Adaptive tuned vibration absorber
… and applied to a previously designed tunable vibration absorber. The adaptive vibration absorber is capable of detecting the frequency of the driving force and tuning itself automatically to that particular frequency. The primary structure was previously designed to obtain a certain natural …

New design of tuned vibration absorber for wide frequency range application
Vibrations are undesirable in machines and structures because they increased stresses, energy losses, cause added wear, increase bearing loads, induce fatigue, create passenger discomfort in vehicles. Uncontrolled vibrations can leave a bad impression to the machine, structure, and human. Vibration …

Energy Redistribution with Controllable Binary State Latch Element
… is introduced in this thesis. Unlike traditional tuned vibration absorber, the latch device can be viewed as variable semi-active dampers such as magnetorheological (MR) and piezoelectric friction dampers. The distinct difference between other semi-active dampers and our latch device is that other …

Characterization of an Electromagnetic Tuned Vibration Actuator
Tuned vibration absorbers (TVA) have been discussed in literature since the early twentieth century. These devices are implemented to suppress the system's vibration by transferring energy to the absorber mass. This research examines an electromagnetic tuned vibration absorber that can have its …

Vibration control using an adaptive tuned magneto-rheological fluid vibration absorber
An adaptive tuned vibration absorber (ATVA) can be used to suppress unwanted vibrations. If the excitation frequency is time harmonic but the frequency changes with time,it is desirable to retune the ATVA so that the natural frequency of the ATVA always coincides with the excitation frequency. One …

Using Magneto-Rheological Dampers in Semiactive Tuned Vibration Absorbers to Control Structural Vibrations
Since their invention in the early 1900s, Tuned Vibration Absorbers (TVAs) have shown to be effective in suppressing vibrations of machines and structures. A vibration absorber is a vibratory subsystem attached to a primary system. It normally consists of a mass, a spring, and a damper. Mounted to …
