20160123422 | Self-tuned mass damper and system comprising the same - A simple self-tuned mass damper is hereby proposed for a broadened frequency band and which can be adapted to large and expensive structures as well as small and inexpensive structures alike. The novel self-tuned mass damper includes an auxiliary mass and a non-linear suspension, which is configured to connect the auxiliary mass to a vibrating structure. The mass of the auxiliary mass and the stiffness of the non-linear suspension are selected such that the natural frequency is at least 6 Hz and that the amplitude of the relative displacement of the auxiliary mass in respect to the vibrating structure is at most 12 mm. | 05-05-2016 |

20160377140 | BORING BARS AND METHODS OF MAKING THE SAME - In one aspect, damping systems are described herein. Such damping systems can employ internal dynamic vibration absorbers. For example, a damping system described herein comprises a monolithic bar extending from a first end to a second end along a longitudinal axis. The monolithic bar comprises an enclosed cavity positioned therein. The damping system further comprises a dynamic vibration absorber disposed in the enclosed cavity. The dynamic vibration absorber includes an absorber mass and an elastomeric buffer arranged in spacing between one or more surfaces of the absorber mass and cavity wall. | 12-29-2016 |
