Damping structureDamping structure description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090126289, Damping structure. Brief Patent Description - Full Patent Description - Patent Application Claims
The present disclosure relates to subject matter contained in priority Korean Application No. 10-2007-0113848, filed on Nov. 8, 2007, which is herein expressly incorporated by reference in its entirety. 1. Field of the Invention The present invention relates to a damping structure which is capable of effectively damping vibration of structures. 2. Background of the Invention Vibration of a structure causes great damage to a workplace. The vibration of the structure causes a noise. And, the noise may cause a noise-induced hearing loss to workers, which takes the first rank in vocational diseases and causes the workers to shirk working in a manufacturing part. Also, the vibration causes weariness and cracks to the structure such as a manufacturing plant. In addition, due to the vibration, it may be difficult to perform precise processes. Various methods for suppressing vibration of a structure have been proposed so far. One of them is using a special alloy having a high vibration damping (absorbing) force in itself. However, this method requires composition of the special alloy and a special process, thus it is seriously difficult to satisfy all of a cost, a mechanical performance and vibration suppression performance. Various alloys, such as Fe—Al based, Fe—Cr based, Mn—Cu based alloys, have been developed, however, they have hardly been commercially used. As another method, a composite resin metallic plate in which a resin is interposed between metallic plates, that is, a sandwich steel plate structure is proposed. This structure implements excellent damping characteristic and mechanical performance. However, a special device is required for fabrication, which causes a fabrication cost to increase. And, it has an inferior welding or molding characteristic, thus it has a limitation to be used. Besides, there are a method for increasing a mass and stiffness using a thick material and a method using a cover or a noise suppresser. However, these methods respectively have drawbacks that a weight may increase and that it is effective only in a limited space. Therefore, a first object of the present invention is to provide a damping structure which is excellent in aspects of a cost, a mechanical characteristic and vibration damping performance and has compatibility with various devices. A second object of the present invention is to provide a damping structure which is capable of being easily fabricated because it can be installed only by a simple process and of reducing an installation cost and time. Particularly, the damping structure according to the present invention is configured to be installed in a state that a structure to be damped is an end product, accordingly it is capable of obtaining a damping effect by simply installing the damping structure without changing a structure of a pre-fabricated device. A third object of the present invention is to provide a damping structure which is capable of substantially damping vibration without increase of a weight and of being installed regardless of an installation space. A fourth object of the present invention is to provide a damping structure which is capable of damping vibration of a structure formed by a thick metallic plate or a container for storing liquid. To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a damping structure comprising a vibration controlling medium fixed at a structure and vibrating with an amplitude greater than that of the structure upon vibration; and a damper vibrating separately from the vibration controlling medium as a result of being loosely fitted into the vibration controlling medium or a damper supporter extended therefrom, and thus having a vibration frequency different from that of the vibration controlling medium. The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings. The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.
