicles
- This element comprises a honeycomb layer as a core layer and on both sides of this core layer comprises a cover layer made of fibrous material These cover layers are melted onto the honeycomb layer and, due to the material bonding, result in an increased stiffness of the entire element
- This arrangement provides stability, provides an enhanced tensile strength but does not have any particular acoustic or shock absorbing properties
- CH-692,731 discloses an ultralight package for use in vehicles, which combines shock and sound absorbing properties This package is suitable for protecting passengers and is preferably used in the crash sensitive part of the foot space This package does not have any particularly stiffening properties and is only laid into the existing vehicle space
- the vehicle body part according to the invention comprises a substructure and an outer skin, whereby said substructure comprises a core layer, preferably a honeycomb-like core layer
- This core layer, on the noise emission side comprises an open-celled first cover layer and a second cover layer on the outer skin side
- This substructure is attached to the outer skin by means of suitable attachment means
- the HPC-value of the entire self- supporting vehicle body part is less than 1000
- the air flow resistance of the cover layer on the noise emission side is between 200 and S000 Ns/m 3
- HPC-value is defined as follows
- a the resultant acceleration is a multiple of "g" t1 and t2 the two time instants (in seconds) during the impact, defining the beginning and the end of the recording for which the value of HPC is a maximum
- the accelerations in the x-, y- and z-directions are measured for the center of gravity of the pedestrian's head and the resultant acceleration is calculated
- the HPC-value can be determined based on the above formula, i e by integrating the resulting acceleration over time
- the HPC-value is a dimension-free value
- inventive car body part can be designed as a self-supporting motor bonnet, as a self-supporting trunk lid or as a self-supporting vehicle roof, and can be applied to any type of vehicle for road or rail transport
- Fig 1 shows a schematic view of a vehicle body part according to the invention
- Fig 2 shows a schematic view of a vehicle body part according to the invention having local fixation means
- Fig 3 shows a schematic view of a vehicle body part according to the invention having additional shock absorbent elements
- Fig 4 shows comparative measurement curves for the time-dependent progression of impact delay
- Fig 5 shows a schematic view of a vehicle body part according to the invention comprising a substructure with locally arranged omega-shaped deformations, and
- FIG 6 shows a schematic view of a vehicle body part as shown in Fig 5 comprising a substructure having locally compressed areas
- the assembly according to the invention is schematically shown in Figure 1
- This Figure shows a self-supporting vehicle body part 1 with a honeycomb-like core layer 2, which comprises an open-celled covering layer 3 on the engine compartment side and a covering layer 4 on the outer skin side, said covering layer 4 on the outer skin side being bonded to an outer skin 6 by means of a bonding or adhesive agent
- the assembly comprising the honeycomb-like core layer 2 and both covering layers 3, 4 is hereinafter called the substructure 7
- the core layer 2 is preferably made of cardboard, aluminium, Nomex® or other deformable materials, in particular made of plastic materials such as PA, polyester, PL) It is evident that other suitable materials be used, such as recycled or corrugated cardboard or TS-foam (PU- or polyamide-based foam) or TP-foam (EPP, Notyl® EEF or similar) or metallic foams
- the required stiffness of the inventive self-supporting vehicle body part 1 is essentially defined by the stiffening effect of the substructure 7
- the expert will compile a suitable choice of designs, materials, thickness and stiffness of the individual layers
- the expert will consider to choose a suitable thickness, cell size, compression resistance or material for the honeycomb-like layer, whilst taking into consideration the nature of material, the surface weight, the bonding strength of the skin
- the acoustic efficacy of the inventive vehicle body part 1 is essentially defined by the acoustic properties of the substructure 7
- the open celled cover layer 3 has an air flow resistance of between 200 to 5000 Ns/m 3
- the substructure 7 can - at least locally - be provided with further honeycomb-like or foam layers 8 and additional fibrous layers 9, as is seen in Figure 3
- the vehicle body part 1 can be provided with further elements, and in particular with additional elements 1 1 for attaching hinges or other closure elements, as shown schematically in Figure 2
- the vehicle body part 1 can be provided with a thermal protection, in particular with an aluminium foil
- EMC protection electromagnetic waves
- Figure 4 shows measurement curves of the time-dependent progression of the impact delay for several different arrangements
- the critical HPC (head performance criteria) value is measured for the head of a child's body, the head weighing 3 5 kg (or for the head of an adult's body, the head weighing 4 8 kg), and at an impact velocity of 35 km/hr
- This value should be less than one thousand (HPC ⁇ 1000) in order to meet the guidelines for shock absorption of the European automobile industry
- Figure 5 shows a schematic view of a vehicle body part according to the invention comprising a substructure with a locally arranged omega-shaped deformation This design is useful to increase the stiffness of the entire vehicle body part
- the geometry of such a shaped substructure is adjusted such that the HPC-value remains below 1000
- a local padding or local substructures 8 can be added
- Figure 6 shows the vehicle body part as shown in Figure 5, comprising locally compressed areas 12, 13, which allows to vary the stiffness of the substructure In particular this further allows to decrease the first peak of the dynamic force deflection It is understood that the claimed substructure can be covered at least locally with an aluminium film to assure a good thermal resistance
- this substructure is covered by a nonwoven fabric or a foil, which can be removed after painting, if this vehicle body part is assembled before painting.
- the expert will take into consideration to design the substructure comprising structural folds or to provide this substructure with fire-resistant, chemical-resistant and humidity-resistant additives
- the structure according to the invention can be designed and dimensioned in such a manner that future norms for the protection of pedestrians according to ACEA and/or EEC WG17 can be met, or that equivalent rules in other countries (USA, Japan etc ) are met
- the current rules concern only a crash on to a windscreen and are not mandatory or are merely facultatively applicable to motor bonnets
- this vehicle body part can be designed as a headlmer which fulfils the FMVSS 201 regulations
- the present invention allows a more compact vehicle construction, in that the vehicle body part can be arranged closer to the engine block or to another rigid element (aggregate, battery, or similar) This is ensured, in particular, by an increased energy absorption caused by a deformation of the entire self-supporting vehicle body part, as well as by the progressive compression behaviour of the substructure In this way, the spacing between the engine block or any other rigid vehicle element can be reduced by 25% without exceeding the prescribed HPC-value (or HIC-value, i e head injury crite ⁇ um)
