Abstract
A vibration damped enclosure comprises side walls and a vibration damping plate structure which extends across the enclosure and is attached to internal surface portions of a first and a second side walls. The vibration damping plate structure (2) comprises a non-rigid layer (12) sandwiched between two rigid layers (13, 14), wherein each rigid layer between the first and second side walls (5, 6) comprises at least one cut (15, 16) through the rigid layer (13, 14) which makes the extension of each rigid layer between the first and second sidewalls (5, 6) discontinuous.

A vibration damped enclosure, comprising side walls and a vibration damping plate structure extending across the enclosure and attached to internal surface portions of a first and a second side wall, wherein the vibration damping plate structure (2) comprises a non-rigid layer (12) sandwiched between two rigid layers (13, 14), and wherein each rigid layer between said first and second side walls (5, 6;
- 22, 23) comprises at least one cut (15, 16) through the rigid layer (13, 14) which makes the extension of each rigid layer between the first and second sidewalls (5, 6) discontinuous, wherein the at least one cut (15, 16) extends completely through an adjacent non-rigid layer (12).
Use of a damping plate structure (2) comprising a non-rigid layer (12) sandwiched between two rigid layers (13, 14), wherein each rigid layer comprises at least one cut (15, 16) through the rigid layer (13, 14) which makes the extension of each rigid layer between the first and second sidewalls (5, 6;
- 22, 23) discontinuous, wherein the at least one cut (15, 16) extends completely through an adjacent non-rigid layer (12), for vibration damping of an enclosure, especially an automotive enclosure article.
A vibration damped enclosure, comprising side walls and a vibration damping plate structure extending across the enclosure and attached to internal surface portions of a first and a second side wall, wherein the vibration damping plate structure (2) comprises a non-rigid layer (12) sandwiched between two rigid layers (13, 14), and wherein each rigid layer between said first and second side walls (5, 6;
- 22, 23) comprises at least one cut (15, 16) through the rigid layer (13, 14) which makes the extension of each rigid layer between the first and second sidewalls (5, 6) discontinuous, wherein the at least one cut-extends along the whole width of the damping plate.
Use of a damping plate structure (2) comprising a non-rigid layer (12) sandwiched between two rigid layers (13, 14), wherein each rigid layer comprises at least one cut (15, 16) through the rigid layer (13, 14) which makes the extension of each rigid layer between the first and second sidewalls (5, 6;
- 22, 23) discontinuous, wherein the at least one cut extends along the whole width of the damping plate, for vibration damping of an enclosure, especially an automotive enclosure article.
