Recent work in rail vibration has investigated methods for estimating track support stiffness from trackside vibration. This vibration, induced by the passage of a train, is mainly due to the load applied by the wheels, ...

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 ...

Vibrational contributions to the 3JHH couplings of six mono- and five 1,1-di-substituted ethanes, three mono-substituted cyclohexanes, three norbornane-type molecules, and 11 three-membered rings have been calculated at ...

This paper presents the implementation of a Shape Memory Alloy (SMA) actuator in a so-called non-ideal system with the objective of reducing the mechanical vibrations and the Sommerfeld effect present in this kind of system. ...

Lyapunov-based control is an attractive strategy for semi-active vibration control as it has a mathematical basis ensuring stability in the sense of Lyapunov and great flexibility in the design. Unfortunately, that flexibility ...

The vibration on the solidification of aluminum alloys results in grain refining, more homogeneous microstructure and also contributes to degas. The objective of this paper is to evaluate the effects of mechanical vibration ...

High levels of vibration coming from agricultural machinery can be transmitted to the operator’s body, requiring the need to create or enhance devices that allow the measurement of vibration levels. Design cost-effective ...

The scientific career of Vicente Lopes Jr at UNESP—Ilha Solteira—spanned three decades in which he worked on new applications of smart structures in structural health monitoring and active vibration control. Prof. Lopes ...

Successful experiments in nonlinear vibrations have been carried out with cantilever beams under harmonic base excitation. A flexible slender cantilever has been chosen as a convenient structure to exhibit modal interactions, ...
