TL;DR: In this article, the dynamic vibration absorber has been shown to be a very useful method of limiting vibration of excessive amplitude and damping a dynamic absorber can be made to be effective over a large range of forcing frequencies.
Abstract: The dynamic vibration absorber has been shown to be a very useful method of limiting vibration of excessive amplitude. It has been shown that by addition of damping a dynamic absorber can be made to be effective over a large range of forcing frequencies. The equations relating to optimal dynamic vibration absorbers are developed and applied to a particular case.

TL;DR: In this paper, a vibration isolator is disclosed which is particularly effective to isolate low frequency vibrations, in a preferred form it is an elastically deformable container with a partial vacuum therein.
Abstract: A vibration isolator is disclosed which is particularly effective to isolate low frequency vibrations. Basically, in a preferred form it is an elastically deformable container with a partial vacuum therein. The isolator is disposed between an object which is to be vibration isolated, and a fixed support. Several isolators can be used in parallel. In one form, the vibration isolator comprises an elastic bellows extending between two rigid members. Further improved performance can be obtained by coupling the vibration isolator to a vacuum reservoir.

TL;DR: In this article, a simple piece of bolt-on hardware can stop resonant vibration in products ranging from huge machine tools to small blowers, and a dynamic damper provides a synchronized stabilizing force that cuts overall vibration to a small fraction of the undamped motion.
Abstract: A simple piece of bolt-on hardware can stop resonant vibration in products ranging from huge machine tools to small blowers. This remedy is actually the most sophisticated and efficient approach to the problem. Properly tuned, a dynamic damper provides a synchronized stabilizing force that cuts overall vibration to a small fraction of the undamped motion.
