Embodiment Construction

[0038] figure 1 The tunable mass damper 100 is shown schematically. The tunable mass damper 100 includes a housing 1 . Inside the housing 1, a mass block 2 is arranged. The mass 2 is guided by the two guide rails 31 and 32 of the guide part 3 . Guide rails 31 and 32 are installed on the housing 1 . The housing 1 may comprise, in addition to the four side walls as shown, a top and a bottom plate to provide a closed, preferably airtight housing 1 .

[0039] The direction of action A is depicted with an arrow. The arrows indicate forward and backward. The first pair of connecting rollers 21 , 22 and the second pair of connecting rollers 21 ′, 22 ′ are respectively arranged on the front side and the rear side of the proof mass 2 .

[0040] Four pairs of guide rollers 11 , 12 ; 13 , 14 ; 11 ′, 12 ′; 13 ′, 14 ′ are arranged in and mounted on the housing 1 .

[0041] The first force transmission part is provided as a metal cord 6 . The metal rope 6 is guided through the rolle...

Abstract

The present invention relates to tunable mass dampers and mounting assemblies for damping vibrations. The present invention relates to tunable mass dampers for damping vibrations. The tunable mass damper (100) comprises: a mass (2) for providing an inertial mass; and at least one guide part (3) for guiding the mass along a direction of action (A) (2) Movement. The tunable mass damper (100) comprises at least one force transmission part (6), which is arranged transversely to the direction of action (A). The mass (2) is displaceable in said direction of action (A) and is connected to the force transmission part (6) by connecting means. The force transmission part (6) is pretensioned by at least one spring element (4), wherein the pretensioning is adjustable.

Description

technical field [0001] The present invention is directed to tunable mass dampers and mounting assemblies. Background technique [0002] Mass dampers are used to reduce the amplitude of mechanical vibrations. A tuned mass damper is a mass damper that is specifically dimensioned for a specific application, eg, for a specific purpose, and thus can only function properly at a single frequency. [0003] Attempts have been made to provide tuned mass dampers which can then be adjusted after being fitted to a particular component. [0004] Such a device is disclosed in US 6,681,908 B2. This patent discloses an adjustable tuned mass damper having a mass supported on a coil spring. The natural resonance frequency of the system can be adjusted with a screw, which must be screwed into the helical spring. The screw grabs one or more coils of the spring and thus changes the spring's stiffness. [0005] The prior art suffers from several disadvantages. The more screws are screwed int...
