Nonlinear Dynamic Behavior of a Flexible Structure to Combined External Acoustic and Parametric Excitation [PDF]
Shock and Vibration, 2006 Flexible structures are frequently subjected to multiple inputs when in the field environment. The accurate determination of the system dynamic response to multiple inputs depends on how much information is available from the excitation sources that act ...

The excitation of waves on a flexible panel in a uniform flow
The wave-bearing behaviour of a finite flexible plate in a uniform flow is studied when a source of continuous oscillatory excitation is present. The method of numerical simulation is employed so that any prescription of response is avoided. A series of numerical experiments is carried out and analysed using methods similar to those applicable to a ...

Using novel simplified models of excitation for analytic description of initiation propagation and blockage of excitation waves [PDF]
, 2006 We consider applications of a recently suggested new asymptotic approach to detailed ionic models of cardiac excitation. First, we describe a three-variable approximation for the excitation fronts in a detailed ionic model of human atrial kinetics.

Reciprocating excitation of a flexible beam: Benchmark study [PDF]
Mechanism and Machine Theory, 2006 Abstract A long and slender flexible beam is set in oscillatory motion to observe its deflection. A novel application of digital image processing is employed to obtain contactless discrete measurements of the beam tip deflection. We compare the measured data to those predicted by a flexible multibody dynamics simulation ( flxdyn ).

Quantification of dynamic excitation potential of pedestrian population crossing footbridges [PDF]
, 2011 Due to their slenderness, many modern footbridges may vibrate significantly under pedestrian traffic. Consequently, the vibration serviceability of these structures under human-induced dynamic loading is becoming their governing design criterion.

Bifurcation control of a flexible beam under principal parametric excitation [PDF]
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000 A new approach is proposed in this paper for the nonlinear control of a flexible cantilever beam which is excited under a principal parametric vibration. The approach is based on a bifurcation control principle that combines linear and nonlinear feedback control strategies. A simplified nonlinear vibration model that accounts for the beam's flexibility
