Abstract

Provided herein is a vibration reducing sheet comprising a damping patch (101), a stiffening patch (102), and a substrate (103). The substrate is connected to the damping patch and the stiffening patch, and in some embodiments, the damping patch and the stiffening patch do not contact one another. The sheet can be connected to a base structure that is prone to vibrations. Because the damping patchand the stiffening patch can thus be applied to different locations of the base structure, the two patch types can independently be positioned to provide enhanced vibration reduction and mitigation.

Description

technical field [0001] The present invention generally relates to a damping plate for reducing the frequency and / or amplitude of vibrations of a substructure to which it is applied. Background technique [0002] In many markets, such as the automotive market, home appliance market, and electronic equipment market, there is a need to reduce the generation of unwanted vibrations and associated noise. For example, the automotive industry is trending increasingly towards lighter weight vehicles. Therefore, lighter weight aluminum and polymer materials are increasingly used. However, these designs and the use of materials increase the problems associated with vehicle vibration and vibration-related noise. [0003] Typically, noise and vibration issues have been managed through two approaches: strengthening the structural geometry to be more resistant to vibrations, and damping the structure to reduce vibration amplitudes. Along with these solutions, acoustic technologies can b...
