Embodiment Construction

[0017] exist figure 1 A sound-insulating or damping element 1 according to the invention (which will hereinafter be referred to as a damping element because said element has essentially damping properties and only partially sound-insulating properties) is described in . The damping element 1 is designed as an adhesive element, which is formed in multiple layers from a carrier layer 1.1 and a self-adhesive damping mass 1.2.

[0018] Such a damping element is known in principle from DE 10 2008 050 772 A1. However, the damping element is used here mainly for another purpose, namely to close the opening in the motor vehicle body.

[0019] In a particularly preferred configuration, the carrier layer 1.1 is formed from a so-called 5xxx aluminum alloy which has a magnesium content of 0.2% to 6.2%. 5xxx aluminum alloys are characterized by a high strength, which lies at 100 N / mm 2 to 450N / mm 2 in the range.

[0020] Instead of using a 5xxx aluminum alloy, the carrier layer 1.1 is...

Abstract

The invention relates to a method for reducing the natural vibration of a component (2). According to the invention, a vibration behavior of the component (2) is determined at positions having vibration amplitudes exceeding a predefined limit value, and one damping element (1) is attached locally at each, said element being designed as a multilayer adhesive element having a carrier layer (1.1) and a self-adhesive damping mass (1.2). The invention further relates to a damping element (1) for reducing the natural vibration of a component (2). According to the invention, the damping element (1) is formed as a multilayer adhesive element made of a carrier layer (1.1) and a self-adhesive damping mass (1.2), wherein the carrier layer (1.1) is formed of a flexurally rigid material and the damping mass (1.2) is preferably formed of butyl rubber.

Description

technical field [0001] The invention relates to a method for reducing the natural vibrations of components and a sound-insulating or damping element for reducing the natural vibrations of components. Background technique [0002] It is generally known from the prior art to reduce driving noise in the vehicle interior by applying various sound-absorbing materials, such as sound-insulating or damping mats, and sprayable sound-absorbing blocks to vehicle components. In order to generate sound insulation by means of sound-insulating or damping mats, large-area mats are placed on the vehicle components at designated points and subsequently melted onto the floor at the process temperature. The vehicle component thus stiffens locally. [0003] Furthermore, it is generally known from the prior art to use openings in body components to carry out various work steps, such as fastening body components and carrying out corrosion protection measures, during the manufacture of vehicle bod...
