Vibratory arrangement for damping a vibrating wall

摘要

The invention relates to a vibratory arrangement for damping a vibrating wall, comprising a plurality of vibrators which are distributed on the surface of said wall, at a distance therefrom, vibrate in antiphase with respect to the wall, are in the form of plates and are connected to the vibrating wall by coupling members. The invention is characterised in that the vibrators are angled profile bars (1) which are produced from sheet sheet by cold forming and exhibit in each case one principal leg (2) which is planar up to its free edge (4), a transverse leg (3) which is arranged perpendicularly with respect to the principal leg (2), and a transverse web (6) which connects principal leg (2) and transverse leg (3) via two curved sections (5, 7) which are curved in opposite directions. The angled profile bars (1) are positioned at right angles on the wall (11), and welded thereto, in each case by the free edge (4) assigned to the principal leg (2). <IMAGE>
