The damping of the dynamic vibration absorber. [PDF]
Sci RepThe design parameters of the dynamic vibration absorber notably affect the motion space of the main system. A complete new universal method of attaining the explicit exact solution to the optimum damping was proposed to enhance the accuracy of calculating the dynamic vibration absorber's parameters.

Characteristics of adjustable dynamic vibration absorber
Transactions of the JSME (in Japanese), 2016 One of effective ways to suppress vibration of a mechanical system is using a dynamic vibration absorber. The dynamic vibration absorber consists of a mass, a spring and a damper. The optimal tuning of natural frequency and damping ratio of the dynamic vibration absorber is required to suppress vibration, so adding an adjustable mechanism of stiffness ...

Vibration Characteristics Analysis of Boring Bar with Tunable Dynamic Vibration Absorber. [PDF]
Materials (Basel)In deep-hole boring processes, boring bars with a large length-to-diameter ratio are typically employed. However, excessive overhang significantly reduces the boring bar’s stiffness, inducing vibrational effects that severely degrade machining precision and surface quality.

Beamlike dynamic vibration absorbers [PDF]
The Journal of the Acoustical Society of America, 1981 Although the concept of the dynamic absorber and its potential for vibration reduction were first discussed in the early part of this century, John Snowdon's comprehensive work in this area was certainly a pioneering effort. By rephrasing the standard equations in terms of complex dynamic moduli, it became possible to treat viscoelastic (rubberlike ...

Dynamic vibration absorber for shaft machining [PDF]
MATEC Web of Conferences, 2020 The article is concerned with a new method that minimizes the vibration level of non-rigid axisymmetric parts on lathes. A schematic diagram of the vibration absorber control path is given. Its configuration is changing due to fictitious elastic stiffness parameters, as well as damping and the part–support subsystem weight.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1995 A new type of balancing machine is proposed which uses a dynamic vibration absorber as a device measuring unbalance. When an unbalanced rotor rotates, centrifugal forces are generated which result in sinusoidal forces being transmitted to the supporting structure.

Energy Harvesting Dynamic Vibration Absorbers
Journal of Applied Mechanics, 2013 Energy harvesting is a promise to harvest unwanted vibrations from a host structure. Similarly, a dynamic vibration absorber is proved to be a very simple and effective vibration suppression device, with many practical implementations in civil and mechanical engineering. This paper analyzes the prospect of using a vibration absorber for possible energy

Dynamics of a Cubic Nonlinear Vibration Absorber
Nonlinear Dynamics, 1999 Abstract We study the dynamics of a nonlinear active vibration absorber. We consider a plant model possessing curvature and inertia nonlinearities and introduce a second-order absorber that is coupled with the plant through user-defined cubic nonlinearities.
