EXPERIMENTAL OBSERVATION OF NONLINEAR VIBRATIONS USING A CLOSED-LOOP VIBRATION SYSTEM
(Polish Acad Sciences, 2015-12-01)
This paper presents experimental observation of nonlinear vibrations in the response of a flexible cantilever beam to transverse harmonic base excitations around its flexural mode frequencies. In the experimental setup, ...
Some diverse examples of exploiting the beneficial effects of geometric stiffness nonlinearity
(2019-06-15)
The effects of nonlinearity, particularly stiffness nonlinearity, has been of concern to structural engineers for many years. The main reason for this is because this type of nonlinearity can cause unpredictable dynamics, ...
Experimental characterization of a nonlinear vibration absorber using free vibration
(2016-04-14)
Knowledge of the nonlinear characteristics of a vibration absorber is important if its performance is to be predicted accurately when connected to a host structure. This can be achieved theoretically, but experimental ...
A comparison of two nonlinear damping mechanisms in a vibration isolator
(2013-02-04)
The vibration transmissibility characteristics of a single-degree-of- freedom (SDOF) passive vibration isolation system with different nonlinear dampers are investigated in this paper. In one configuration, the damper is ...

Acute effect of whole-Body vibration in a female dog with metritis
(2017-01-01)
Background: Whole-body vibration is a modality of exercise used in humans for therapeutic purposes or to increase physical performance. In veterinary medicine there are only a few reports on the use of this technology. The ...
Optimization of Axial Vibration Attenuation of Periodic Structure with Nonlinear Stiffness without Addition of Mass
(2020-12-01)
We explore the vibration attenuation of a periodic structure when one absorber with nonlinear cubic stiffness is included without increasing the total mass. Metastructures, and specifically periodic structures, present ...
Thoracic vibrations in stingless bees (Melipona seminigra): resonances of the thorax influence vibrations associated with flight but not those associated with sound production
(COMPANY OF BIOLOGISTS LTD, 2008)
Bees generate thoracic vibrations with their indirect flight muscles in various behavioural contexts. The main frequency component of non-flight vibrations, during which the wings are usually folded over the abdomen, is ...
