Definitions

  • the invention relates to a design of plate-shaped hollow profiles, which consist of flange and web-shaped sub-segments and are provided in particular for the construction of vehicle cells.
  • BE-A-447 505 discloses a plate which can be fastened to the walls and the ceiling of auditoriums, for example concert halls, with the aid of which the room acoustics are to be improved.
  • the plate has a corrugated cross-sectional profile with different wall thicknesses as well as different wave heights and distances between the respective waves. This allows the cladding panel to absorb sound waves of multiple frequencies.
  • the invention has for its object to design a profile of the generic type so that the vibration behavior, the structure-borne noise and the sound radiation of constructions thus created are significantly improved.
  • the profile has different substructure natural frequencies over its entire cross-sectional width or within periodically repeating areas due to the uneven geometry of its flange-shaped and / or web-shaped sub-segments.
  • Embodiments of the invention are shown in the drawing and are described in more detail below.
  • 1 to 5 each show the central surfaces of the generating geometries of different profiles.
  • each of these profiles has either geometrically unequal subsegments over their entire cross-sectional width or - as shown here - within periodically repeating areas with the length L w (full or periodically recurring asymmetry).
  • the flange-shaped subsegments 1 and the web-shaped subsegments 2 each have the same wall thickness.
  • the web-shaped subsegments 2 each meet at different angles with the flange-shaped subsegments 1; the nodes are thus offset from those of a symmetrical profile shown in broken lines by the distances a, b and c.
  • L1 to L12 the different lengths of the web or flange-shaped sub-segments are designated. In this way, a defined asymmetry with a not equal to b, a not equal to c and b not equal to c is generated.
  • the web-shaped subsegments 2 are of the same length L 1 and are arranged at right angles to the flange-shaped subsegments 1.
  • the generating geometries of the web-shaped subsegments 2 each have a different distance - see L2 to L5 of the flange-shaped subsegments 1 - to one another. Similar to FIG. 1, there is also an offset by the distances a and b. 2, the same wall thicknesses are preferred, in FIG. 3 different wall thicknesses h 1, h 2 for the flange-shaped subsegments 1 and different wall thicknesses h 3 to h6 of the web-shaped subsegments 2 are provided. Combinations between Fig. 2 and Fig.
  • Fig. 4 discloses a hollow profile with the same Bar distances L2 within the repeat length L w .
  • the extrusion profile shown in FIG. 5 has thickening 1a, 2a (noses) of different volume which influence the frequency and in an asymmetrical arrangement.

Claims (6)

1. Conformation de profilés creux en forme de plaques qui sont constitués par des membrures en forme de semelles et d'entretoises (1, 2) et qui sont prévus en particulier pour la construction de cellules de véhicules, caractérisée par le fait que le profilé présente, sur la totalité de la largeur en section transversale ou à l'intérieur de zones (Lw) qui se répètent périodiquement, et grâce à une géométrie inégale de ses membrures en forme de semelles et/ou d'entretoises (1, 2), des fréquences de résonance des sous-structures qui sont différentes.
2. Profilé creux selon la revendication 1, caractérisé par le fait que les membrures en forme d'entretoises (2) sont à chaque fois disposées de manière asymétrique.
3. Profilé creux selon la revendication 2, caractérisé par le fait que les membrures en forme d'entretoises (2) rencontrent à chaque fois les membrures en forme de semelles (1) sous des angles différents.
4. Profilé creux selon la revendication 2, caractérisé par le fait que les membrures en forme d'entretoises (2) sont disposées à angle droit par rapport aux membrures en forme de semelles (1), et qu'elles présentent à chaque fois une distance différente l'une par rapport à l'autre.
5. Profilé creux selon l'une des revendications 1 à 4, caractérisé par le fait que les membrures en forme d'entretoises (2) et/ou les membrures en forme de semelles (1) présentent à chaque fois une épaisseur différente.
6. Profilé creux selon l'une des revendications 1 à 5, caractérisé par le fait que les membrures en forme d'entretoises (2) et/ou les membrures en forme de semelles (1) présentent des épaississements (2a, 1a) qui influencent la fréquence, dont les volumes sont à chaque fois différents et/ou qui sont disposés de manière symétrique.
