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, ...
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 ...

Harvesting Energy from Time-Limited Harmonic Vibrations: Mechanical Considerations
(2017-10-01)
Single-degree-of-freedom (SDOF) mechanical oscillators have been the most common type of generators used to harvest energy from mechanical vibrations. When the excitation is harmonic, optimal performance is achieved when ...
Freezing of gait in Parkinson's disease: Evidence of sensory rather than attentional mechanisms through muscle vibration
(2016-08-01)
Introduction The role of proprioceptive integration impairments as the potential mechanism underlying Freezing of gait (FOG) in Parkinson's disease (PD) is still an open debate. The effects of muscle vibration (a well-known ...
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 ...
Recent Advances in Shock Vibration Isolation: An Overview and Future Possibilities
(2019-01-01)
Mechanical shock is a common problem that is present in many situations, such as ground motion, blast, explosions, crash, and impact. The development of passive, active, or adaptive control and isolation strategies for ...
Diseño e implementación de un software para el análisis de vibraciones mecánicas mediante los métodos energéticos de RAYLEIGH-RITZ y MEF híbrido
(Juan Carlos Ramos Bermejo, 2017-05-24)
This Tesis deals with the implementation of the Rayleigh-Ritz method through a
code developed in Matlab, solving practical examples as the deflection of a beam,
and torsional vibration of bars and vibration of plates. ...
